Dr. Agnes has a wonderful bedside manner. I have only seen him distracted 1 time in all the years I have been with him. I have referred many friends and family to him and they like him as well.

Dr. Agnew has a wonderful, calm manner, but did not see me as a person, only a bad knee. His only response to my concern about the progression of my osteoarthritis requiring two ankle braces & reverse shoulder replacement was he "could give me a referral to a rheumatologist, but it won't do any good."
