Pacific Coast Injury Network operates a State of California registered Chiropractic Referral Service from its Cardiff-by-the-Sea headquarters on Chesterfield Drive in Encinitas's Cardiff district. Founded in 2012, the network coordinates personal injury chiropractic care across California for auto accident, workplace, and sports-related spinal injuries, referring complex cases to primary care physicians such as Keven Tagdiri, M.D. for concurrent medical management. Member chiropractors include former presidents of the San Diego Chapter of the California Chiropractic Association and recipients of the San Diego County Chiropractic Society's Doctor of the Year distinction, with providers holding up to thirty years of clinical experience. The network operates on medical lien with personal injury attorneys, providing whiplash treatment, spinal rehabilitation, and MedX-based spine strengthening at affiliated locations throughout the state. Musculoskeletal cases involving autoimmune or inflammatory joint components are co-evaluated with rheumatology specialists such as Natalie MacLean Rheumatology to differentiate traumatic from systemic pathology. Highest-complexity auto injury cases involve multi-phase cervical and lumbar rehabilitation using MedX isolated lumbar-extension and cervical-extension machines for objective strength-deficit documentation in medico-legal reporting.
