We are a local, privately-owned PT clinic started by Sean & Diane Freeman. We’ve been in this clinic for over 15 years and pride ourselves on treating our patients like family.

We spend one- on -one time with each patient and use a team, whole-body approach to getting patients back to a healthy, functional pain-free lifestyle. We treat you like family– and we see repeat returns over the years. Friends and family referrals are what keeps us growing!

We treat everything from acute and chronic orthopedic and sports related injuries to neurological conditions and more.
