Very personable and a gifted surgeon
Dr. Desmarais was very professional and personable. He explained my situation clearly and answered all my questions. I need to make a decision for myself now. I felt no pressure from him.
Great bedside manner in the wall is willing to listen and help.
Dr Desmarais did a wonderful job on my hip replacement surgery and the rehabilitation and recovery process was amazingly smooth and easy! I was surprised at how quickly I was able to walk again without any props (walker or cane)…the daily routine of ice packs and mild exercises was just the right prescription for a speedy recovery and the whole experience was a breeze; I couldn’t be happier with the results and Dr Demaris deserves the excellent ratings 5 stars, thank you so very much for the great job you and your team did for me!
