I can’t say enough good things about my experience at Collab. Dr. Segal and the whole team are incredible! From our first meeting I really felt that Dr. Segal listened to my concerns and goals and took the time to get to know me as a person and a patient. Everyone on the team is so kind and compassionate. The level of communication is excellent and far exceeds what I’ve experienced at other fertility clinics in the past. The facility is beautiful and comfortable which is a really nice bonus too!

CASEY S.

My husband and I are absolutely blown away by Collab Fertility and Dr. Segal! From our first meeting, I was immediately struck by her compassion, clear expertise, kindness, and exceptional communication. Having been through the difficult process of IVF for over a year and using two other clinics, I speak from experience that there is NO ONE better than Dr. Segal and her clinic. We hope that through our own experience, others can benefit in their fertility journey like we finally now are.

Collab Fertility really took care of me from step one to the operating table! Dr. Segal and her staff are so caring and gentle. They really explain every single step so that there is no surprises. They were just so welcoming and kind!! I really can not sing high enough praises to them. I had a wonderful experience working with them and will def be doing so again in the future!
