Meet our Expert Physical Therapists

We win Best PT Practice year after year! We know it's important to address your symptoms now - but more importantly - correct the source of pain. This makes you feel better now and prevents your problem from coming back. Wouldn't that be nice? Once we have determined the source, we develop a personalized plan. We understand the mechanics of your body. All of our therapists believe that making sure the physics of you are optimized. We get to the reason why you either developed a problem gradually or what might have been thrown off by injury or surgery.

  • You may also meet the therapist in a FREE 15 minute consultation where we listen to you and will tell you if we can help.
    Call 703-723-7726 to schedule your free screening.
  • We have worked hard to recruit ONLY the BEST! All of our therapists are highly trained and have many years of experience. We have therapists who specialize in different areas of the body as well as different sports, such as dancers, tri-athletes as well as young athletes. Please check out their brief resumes to see who would match the best with you. If you have any questions, please call, we can fill in the gaps!

The most important thing about our techniques is that we are founded in mechanics. Specifically your body's mechanics or biomechanics. All of our therapists believe that making sure the physics of you are optimized to get to reason of why you either developed a problem that came on slowly or what mechanics or physics might have been thrown off by your injury or surgery. We use our hands and mechanical tools to measure and evaluate, our analytical minds to solve the problem and our hands to restore you to perfect!
