Patient Testimonial
A huge thank you to Leslie and Dr. Kim and the amazing clinical coordinator Dori who have been fantastic the whole way. The kindness and compassion fills the room and the organization and professionalism creates an environment of peace, trust and comfort.

Dr. Robinson was great to work with, he took what could have been an incredibly scary surgery and made it approachable and eased all of my fears. He has a wonderful bedside manner, and I am so grateful that he was available to perform my procedure.

After our first appointment with Dr. Kallen we knew that he would be the right doctor for us based off of the knowledge, honesty and compassion he showed. We will be forever grateful to Dr. Kallen and his team!

I have been to 5 fertility clinics and seen 6 fertility doctors. Dr. Bressler and Shady Grove was hands down my best experience…by a landslide. Dr. B made me feel like an important individual. I can’t say enough good things about this practice and about Dr B.

At no point in time did I feel hopeless and was always comforted by next steps and kind words. But Dr. Mitchell truly is extra. I felt like her only patient. I can’t speak enough to her kindness. It is my firm belief that she 100000X capable of leading someone to pregnancy success.

I had a wonderful experience with IVF at Shady Grove. The staff were incredibly friendly and supportive throughout the entire process. I am especially grateful for Dr. Sally Vitez, whose positivity and expertise made a significant difference. I couldn’t be more thankful for her and the entire team!

Q&A

As a young girl I was taught many baseless things about contraception and reproduction, so to better educate myself, I pursued the study of developmental biology as an undergraduate where I was introduced to hormone function and embryonic development. During my medical training, reproductive endocrinology became a natural path to follow based on my interest in reproductive health. As I cared for more infertility patients, I became passionate about finding and researching solutions to help patients have a healthy baby. I am thankful my path led me to become a reproductive endocrinologist because I am not sure there is a more rewarding job than helping people build their families.

Listening to my patients and their experience is the single most important thing I can do to understand why someone is struggling. It is important to me that my patients feel heard. This provides a basis for trust, mutual respect, and shared decision making so, together, we can effectively help them achieve their reproductive goals.

I am always inspired by my patients. Their willingness to be emotionally vulnerable about their most personal experiences in my office is inspiring. I see strong people every day in my office who are walking a long, difficult path and display such tenacity and courage; I am inspired daily to go above and beyond to help my patients achieve their reproductive goals.

SGF is known as a pioneer in many ways, shown through their commitment to research, innovation, collaboration, and education. I’m proud to be a part of a practice of this caliber, home to award-winning physicians who continuously and safely push the envelope and offer the very finest in care.

My mom is my biggest inspiration. She immigrated to the U.S. from Guatemala after high school. Despite her interest in science, where she was raised prevented her from pursuing medicine as a female. My mom eventually became a nutritionist and dietician and raised me to understand that how we nourish our bodies is a form of medicine, too. She always fostered my love of science and has remained a constant inspiration to never take my opportunities for granted.

I love spending time with my husband and our three children. We are avid skiers and go to the mountains often. We enjoy seeing extended family whenever we can. I also enjoy being active outdoors, dinner parties with friends, and playing music.

I am charismatic, compassionate, and inquisitive. I tend to see the glass as “half full” but am also pragmatic.

I raced in triathlon collegiate national championships as an undergraduate.
