Dr Bill has been taking care of me for 26 years. I came to him with a heart issue from the USAF and he was very proffessional, competent and caring. The entire group of Dr's are excellent. Hartrich is the best Dr imaginable, and I'm very lucky to have him. Thanks Bill!!

Best doctor ever, is ready to answer any question you have and put your concerns to rest. Has taken care of our family since he started and is fresh today as he was when he started practicing. We don't know what we are going to do when he retires.
