Dr. Mark Gardner is very knowledgeable, compassionate and an excellent surgeon. He has operated on me 3 times; two knees and a hip. I have had no problems afterwards. He is "number one" as far as I am concerned. I highly recommend him to all my friends and family.

Dr. Gardner is an excellent doctor. He was extremely friendly and caring about my issue. He was also very patient with me. I feel that he did not rush taking care of me. He gave me the time that I needed. I really appreciate his honesty and the way he/they took care of me.
