I cannot say enough good things about Dr Thambuswamy! His bedside manner is impeccable. He is empathetic, sympathetic and humble. Along with those qualities he is wise, precise, concise, professional, knowledgeable, skilled and expertly qualified. Do not hesitate to make your appointment with him. You will be a healthier, happier person for it.

Shows concern and is very up front regarding treatments that would or would not help you. Spends a lot of time with you and you do not have that rushed feeling.

I'm 73 with a pretty terrible back. This is the third surgery Dr. Harwell has performed on me, all at different levels. He corrected each symptom I had, all with no complications and minimum down time. I fully trust his expertise.
