Q & A

Q & A

Q: Why did you become a doctor/reproductive endocrinologist?

A:

I have always been interested in science and discovery and remain ever curious about how things work (whether considering the human ovary or the garbage disposal in our kitchen). Centuries of research and experimentation have shaped our current understanding of human physiology and have enabled us to develop improved treatments for many conditions. While advances in basic science can be thrilling, these are often incremental and riddled with false turns and roadblocks; in contrast, the practice of medicine often yields immediate and highly gratifying results for our patients. In my career I have been fortunate to experience both sides of this equation...the methodical slog of research and the immediate reward of, say, removing an ovarian cyst or helping a couple to become pregnant; which is to say that I find my job to be both a privilege and personally gratifying.

Q: Who inspires you?

A:

I'm inspired by people who succeed against great odds and especially by those who, given the choice to take the easy road, instead just "do the right thing." Think Raoul Wallenberg or Oskar Schindler; men who could have looked the other way but, instead, risked their lives to save innocents during the second World War. I value persistence and hard work...especially when it goes unrecognized or unrewarded. I think that this world could use a little more civility, compassion, patience, and empathy.

Q: What are your hobbies and why do you enjoy them?

A:

Woodworking, home repair, cooking, eating, spending time with my family, and Eagles football (in no particular order). Then eating, again.

Q: What is something about you that would surprise most people?

A:

I'm a Type-A personality with a Type-B sense of fashion. I love order. I check and double check. I clean. That said, I don't like to shave and I prefer to dress casually (for my patients, I suppose this comes as no surprise). I'll try any food...twice.

Q: What about SGF makes you the most proud?

A:

I am deeply impressed with the intelligence and commitment of my colleagues and staff at Shady Grove Fertility. Beyond this, I observe an insistence on evidence-based and state-of-the-art care. This is coupled with a focus on the patient and his/her experience from the time that care is initiated to the successful completion of his/her sometimes frightening journey. Our team approach to healthcare is personalized for each couple and benefits from our vast clinical experience, ongoing discovery, and our cadre of world-class providers who genuinely care.

Q: What's on your bucket list?

A:

I'd like to visit the Tsukiji market in Japan, the largest seafood market on earth. Then, I'd like to taste "one of everything" in the market...including Puffer Fish/Fugu.

REVIEWS

Reviews

"Dr. Kallen is extremely knowledgeable and keeps up-to-date on latest studies. While he has a very calm, serious demeanor, underneath it is a caring, compassionate human. He's very informative, lays out your options and lets you take it from there. His nurse and him work like a well-oiled machine - the care they provide is remarkable. Questions are always answered promptly. The entire team at Shady Grove Fertility-Chesterbrook is phenomenal. Thanks to Dr. Kallen, we are expecting this spring!"

"I could not have asked for a better experience with Dr. Kallen and the staff at Shady Grove Fertility, Chesterbrook. Dr. Kallen and his nurse Chrissy were more than happy to answer all of our questions and help with any concerns my husband and I had. They truly went above and beyond to keep us informed. The staff at Shady Grove allowed us to feel more than comfortable and supported in situations that aren't always so easy to go through. After our first IUI I am now pregnant!! A super huge Thank you goes out to everyone there!"

"I have been seeing Dr. Kallen for 6 months now. He has reassured me every step of the way and his optimism is precious to me. I never leave his office with questions. I would highly recommend Dr. Kallen as well as all of the amazing nurses at Shady Grove!"

"I came to Shady Grove after spending a year being seen by another clinic with no results. I saw Dr. Kallen at every single appointment. He told me exactly what he was doing and what the next steps were. I felt like he and the staff at Shady Grove took the time to get to know me and my husband. I'm now 12 weeks pregnant, and wouldn't be without Dr. Kallen and Shady Grove"

"Dr Kallen and his staff at Shady Grove were absolutely wonderful! I felt like they really took the time to get to know us and answer all of our questions and concerns They were right by our side every step of the way from office visits to emails to phone calls. I am extremely thankful for all of their individualized care and positivity. After only 1 IUI treatment we are expecting our first baby!! I couldn’t recommend anyone else."

"Dr. Kallen is very knowledgeable, and someone I would recommend to anyone struggling with infertility. I'm someone who likes to know "odds" (if we choose treatment A, what are our chances of success? and so on) and he was always willing to take the time to explain this. He never pressured us into a particular route, just provided the relevant information necessary for my husband and I to choose what treatment was right for us."

"My husband and I spent 9 months receiving treatment from another 'highly" recommended fertility provider in the area. After ZERO success we decided to leave and give one last chance for IUI with Shady Grove. What a world of difference, Dr. Kallen and the entire staff at SGF provided top level patient care with kindness and empathy that resulted in pregnancy after three short months! Don't waste precious time anywhere else!"

"I cannot recommend Dr. Kallen highly enough. He was always clear and informative yet compassionate and sensitive. He quickly put us at ease during a stressful time. Because of him we are now expecting our first! He performed a necessary surgery and all IVF procedures and always made me feel comfortable and confident in him. We are so thankful for Dr. Kallen and the entire Shady Grove team."

"I cannot recommend Dr. Kallen highly enough! He was always clear and informative yet compassionate and sensitive. He quickly put us at ease during a stressful time. Because of him we are now expecting our first! He performed my surgery and all procedures and always made me feel comfortable and confident in him. We are so thankful for Dr. Kallen and the entire Shady Grove team. After a long journey of trying to conceive at another facility we ended up at Shady Grove and are so thankful that we did! Our experience there was vastly different from anywhere else, in a wonderful way. And in a short period of time we got the wonderful news that I was pregnant. We were sad to "graduate" back to my regular OB after receiving such warm and kind treatment at SGF. There is no way to thank them enough!"

"Dr. Kallen eased our worries from day one. He gave us hope that we had lost after trying to conceive for 2 years. He was always attentive, informative, kind, thorough, and answered any and all questions we had. Thanks to Dr. Kallen and the whole Shady Grove team we are now expecting our first child. Words can not describe our gratitude to Dr. Kallen. Thank you for believing in us and helping us start a family."

"Dr. Kallen was very informative and focused on our physical and emotional well-being through the whole process. My thoughts and input were welcome throughout the treatment process. I have already recommended him to others."

"Dr. Kallen was thorough and informative. He took the time to listen to our story and let us ask any questions we had. He walked us through each step of the process as we narrowed down the possible causes of infertility. He was very straightforward and knowledgeable."

"Dr. Kallen was fantastic, helpful and kind. I really appreciate how much time he spent with us up front, explaining, in the detail we wanted, our options. He is definitely a cool, calm and collected presence, which is helpful in such uncertain and sometimes unconfident times. The entire Shady Grove team, though, were wonderful and made our experience. They were all wonderfully kind and generous with their time and made us feel like a family member, even though we, luckily were only there for a short time."

"He was so helpful, very informative and factual, very knowledgeable and his treatment strategy worked right away. He was very confident, despite my concerns! He took extra time with my first ultrasound and helped me feel comfortable when I was really nervous."

"Dr. Kallen was very helpful, knowledgeable, compassionate, and confident. He came up with a treatment plan and it worked right away, despite the odds. His staff is so nice and super responsive as well. I have recommended this practice to others already!"

"Had my new patient appointment with Dr. Kallen. Even though it was just my first appointment, I could tell that he is truly a great dr. He was patient, informative and very professional. I also cannot rave enough about the staff. Nina and Christine are absolutely incredible. So kind and compassionate. Highly recommend Shady Grove."

"Dr. Kallen took time to meet with my husband and I personally several times before helping us decide the best route for us to achieve our goal of pregnancy. He took time out of one of his weekends off to call me after a particularly difficult appointment to talk me through about important decision. When we had concerns he made sure to address them. When we finally got our positive result, he called me and shared in my joy! We highly recommend Dr. Kallen to any couple struggling to conceive!"

"I recently had a consult with Dr Kallen for ivf. Even though I was currently undergoing tx with another RE which I loved, they didn't offer a guarantee program which I needed for my own piece of mind. Dr Kallen spent approx. a full hour with me explaining all the ins and outs of tx. He was very patient and was very thorough with his information. I appreciated that he came out to the waiting room to greet me and take me back to his office and even though I was only there for a consult, due to where I was in my cycles he was able to do a scan and bloodwork that day. I also appreciated that he himself did my scan. I was then introduced to my own personal nurse Debbie who said she would be my nurse throughout the whole process and made me feel so comfortable and reassured me that i would be taken care of. Everyone was great there! I honestly didn't know what to expect and I really didn't want to leave my current RE but the experience I had with shady grove left me feeling confident that they would help my husband and I on this journey to conceive. I look forward to my future appointments with the staff at SGF!"
