Meet our Expert Physical Therapists
We win Best Physical Therapy Practice in Loudoun County year after year because at BioMechanic Physical Therapy, we know it's important to both address your symptoms now - but more importantly - we correct the source of your pain. This makes you feel better now but it also prevents your problem from coming back. Wouldn't that be nice?
Pain can come from different sources; injury, surgery, or something that came on gradually. We work to understand the problem or dysfunction within your body that is causing pain. It may be muscular, skeletal, or a combination of both. Once we have determined the source, we develop a personalized plan that will correct it. We understand the mechanics of your body and what is not working the way it should so we can help make you better.
This is how Dr. Lisa Allen, PT, came up with the name "BioMechanic Physical Therapy". When the body's mechanics aren't working properly it can cause pain. To compensate, you may begin to move differently, which causes secondary pain and problems. To stop the cycle, your body's mechanics may need to be restored or corrected.
- 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!
