He is the most compassionate doctor i have ever met. He listens without judgements and he is quick to come.to a solution. He doesn't waste your time with words you dont understand. He explains things smoothly and simply ro say the least. His compassion towards his patients goes beyond measure. All and all I wouldn't want any other doctor to do my surgery. He's awesome in every since of the word.

I am extremely happy with my knee replacement. Instructions after surgery were very clear, written plainly. He is personable and took time to answer all my questions. I had little to no pain. I had my 1st post op appointment at 19 days. My incision is incredible looking. I am using a walker part of the time and a cane most of the time. I did follow all directions and do all exercises assigned by my physical therapist. His clinic nurse Tiff returned my phone calls in a timely manner and is very knowledgeable.
