Patient Reviews
Mar 22, 2019
I travel over an hour just to be seen here. I live 15 mins away from a large university medical hospital, but found them impersonal, and one hand not knowing what the other was doing. After much frustration, I found Dr.Kretschmars office and couldn't be more pleased. Everyone from the office staff is pleasant, most important even when the NP wanted to reassure me on a call for my lab work, she knew I was uncertain, so she went to Dr.Kretschmar to ask if it needed attention. They are professional
