Get Treated By An Expert

Southeast Physical Therapy was founded on the ideas of valuing the time of the client again and returning the healthcare decision making process​ back to the client and provider.  

Whether training for a 100 mile race, preparing for a weight lifting competition, professionally gaming or simply trying to move better; our goal is to be a resource for the community, athletes and active population.
