Brett Bloom, DPT, CSCS, FAFS, owns Longevity Physical Therapy in Grantville, San Diego, operating from 4635 Mission Gorge Pl, Suite B, 92120. Bloom earned his Doctor of Physical Therapy from the University of Southern California in 2001 and completed a year-long fellowship with the Gray Institute, earning the Fellow of Applied Functional Science designation. The San Diego location opened in 2012, and hospital discharge referrals from East Campus Medical Center at UC San Diego Health feed post-surgical patients into the Grantville clinic for hip, knee, and shoulder rehabilitation programs. Applied Functional Science drives the treatment model: therapists assess root-cause dysfunction through three-dimensional movement analysis rather than isolated joint testing, building individualized plans around each patient's activity goals. Equipment includes an AlterG anti-gravity treadmill for reduced-load gait retraining and TrueStretch multi-plane flexibility stations. Bloom previously served as a clinical instructor of physical therapy at USC and consulted for USC's athletic department, bringing collegiate sports medicine protocols to a civilian rehabilitation setting. His Certified Strength and Conditioning Specialist credential adds sports performance programming to a clinical practice now employing approximately 27 staff across four county locations. Climbing and bouldering athletes at Grotto Climbing & Yoga on the Mission Gorge corridor represent one segment of the active patient base that uses the Grantville clinic's vestibular therapy, pelvic floor rehabilitation, and post-operative recovery programs. The 92120 ZIP positions the facility just off the I-8 interchange on Mission Gorge Road, within the commercial stretch that connects Grantville to Mission Trails Regional Park and SDSU's eastern campus boundary. Longevity Edge, a concierge out-of-network tier, provides one-on-one sessions without insurance-driven visit constraints for patients prioritizing long-term performance outcomes.
