What Are People Saying About Dr. Merrell?

Teddi Isherwood

Dr Merrill and staff are AMAZING! Due to a fracture in my femur, I had to have a complete revision a month after my first knee replacement. The fracture was due to undiagnosed Osteoporosis. I had no idea I had this. Dr Merrill and his nurses were so amazing. They went above and beyond for me, by calling and checking on me frequently, keeping me informed and helping me through the entire ordeal. My surgery was a complete success. The medical and emotional support, through this was incredible.

Jeff Grover

Dr Merrell replaced both of my knees simultaneously and I was golfing again within 7 weeks. Unfortunately, I fell into a sunken living room and totally tore the quadriceps off both knees. The muscles were severely damaged and Dr. Merrell also performed the repair surgery that same evening, Today, at age 71, I'm totally unaware of any sense of damage and can easily walk 18 holes of golf with no pain.
