I imagine that most recommendations for physical therapist comes from a Dr. I had an injury on my shoulder and he gave me a suggested PT to go to for help. That would be one place to go offline to see how you get to be a qualified supplier to an orthopedists. One creative approach to this might be to start a podcast where you interview orthopedists about the role of PT. That way, you get to meet them in person and build a connection with them. The podcast could build your personal brand nationally but the real objective is getting to meet orthopedists. It can be done by phone to make it easy for them but at least you get to connect with them directly.
For more ideas, give me a call through Clarity.
