Certified Chiropractic Sports Practitioner and Qualified Medical Evaluator Dr. Gary Mcdowell has operated McDowell Family Chiropractic from University Avenue in La Mesa Village since 1989, holding degrees from Palmer College of Chiropractic and Michigan State University. The multidisciplinary clinic's five-thousand-patient treatment history spans pregnancy care, nutritional counseling, cold laser therapy, and sports-injury rehabilitation, with vision-related headache and postural-strain referrals coordinated through La Mesa Optometry for differential diagnosis. QME certification qualifies the practice to perform independent medical evaluations under California Division of Workers' Compensation protocols, generating impairment ratings and causation opinions for injured workers across San Diego County. Grappling and striking athletes from combat-sport academies including Gracie Jiu Jitsu La Mesa receive sport-specific spinal screening for cervical instability and rotational hip dysfunction common to ground-based martial arts. Highest-tier compliance protocols include California Labor Code Section 4060 QME examination documentation, AMA Guides to the Evaluation of Permanent Impairment Sixth Edition rating methodology, and Title 8 CCR Section 49 reporting standards for disputed workers' compensation claims.
