Kevin Greer, DPT practices at Carlsbad's Bressi Ranch location on Loker Avenue West as part of the Longevity Physical Therapy clinical team, which has served North County since 2008 under the Applied Functional Science model. The Bressi Ranch clinic's evidence-based approach to functional biomechanics treats root-cause movement dysfunction rather than isolated symptoms, with practitioners holding Fellow of Applied Functional Science (FAFS) certification from the Gray Institute — a credential shared with musculoskeletal providers in the same corridor including NuSpine Chiropractic - Bressi Ranch. Greer's caseload encompasses post-surgical shoulder and knee rehabilitation, vestibular disorders, and fall-prevention programs for older adults near the Palomar Airport Road commercial district. Diagnostic imaging referrals for patients presenting with complex orthopedic pathology route through North County facilities such as SimonMed Imaging - Carlsbad before treatment planning begins. The vestibular rehabilitation program deploys computerized dynamic posturography and infrared videonystagmography to quantify balance deficits and track recovery across six-to-twelve-week intervention cycles.
