Dr. Unison has been my doctor for over 15 years. He always listens and never tries to make you uncomfortable. He's very good at narrowing down the symptoms to get to the root of the problem. There's none better. He's awesome.

The Dr. used to send us a letter detailing our visit. That sure helped us old folks remember what he said. Now he doesn't do that and we sure miss it!
