I have one relative who had a total knee replacement with Dr. Welch in the past. This surgery was a complete fail, the knee was still very stiff after several courses of physical therapy.
Also one of their front desk ladies that you will deal with to process your insurance is very rude and unwilling to help. She acted like she is the boss. I don't want to mention her name.
Plus the therapy place right next to their office is horrendous, the female therapist is not friendly at all, and has no heart. Very lazy!! You will end up with doing the same exercises over and over again without any supervision and direction.
I am just sharing a little story here, please do your research and find another Doctor to take care of your needs. Hope this is helpful!
