Spine Research Institute of San Diego in Coronado, incorporated in 2003 and headquartered at 826 Orange Avenue, Suite 633, in 92118, operates as a noncommercial research organization specializing in spinal biomechanics, whiplash traumatology, and motor-vehicle-crash injury analysis. The institute is led by Arthur Croft, PhD, DC, MSc, MPH, FACO, whose published research on cervical spine injury mechanisms has shaped diagnostic and medico-legal standards used by chiropractors, physicians, and expert witnesses nationally. Its flagship Whiplash and Brain Injury Traumatology certification program trains healthcare providers in crash-physics biomechanics, cervical diagnostics, and evidence-based post-collision treatment protocols — the same injury spectrum treated clinically by Back2Play-Coronado Chiropractor on Orange Avenue. The NAICS 541720 classification (Research and Development in the Social Sciences and Humanities) underscores the institute's role as an academic research body rather than a direct patient-care clinic. Practitioners completing the SRISD certification curriculum apply its protocols in spine-injury evaluation, medico-legal case analysis, and rehabilitation planning, with graduates practicing across the chiropractic and orthopedic communities including Coronado's own Potter Chiropractic on Orange Avenue. The Orange Avenue address places the institute's administrative office within Coronado's primary commercial corridor, adjacent to the island's concentration of medical and wellness practices.
