Gregg-Ryan Chiropractic in College Area is the practice of Kevin Ryan, DC, CCSP at 7151 El Cajon Blvd, Suite J, San Diego, CA 92115, roughly a half-mile west of SDSU. The CCSP credential — Certified Chiropractic Sports Physician — designates advanced post-doctoral training in sports-injury diagnosis, on-field assessment, and rehabilitation protocols that distinguish Ryan from general-practice chiropractors along El Cajon Boulevard. Ryan holds NPI #1184796062 and treats back strain, lumbar disc herniation, sciatica, and sports-related soft-tissue injuries, drawing athletes from SDSU and high-intensity programs at Power Boxing Fitness & Sports Training in College Area where impact-related spinal compression cases originate. The 92115 ZIP address on El Cajon Boulevard positions the office on the primary east-west commercial artery through College Area, accessible from campus via College Avenue and from City Heights via Fairmount Avenue. Appointments are recommended, and the office accepts credit and debit cards. Patients recovering from acute sports injuries follow chiropractic adjustment with structured physical-therapy protocols, and Spine & Sport Physical Therapy in College Area runs the functional-rehabilitation phase for cases requiring progressive loading beyond what manual adjustment alone addresses. Ryan's pre-and post-adjustment treatment sequence includes soft-tissue mobilization and targeted stretching, a protocol designed to extend the hold time of each spinal correction between visits.
