Patient Reviews
Nov 06, 2025
I was a new patient with some not great previous experiences, and Dr. Ganz was caring and took his time! I was nervous to see a male OB but he was awesome. Took his time unlike many doctors and was considerate of my preferences! Didn’t suggest anything without asking what I thought. No judgement about birth control preference.
