About Bonnie L. Ashby, MD

It is important to me to listen to and try to understand the individual patient and the issues of health for that person and to be the advocate that not only cares about the person but also integrates their belief system and life style into the very regulated and controlled insurance run quality measures of “healthy.”

I want to trust my patients and I want them to trust me that I will care for them as best as I am able as a physician not a health care provider. I do not provide health care. I adjudicate it.
