Q & A

Q: Why did you become a doctor?


My father is a pediatrician and the practice of medicine was always in our home. He works very hard, and growing up I always heard him on the phone with patients. He served as a role model when becoming an adult. So my connection to medicine is very connected to my family life at home.

Q: Who inspires you?


I am inspired by my patients’ strength. I am inspired by my kids’ thirst for knowledge, love, and experience. I am inspired by my medical school classmates. I am regularly amazed at how diverse they are and how much they have accomplished. I am inspired by the nursing staff at Shady Grove Fertility who are on the front line of patient care and are always working for perfection. I am inspired by my best friend, a lawyer on Capitol Hill. He is full of energy and enthusiasm and always looking for the next meaningful life experience. I think he is acutely aware that we only live once and that we need to make the most of every single day.

Q: What’s on your bucket list?


I want to lie on a beach in Tahiti, dive on the Great Barrier Reef, and go on safari in Africa.

Q: What are your hobbies?


I enjoy woodworking, yoga, and spinning.

Q: What about you would most surprise people?


I come from a big family; I am the oldest of six. When my wife and I tried to expand our family we turned to treatment and we now have twins from an injectable cycle. At the time, no one told me there was a 20 percent risk of twins. It makes me acutely sensitive to patients that say “I’m okay with twins.”

Q: What about SGF makes you the most proud?


I think we do an amazing job at providing quality, evidence-based care, with attention to service and personalized to a patient’s needs.

I am inspired by the nursing staff at Shady Grove Fertility who are on the front line of patient care and are always working for perfection.


"Without hesitation, I would recommend Dr. Sasson to friends or family members in need of fertility treatment- in fact, I already have! He is very knowledgeable and through his guidance and treatment plan we are now expecting our first child in 2018. We could not be more pleased with the outcome of our treatment and will certainly be back to Dr. Sasson when we are ready to expand our family again."

"Dear Dr. Sasson,
Thank you so much for checking up on us in the OR on Friday. It meant the world to us as we were navigating this unexpected and difficult time. Our hopes were chewed up quite a bit and I was really emotional and a little irrational. Joe has been really supportive and I am feeling better about our hopes. I pray that God hasn’t forgotten us and your words gave us rays of hope on a very dark day. Thank you so much."

"Words cannot express the gratitude that we feel towards you for being the most supportive caring and compassionate doctor. Please know how much you have effected our lives and that we hold you in the highest regard and with all the love in our hearts."

"Dr. Sasson perfomed his duties with deep concern, professional knowledge, and exquisite sensitivity. Never have I know a doctor like Dr. Sasson."

"I just wanted to give our gratitude to you for the long talk last week when we came in to learn more about IVF and the donor egg process. We really felt comfortable and connected to you, personally. The thing that clicked for me was when you took the time, within our talk, to ask what our son's name was. It meant so much that you acknowledged him as a living and meaningful little soul rather than just an anonymous affected embryo. He is our world :-)"

"I wanted to thank you, Dr. Sasson, so much for meeting with us on Monday. I learned so much and was grateful to have met you. I am sad I did not find you earlier in our journey to have a baby. You are so kind and made us feel welcome in your office and not just another one of your patients. We cannot thank you enough."

"As I sit here with my 2 month old little boy sleeping on my lap, I can say that my experience with Dr. Sasson and Lisa Russell and the entire Shady Grove Fertility staff was exceptional. Having worked in the healthcare field as both a provder and administrator, I was continually impressed with the quality care I received from Dr. Sasson and everyone at the Chesterbrook and Bala Cynwyd offices. I went from being told I needed a hysterectomy from another physician in Reading, PA to holding my baby in my arms. I owe it all to Dr. Sasson. Can't say enough about him!!"

"Dr. Sasson and the entire staff at Shady Grove are exceptional. I could not ask for a more positive experience when dealing with infertility. My husband and I came to Shady Grove for unexplained recurrent pregnancy loss after another RE recommended that we simply keep trying. From our first meeting with Dr. Sasson he showed compassion for what we were going through, and he gave us honest advice as to what our best options were to achieve success. He is incredibly caring and always took the time to answer my questions and thoroughly explain things. His knowledge, his professionalism and his team made me feel at ease throughout our entire journey. Our wonderful nurse Lisa answered any questions we had and was always available by phone or email to guide us through the process. The entire Shady Grove team is very attentive. It was really comforting to be greeted by the same staff at each appointment. As happy as we are to have graduated to my Ob-gyn, it was very emotional to leave behind a group we have become so close to. Dr. Sasson and his staff are truly incredible and I would highly recommend them to anyone dealing with infertility. Thank You, Dr. Sasson, Lisa, Jami, Ted, Maria and Nina!!"

"We arrived in Dr. S's office after three years of trying to conceive and after being treated at two other clinics. Above all, he was an incredible listener and walked with us throughout our IVF cycles. We have a 2 year old whom Dr. S helped us achieve and we are now 14 weeks pregnant again with the help of SGF; I highly recommend Dr.S and Shady Grove Fertility."

"After 10 years of trying to conceive, many different Drs, many rounds of failed IVF and multiple miscarriages, I am now the Mom of a beautiful 5 week old baby girl thanks to Dr Sasson and his team. They are extremely skilled, competent, caring and compassionate. I never felt rushed when speaking with Dr. Sasson and I didn't feel like I was on a conveyer belt of patients which is how I felt at other practices. He took the time to consider all of my history and was always very encouraging while not giving false hope. I cannot recommend Dr. Sasson and Shady Grove Fertility enough."

"Dr. Sasson and his staff are simply the best. I felt a very personal connection with them, and when my procedure was successful, I knew they were as happy as I was. They are exceptional at what they do from a knowledge and capability standpoint AND the nicest, most caring people you're ever going to meet."

"He's the best. Dealing with infertility can be emotionally stressful, but he was very patient and answered all our questions and our concerns."

"Dr. Sasson and he staff are great!!! I came to him needing help. I have severe stage 4 endometriosis and only had 1 ovary left, and tubes were gone due to endometriosis. I went to Dr.sasson for help , and now I am blessed with 2 fraternal twin boys!!!! Thank you Dr.sasson and staff for all of your help!!! I now have the family I always wanted!!

"Dr Sasson is simply the best! He made us feel very comfortable from our first visit with him up until the day we were pregnant and being discharged. He is so gentle and has an amazing bedside manner. I would highly recommend him to anyone experiencing infertility. He was always very confident with his decisions and very knowledgable. The best of the best!!!"

"There are not enough good things I could say about Dr. Sasson. I have never in my life dealt with a doctor with such a wonderful bedside manner. He never let us give up hope and was our biggest cheerleader when we decided to move on to IVF. We got pregnant after one fresh transfer and I will be forever thankful to him for holding my hand through it all. Our little girl is due November 2016."

"I am a 2x gestational carrier. I have worked with 3 different reproductive endocrinologist, Dr. Sasson was by far the best! The staff and doctors at shady grove know their stuff. I would highly recommend this fertility practice to everyone, in fact I do! We transferred 2 healthy embryos and I got pregnant on the first transfer with boy/girl twins. The first ultrasound with Dr. Sasson was one I'll never forget. He's very kind and very real, two things that are important in the world of infertility. The twins are now 6mo, happy and healthy!"

"Dr. Sasson is one of the most kind and caring doctors I have ever met which means a lot coming from a nurse who has worked with a lot of doctors. His bedside manor is one of a kind and he truly has his patients best interest in mind. He made this scary process so much easier than it could have been. He is simply the best and I would highly recommend him to anyone!"

"I would definitely recommend the Shady Grove office at Chesterbrook. The whole experience was as positive as it could be given the situation. Nina in the front office, all of the nurses and Dr. Sasson were all made you feel as thought there was nothing to worry about."

"First off anything about fertility is very sensitive and the human body works differently for everyone, there is no one procedure that is sure to work for everyone. Yes, some of the reviews are right sometimes you do feel like no one is paying attention to you. It's a big practice you have to speak up to be heard. We all wish it wasn't so but that is the reality of it. I worked with Doctor Levy, I started in 2007. I suggested IVF and he refused saying he could not not do that based on the fact that there was nothing medically wrong with me (unexplained infertility). I have 2 kids from SGF the first kid I did 5 IUI's medicated and the 6th was a natural cycle and I had my son. For my daughter it was just once natural cycle. It was a long journey, I quit here and went somewhere else but came back again. All I can say is I love shady grove because they gave me what I wanted. I wish all of you peace that come here looking for where to go or write reviews on your experiences may your fertility journey be short and may you all carry you bundle of joys in the near future."

"After 3 years and three different fertility clinics, Dr. Sasson was the only Doctor to help my husband and I finally get pregnant. He is smart, compassionate, and skilled. He treated me as an individual. He gets results, and because of him, my two week old son is napping next to me."

"Before I saw Dr. Sasson, I went to three other fertility clinics and not one positive pregnancy test. I met Dr. Sasson at the Bala Cynwd office and he reviewed my medical records with me and also what my options were, he told me what my chances were getting pregnant using each option. He listened to my concerns and answered questions that my husband and I had. For the first time ever, I felt confident that I finally found a clinic that could get me pregnant. Four months later, I got my first ever positive pregnancy test, and my 2 week old son is currently laying next to me asleep. I am so thankful for Dr. Sasson and my nurse Abbie. Both of them were professional, and went above and beyond to calm my fears. I even had an ultrasound on Christmas Eve that Dr. Sasson performed."

"Dr. Sasson is awesome. Before I went to Shady Grove, I went to three other fertility clinics that treated me the same way they did everyone else. Needless to say, I never got pregnant at any of those places. Dr. Sasson reviewed my medical records with me and told me what my options are and the chances of me getting pregnant with each option. Under Dr. Sasson's care, I was pregnant within four months. My son was born two weeks ago, and I can not thank Dr. Sasson enough for his help."

"I would absolutely recommend Dr. Sasson and the Chesterbrook office. I really felt cared for in such a difficult time for me. Dr. Sasson really prioritized educating me so I felt like I was making the best decisions with all the facts and understanding possible. Of course, I also got pregnant successfully on my first embryo transfer, which helped with my overall positive experience!"

"Since my first appointment at Shady Grove I felt that I could trust on Dr. Sasson and the staff. Everyone was always very nice and helpful. Dr. Sasson always take his time to explain everything and answer all our questions. I really felt that we were in very good hands. It took only one cycle of IUI and we are pregnant with our baby girl."

"I went to Shady Grove because I was having no luck with my current fertility doctor. He did not go over alternative treatment and was not vested in my success. Unfortunately, my insurance would not accept Shady Grove and I was forced to go to another fertility clinic - one of the most prestigious and well known in the area. That clinic was not successful either, and when my insurance coverage was exhausted (5 IUIs and 2 IVFs later) I decided I needed to fund my success on my own and without insurance coverage, went back to Shady Grove. I went back 2 years later after my first visit and Dr. Sasson remembered me. He is very warm, friendly, kind and VERY helpful. He explains everything in great detail, goes over every treatment option, the success rate, and the costs. When I was at Shady Grove I felt like I was part of a family. They are very encouraging, helpful and enthusiastic and were excited for MY personal journey and outcome. Dr. Sasson was able to achieve what 4 years and 2 fertility doctors were not. My Twins Caitlyn and Chiara were born in December and are the most perfect babies. The only thing I have to complain about is that they don't have an OB practice. :-) When I left the office to now be under the care of my OB I felt like I was leaving my family. I miss them!"

"Dr. Sasson's bedside manner is wonderful. He helped us through several painful losses with compassion and consideration. He managed to give us hope while navigating options and next steps as we worked to build our family. The staff at the Chesterbrook, Reading and Harrisburg offices were always prompt and courteous. But more importantly, they generous with their support on difficult days. Happily, we delivered a healthy son and are very grateful to Dr. Sasson and Shady Grove's incredible staff."

"Dr. Sasson gave us peace of mind when we were in desperate need of it. He managed to give us hope while navigating options and next steps as we worked to build our family. He helped us through several painful losses with compassion and consideration. The staff at the Chesterbrook, Reading and Harrisburg offices were always prompt and courteous. But more importantly, they were generous with their support on difficult days. We delivered healthy child with Dr. Sasson's (and staff's) help."

"It is hard to believe that, last year at this time, we began working with Dr. Sasson and his exceptional team on the possibility of adding a child to our family. Because my husband and I are carriers of a fatal genetic disorder, and because I am over 40 with diminished egg quality and quantity, my husband and I opted to proceed with an Egg Donor IVF procedure to add a child to the family we began years ago. We are now grateful parents of a new baby boy, born just few weeks ago, who is an absolute blessing to us and his siblings. Thank you to Dr. Sasson and Shady Grove Fertility Center for making the improbable possible!"

"Dr Sasson is excellent at what he does. He cares and puts 100% into everything he does. I shared 1.5 years with him. He never gave up and always had hope for us. I would recommend him 1000 times again to anyone."

"Dr. Sasson and his staff are amazing. I am currently pregnant with my 3rd child. I cannot thank him enough for everything he has done for us over the years. I highly recommend him."

"I have nothing but outstanding things to say about Dr. Sasson. He is honest, sincere and passionate about his patients and their journey."

"Outstanding doctor! Dr. Sasson is honest, sincere and passionate about his patients and their journeys. We are so thankful to have found him and the Shady Grove team!"

"Dr. Sasson helped us make our dreams come true! He and the staff are so supportive, caring and understanding."

"Dr. Sasson was amazing throughout our time at Shady Grove. He was confident, positive, and friendly at every visit!"

"Patience and Persistent', were the words we took home after our first consult meeting with Dr. Sasson and his team who were absolutely amazing! They were all very passionate about helping us achieve our goal."

"Dr. Sasson is nothing short of amazing. His confidence and positive attitude was contagious, which was exactly what I needed. His knowledge is endless and he does an amazing job of making you, the patient, feel important."

"Dr. Sasson was the most amazing doctor. He obviously knew what he was talking about and was very knowledgeable, but even more important than that was how incredibly compassionate and kind he was to me during a very difficult time. All the staff at Shady Grove are excellent, and they keep a good schedule running smoothly. Every nurse and technician there was kind and professional, and the receptionist Nina was amazing too. I had a really good experience at Shady Grove and would absolutely recommend it to everyone."

"Dr. Sasson is an amazing doctor who I would recommend to anyone needing an RE. He was incredibly knowledgeable and really took the time to talk through options, success odds, and pros and cons with us. However, the thing that stood out to me the most was his amazing compassion and kindness with me during a really difficult time. He was invested not just in a successful pregnancy as an outcome, but with my overall well-being."

"The entire staff at Shady Grove from the front desk to the nurses, lab specialists and all of the Doctors including Dr. Sasson are amazing. They do not treat you as if you were a number like other clinics I've been to do. Dr. Sasson and his team genuinely care about the patients at Shady Grove. I highly recommend setting up time to meet with him if you are considering fertility treatments. When I had lost all hope of ever conceiving (after 3 failed iui's and 2 failed ivf's at another fertility clinic to remain nameless) Dr. Sasson helped me see the light at the end of a very long tunnel and I now have a healthy 16 month old. We are currently in the process of trying for #2 and I am very confident that Dr. Sasson and his team will do all they can to help make that happen."

"If you are looking for a Fertility Specialist who will be honest and patient with you, explain all of your options, and most importantly believe in you and help you believe in yourself then do yourself a favor a set up a time to meet with Dr. Sasson. His team at Shady Grove is amazing. You will feel like a patient who matters to them and not just a #. He helped us with baby #1 and we are currently working together for baby #2."

"We went to Dr. Sasson for diagnostic testing after a really poor visit with another physician. I am so glad my friend recommended Dr. Sasson. Dr. Sasson and his staff genuinely care about their patients. We recently got pregnant naturally, but had a miscarriage, and I went to the office for a D&C. While the circumstances were heart-breaking, it made all the difference to have such caring staff going through that. They are already great on a good day, so being taken care of and supported by them so well during this experience further solidified my high opinion of the people who work here. We recommend him to everyone we know."

"Dr. Sasson is very kind and understanding. He always took the time to answer any questions that we had. I couldn't have asked for a better doctor in this difficult time in our life. We can't thank him and everyone else enough for all of the help and compassion they showed us."

"Dr. Sasson and the entire staff at SGF helped through my fertility journey and delivered a miracle. They were there for me and my husband every step of the way. I never felt as if I was just a number and more so they provided quality care. From the initial consultation to the joyous news of pregnancy, I couldn't have had a better experience through such a difficult time. I would highly recommend Dr. Sasson and his staff for anyone seeking fertility treatment."

"Dr. Sasson was very knowledgeable about the infertility treatment process. His explanations were thorough and he made sure to take time for both myself and my husband."

"Dr. Sasson and the entire staff at Shady Grove feel like family. They are some of the best people I've ever met - they are genuinely good human beings who are brilliant, passionate, and they care deeply for their patients. I couldn't imagine going through infertility with any other Doctor or team. We were blessed with a little girl in 2014 and are now expecting our second (a little boy) in August. They have been there for us every step of the way. I was diagnosed with DCIS (early stage breast cancer) in between the two pregnancies and they were so kind and followed up with me to make sure that I was ok. They celebrate your successes with you and grieve for your loses and setbacks. And aside from being such amazing people, they are BRILLIANT Doctors. I always knew I was getting treated by the best in the field, which, at the end of the day was our main priority. I whole-heartedly recommend Dr. Sasson and team and wish the best for all families during the journy to start and expand their families!!!"

"I had the most fabulous experience! Dr. Sasson treated me like family, and I felt so comfortable with his expertise. He helped start my family and I couldn't be more grateful!"

"I cant write enough kind words about Dr. Sasson and his team! He provided safety, comfort, and ease in a not so typical situation. He made me feel hopeful from the minute we met. He treated my husband and I with the utmost respect and care, and I would recommend this practice to any person struggling with fertility. This is the only place in my mind in the world to go for help in starting your family. I loved every minute of working with him!"

"Dr. Sasson and the rest of the Shady Grove team were wonderful to work with through what can be a very stressful time. They offered personalized care and were easy to get in touch with between appointments. I would highly recommend Dr. Sasson for anyone struggling wth fertility issues!"

"Dr. Sasson and the whole team at SGF was a dream! You are not simply a number here. Everyone is rooting for you and has vested interest in your success!!!"

"Dr. Sasson and his staff truly showed me care and compassion from day one. I always felt like I was a priority to them and they were so prompt in responding to phone calls and emails. I truly felt like we were "in it together," as my successes were their successes and my tough times were tough for them as well. There was never a question too small to ask. At a time that is already stressful and emotional, they were exactly what I needed. I am so thankful for Dr. Sasson and his staff."

"The best decision my husband and I ever made was making that first appointment at Shady Grove with Dr. Sasson. He was the only doctor who treated us like real people, not a dollar sign. He took the time to explain our treatment plan and actually made us believe we would become parents. He made our dream come true! I can't recommend Dr. Sasson and the staff at Shady Grove enough."

"My husband and I couldn't have been any happier with our results. We just finished our 2nd IVF cycle and are 10 weeks pregnant with our 2nd child. Dr. Sasson and his staff are great and are there for you every step of the way. I never thought it would be possible to make a process like this "easy" but they really did that for us!!"

"Dr. Sasson and the SGF team were endlessly supportive during a very difficult time in my life. I felt like family here - so much so that once I got pregnant and "graduated," it was very bittersweet to leave the office for the last time! Thank you SGF for your compassion and dedication to your patients. I'll always remember the pain in my nurse's voice when she had bad news to share with me, and the joy in her voice when she finally was able to tell me I was pregnant. Isaac and Erica were right there with me, always by my side, through the entire process and I could not be more grateful for everything they have done for me. I'll be back when I'm ready for baby #2!"

"I’m not sure what I love most about Dr. Sasson, his compassion or his teaching skills. I loved his drawings and the way he explained everything. He wants his patients to ask questions and share their feelings. It is rare to find a doctor who cares so much for your feelings. Dr. Sasson also has a unique team approach that makes his patients feel like they matter. If anyone I know/care about ever needs an reproductive endocrinologist, I ALWAYS ALWAYS ALWAYS recommend Dr. Sasson!"

"I am pregnant with my second child as a result of IVF through Shady Grove with Dr. Sasson. He and his staff have always been so warm and welcoming, as well as supportive during what can be such a difficult time. I had such a positive experience the first time, I was actually excited to go back for my recent consultation - I wanted to see the people who helped me so much the first time."
