I feel like I received a thorough exam, and I understand the findings.

Dr Cowen is friendly, answers my questions, and explains things in an easy to understand manner.

I had a good visit with Dr Cowan

It a fan of your app, wait time in the lobby went beyond appointment time. The testing process went well, and time with the doctor was good.
