Excellent Doctor. We have had multiple surgeries through him, always with excellent results. My husband had knee surgery and I had shoulder surgery. Dr. Karzel is VERY personable and an amazing doctor. My husband had had 2 previous knee surgeries before going to Dr. Karzel and this was the first surgery that truely alleviated his pain. Great staff too!!

Dr.karzel seemed knowledgeable and professional. I waited far too long and was dissappointed with the wait time. This is less to do with the Dr. And more with the entire practice and lack of communication therein.

Dr. K was excellent. Professional and took the time to go over my xrays and offered/prescribed excersizes, medication and short term treatments that would help my knee recover. He was recomended to me by my Chiro Dr, Dan Massari. I am glad to know that there is no long term damage or injury affecting my knee and will do as Dr. K prescribed. Thanks and really liked using the ZOCDOC app to get my appt set up. Perfect tool for the patient.

Dr Karzel operated on my left shoulder, and both of my sons knees. My son is a successful Karate instructor and has had no problems with his knees since Dr Karzel operated on them 9 years ago. I HIGHLY recommend Dr Karzel
