Occupational medicine in downtown San Diego's Bankers Hill draws on the board-certified expertise of Lorentz John F MD, who completed residency in public health and general preventive medicine through the joint UCSD–San Diego State University program in 1996. Workplace injury evaluations cover OSHA-mandated assessments, DOT and FMCSA physical examinations, and return-to-work clearance protocols, with musculoskeletal rehabilitation cases referred to Spine & Sport Physical Therapy in the Gaslamp Quarter for structured recovery. University of South Carolina School of Medicine conferred his medical degree in 1985, and an internal medicine internship at Providence St. Vincent Hospital in Portland preceded the transition into preventive and occupational specialization on Fourth Avenue near Balboa Park. Repetitive strain evaluations, industrial ergonomic assessments, and workers' compensation impairment ratings round out the diagnostic scope, running parallel to the spinal injury rehabilitation work at Bayside Spine & Sport along the downtown waterfront. Highest-complexity services involve impairment evaluations under the AMA Guides to the Evaluation of Permanent Impairment with California Division of Workers' Compensation apportionment methodology for disputed permanent disability determinations.
