Patient Testimonial
Dr. Gannon made me feel truly cared for—she was very thorough, kind, and knowledgeable, which really put me at ease. I went in feeling nervous, but left feeling completely comfortable and confident in her care. The entire team, including the staff, made me feel like a priority.

Shady Grove Fertility provides exceptional care and support under the expertise, knowledge and professionalism of Dr. Patounakis. He is incredibly successful at his work as well as thorough, compassionate and patient. I highly recommend Dr. Patounakis and the entire team at Shady Grove Fertility.

Dr. Kim and team are the best of the best. We switched clinics and have had a great experince. He truly listens to your concerns, never does the same thing twice, and is very involved in your journey. I would refer anyone to go to there in a heartbeat!

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. Kim is an amazing doctor and person. Since our first encounter with him, we just knew we were in the right hands. He is so very detailed, thorough, and kind hearted. He makes you feel comfortable from the moment you meet him.

Dr. Barnard is absolutely lovely and answered all my questions. She is very personable and kept us updated throughout the whole fertility process.

Q&A

As a resident, I met several role models who helped further spark my interest in the field of reproductive endocrinology. It became clear to me that helping people create or expand their families was one of the most rewarding things I could possibly do with my life.

Reproduction is the most significant process that we do as humans. If reproduction does not work, that is the end of our species!

I feel that it’s most important to cultivate and maintain the understanding that I am a member of my patients’ team. I am on their side. There can be so much unbearable frustration involved in prolonged fertility treatment, and I feel it is important for me not to look away and to make sure my patients know I am with them for the duration of the journey, no matter the outcome.

As a child, I was obsessed with Marie Curie and read her biography over and over. I usually never read a book twice!

Scuba diving, hiking, and cooking.

I love nature and hiking in Colorado is one of the best ways to enjoy it. Scuba diving is like hiking but underwater – it offers same feeling but with more equipment! Also, who doesn’t love eating a delicious and beautifully presented meal with friends and family?

I’m a sunny optimist for sure.
