— Patient review of Dr. Gary Knudson

"Dr. Naylor has provided treatment to avoid surgery for a few years and that has made me extremely happy. Now it has come to a point that knee replacement surgery is necessary and I have complete confidence in Dr. Naylor as my surgeon."

— Patient review of Dr. Richard Naylor

"He did surgery on my broken wrist. I only have about 40% usage after almost a year. The incision was the worst sewing up job I've ever seen... Not much of a caring personality either."
