My first time going to a Gastroenterologist, and I was nervous regarding having to schedule my colonoscopy, but Dr. Sapienza walked me through the process and made me feel very comfortable. I was able to then schedule the procedure immediately after our meeting.

June 14, 2026Lilia B.Verified patient

He made me really comfortable. I didn’t have a good experience with previous doctors but I just wanted a doctor to be nice to me and do something different and that’s what he did. You can tell he’s really genuine

June 12, 2026Kayita R.Verified patient

I had a great experience.

May 13, 2026Anna L.Verified patient

This was my first appt with Dr Mahpour. While it was a brief appt and I need to escalate my level of care because of my condition, Dr M listened to me patiently, asked questions to understand the situation fully, and initiated communications with my referring doctor. He also offered to call over to the ER to inform them of me and his recommendations before my arrival. I will go to back to him in the future.
