— Patient review of Dr. Andrew Knoernschild

"I do not recommend this doctor. I have seen her for a few years and every single visit I felt rushed. She would get up to leave and i still wasn't done talking about what i wanted to talk about."

— Patient review of Dr. Amy Miller

"Shady billing practices. I had my annual physical with my Dr. As part of that physical, they do an annual blood draw that normally is covered by insurance. I had some questions during my visit which prompted them to change my visit from an annual... to a diagnostic... and got billed for things I shouldn’t."
