"Dr. Stein has always been very helpful, considerate, respectful and takes the time to explain everything in a way I can understand. I never feel rushed. He has been a great help to me and has done his best at all times."
— WebMD patient review for Dr. Adam Stein"She gave me a vague answer, with an attitude as if I was inconveniencing her... she proceeded to tell me that my blood work came back normal and my symptoms (Swelling, Hair falling out in large chunks, etc) were all in my head and I was faking it."
— Vitals patient review for Dr. Demetra Rupp"He treated my 11 y.o. daughter like she wasn’t in the room... didn’t listen to the whole picture. Completely ignored the many symptoms she has... He had no interest in finding out why her labs are abnormal."
