What real patients say about our expert physicians

“Dr. Alvarez is very kind and compassionate, while being professional, frank, and clear in describing everything you need to know to make an informed decision about your fertility journey.”

“Dr. Balmir is intelligent, kind, compassionate, supportive… I always felt like she was 1,000% in my corner, wanting this for me as much as I did.”

“Dr. Cooper has a way of making you feel like you are her one and only patient. She truly wants the best for her patients. She is a great listener and takes into consideration my thoughts and feelings before moving forward with any treatments.”

“Dr. Hayes is personable, warm and easy to talk to. She was able to give me a clear diagnosis, which I was unable to get from the two previous fertility providers that I had seen, and had a bedside manner that was clear and no-nonsense, which is a great combination in a provider.”
