Longevity Physical Therapy in Grantville operates a 5,500-square-foot rehabilitation facility at 4635 Mission Gorge Place, Suite B, in San Diego's 92120 ZIP. Founded in 2012 by Brett Bloom, the practice built its clinical model around Applied Functional Science — a framework from the Gray Institute that assesses movement across sagittal, frontal, and transverse planes rather than isolating single joints. Multiple therapists on staff hold the Fellow of Applied Functional Science certification, and climbing athletes rehabbing finger-pulley injuries and shoulder impingement cycle between PT sessions here and training at Grotto Climbing & Yoga in the same Grantville commercial zone. The San Diego location equips patients with an AlterG anti-gravity treadmill for reduced-load gait retraining after lower-extremity surgery, Normatec compression boots for lymphatic-drainage recovery, and a full strength-training floor for progressive loading. Specialty tracks include orthopedic rehabilitation, vestibular therapy for vertigo and post-concussion balance deficits, women's health pelvic-floor treatment, golf-swing evaluation, baseball-performance programming, and running-gait assessment. Mission Gorge Place sits one block east of Mission Gorge Road, the commercial corridor that funnels traffic between the 8 freeway and Mission Trails Regional Park. Patients combining PT with acupuncture for chronic-pain management coordinate visits with Mission Gorge Acupuncture in Grantville. Bloom has lectured nationally and internationally on Applied Functional Science methodology, and every treatment session at Longevity runs one-on-one with a Doctor of Physical Therapy to preserve direct-contact time per patient.
