A great OB! Answers all my questions, and trust me I always have a million lol! Did an amazing job with me during my pregnancy and delivery. His nurses are the sweetest angels I have ever met! I love that he will listen to my concerns and take the time to chat with me about my options, he has never pushed anything on me, always gives me my options and helps me successfully follow the care plan that’s feels best for me! He really is an amazing guy!

The last time I saw Ganz he made me feel like a complete idiot for coming in and having questions about my fertility and wanting to find out what’s wrong with my body so I could plan on having kids.

I got blood work done and saw on my chart that my testosterone was one po... read more

I absolutely love Dr. Ganz and his nurses. He's been my OB through both my pregnancies with my girls. They have always listened to me and never made me feel uncomfortable or unheard as a women and in todays world that doesn't happen much.

If you’re looking for a OBGYN that just doesn’t deliver babies he is not the one you want to see. I originally went to Dr. Ganz hopeful that he would be able to assist me with issues I have been experiencing and he had no desire or to assist and just kept blaming it on the other MD’s I was seeing. Basically saying if they sent you to me then they basically are telling you they don’t have a clue what’s wrong with you so neither do I. In my office visit with him, he didn’t bother to even examine me. I’m honestly disgusted with... read more
