Dr Mercer has been our doctor for our whole entire family (9 people) for over twenty years.  He is very thorough and has built a rapport withall of us.  He knows our family's medical history and genetically speaking, that is a plus.  He is always on top of a sickness and makes sure we get to required testing when due.  I would highly recommend Dr Mercer as his skills, including bed side manner are top notch.

He was curious how I was doing and how he could help me on my visit . He came in the room shakes my hand, listened to my breathing and took my pulse ox and blood pressure . After he was done he asked me some questions and wanted to know how I was feeling. After the exam he wanted to know if I needed and prescription refilled and took care of that. Then we said our goodbyes and have a nice day and he went to see his next Pt .
