Dr. John Herath is a very personable doctor. Enjoy every visit with him and he hears me out and tries to work with me to address any health concerns I have. Appreciate that a lot. I have went through a lot of great doctors that retired on me. Very difficult to find ones that you like and are on the same page with. I am very happy with my level of service with him.

After 25 years with Dr Herath the registration desk is telling me that Gundersen is no longer working with Humana and the business desk says I either need new insurance or I need to find new providers for medical services. A "we'd late to lose you" would have been nice. I don't want to lose Dr Herath or the teams involved in my cochlear implant and my knee replacement and my wife's post cancer follow through. Some help would be nice.

I was randomly assigned Dr Herath as my primary doctor years ago. It was one of the luckiest things that ever happened to me. He turned out to be a fantastic guide in health matters, and has always been open and honest with any healthcare subject I have asked about. Well done Dr Herath, and thank you.

It was great to see more male drs. and nurses. They were both very comforting and professional. (fatherly demeanor), LISTENED WELL, gave common sense suggstions, not immediately expecting major health problems or rushing to do expensive testing. Came away comforted and with good advice.
