Patient Testimonial
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!

Dr. Davis is the sweetest doctor and Dee is so wonderful I couldn’t imagine going through this journey with any other clinic. Thank you guys so much for everything. If you thinking about doing IVF this clinic is beyond everything you need for your fertility journey.

Dr. Lersten is so kind and explains procedures calmly, which helps relieve anxiety while going through the difficult process of fertility treatments. I am thankful to SGF for helping me build the family I’ve always wanted. I highly recommend SGF to anyone going through infertility.

Q&A

I saw becoming a doctor as the perfect opportunity to merge my academic curiosity with my passion for learning people’s stories and making a positive impact on their lives. I am also the first doctor in my family and am committed to mentoring students with similar interests, as I was very fortunate to benefit from multiple giving mentors.

Towards the end of my medical school training, I spent two weeks in a Reproductive Endocrinology office. I witnessed firsthand how closely REI physicians work with their patients as a team, and how gratifying it is to help achieve the ultimate goal of building a family. After completing a fellowship in medical genetics, I appreciated how reproductive endocrinology intertwines with genetics by incorporating scientific advancements, while also promoting patient advocacy in day-to-day practice. 

I am very fortunate to be joining a team that makes a conscious effort to prioritize each patient and their individual journey. Every member of our team plays a significant role that is centered around providing the patient with the best possible experience. With this core value in mind, SGF also applies evidence based practices and contributes to growing medical knowledge to continue advancing the field.

I believe that to help a patient who is struggling, I first must stop and truly listen. I also feel that it is important to educate patients so that they feel empowered to ask questions and advocate for themselves. In doing so, we can formulate a plan as a team.

My parents left everyone and everything they knew in South America as young adults in the hope of providing more opportunities for their future children. They worked day and night to provide for me and my siblings. Parental love is selfless, limitless, and completely inspiring to me. 

I have been cliff diving in Greece and bungee jumping in Canada. I would love to go skydiving one day! 

While I won’t claim to be very good, I enjoy the feeling of accomplishment after a run or workout session. I was previously on a competitive Latin dance team and still enjoy dancing socially. As much as I love to explore new countries and hiking trails, I also appreciate a night in with my family, including our French Bulldog.
