Anonymous (RateMDs) Dr. Allan is an incredible orthopedic doctor. He has operated on most of my family and we refer to him as our "Orthopedic God". I would feel safe as long as I was in his hands. They don't come with any more expertise than him. God bless him!
Shirlene Wilken (Google) Dr. Allan is not the most outgoing doctor I've ever had, but quite nearly the best. I've had countless knee surgeries with other doctors, but Dr. Allan was the only one who was able to fix my problem and get me walking again.
Gil Belles (healthgrades) Fantastic surgeon. I've sent about 12 people to him for hip replacements and they have all thanked me.
