I had no time to ask questions, he talked over me, he shoved me around to do the examine as fast as possible, he prescribed me things with no explanation or direction, I ended up with products I didn't understand or know how to use. I had no time to explain the situation. I never want this provider again

Dr. Knopf, as always, listened carefully to me as I explained how my bladder infection was behaving. He has been our family physician for years and had never not been brilliant in diagnosing the problem, ordering the best medications, and sending me to the perfect care for my specific needs.

Dr Knopf has been my Dr since he came to the clinic. Probaby 30 - 40 years. Just the other night he spent a couple of hours on the phone getting me medicine and spent 36 minutes on hold at Walgreen. He is an excellent doctor and I am lucky to have him.
