Optimum PT and Sports Medicine (OPT) has been serving Loudoun County since 2008. What began as a solo practice has grown to include a dedicated team of physical therapists and physical therapy assistants. We are committed to continued education and applying the latest knowledge, techniques and technology to our patient care.

Each therapist has their own style and techniques that they bring to patient treatments. We encourage you to schedule and work with whomever you feel most comfortable.
