Dr Cooper was very thorough with my wellness visit. It was nice that he recognized that I maintain a heathy exercise regimen.

Dr. Cooper is a positive, thorough, attentive physician, an asset to the Oconomowoc Community and irreplaceable. His nurse was excellent as well. Thank you Dr. Cooper.

Unfortunately this appointment was a waste of time and money! Next time I feel ill, I will definitely think twice before going to your office.

Every interaction with personnel was great. Pleasant, helpful, courteous.Dr. Cooper always listens and answers questions using easy to understand language. He reviews my medical history and medications and gives me suggestions for things like vaccines, lifestyle changes, etc., and points out things to watch in the future. I leave my appointments, feeling "well cared for."
