Concussion Specialty Program

We provide comprehensive post-concussion care to patients experiencing symptoms such as headaches, dizziness, and balance issues, with a focus on returning them to work, school, sports, and other normal activities. 

In order to qualify for our in-house Concussion Specialty Program, our distinguished physical therapists must have demonstrated a passion for achieving superior patient outcomes in patients who have suffered a concussion, aiding them through an effective recovery plan that is both individualized and patient-centered.

In addition to pursuing a rigorous course of continuing education, EXCEL’s concussion specialists actively promote community awareness about concussion prevention and symptoms. We work with premier local physicians, surgeons, and rehabilitation experts to set up in-services (in-house seminars) where our therapists can learn about new procedures, cutting edge techniques, and emerging rehab protocols and best practices.

Our Concussion Specialty Program also provides a venue for our clinicians to collaborate on particularly difficult or complex cases, which ensures that every patient receives the benefit of the best, most advanced knowledge that EXCEL has to offer.
