Alternative medicine in San Diego's Normal Heights takes a root-cause diagnostic approach at Dr. Donald C. Clark's practice, located at 3504 Adams Avenue in the 92116 ZIP. The office occupies a storefront on the Adams Avenue stretch between 35th Street and Kensington Drive, the independent-business cluster that defines this section of Normal Heights. Clark's practice covers non-pharmaceutical therapeutic approaches including applied kinesiology, nutritional assessment, and manual soft-tissue techniques designed to identify functional imbalances that standard lab panels may not flag. Hormonal-health cases share therapeutic territory with the midwifery and bioidentical-hormone work at Karly Nuttall Midwifery & Hormone Health, whose endocrine-focused protocols complement Clark's nutritional and manual approaches. The diagnostic process uses muscle-testing protocols and reflex-point assessment to map organ-system stress before designing supplement and dietary intervention plans. Autoimmune flare management, digestive dysfunction, adrenal-stress patterns, and environmental-sensitivity syndromes each receive individualized evaluation. The Adams Avenue address sits six blocks west of the Kensington-Normal Heights Branch Library and within the commercial zone that fills with foot traffic during the annual Adams Avenue Street Fair and Adams Avenue Unplugged music events. Clark's treatment room runs wheelchair-accessible entry, dedicated parking, and a restroom on-site. Rehabilitation patients whose alternative-medicine plans include movement-based recovery add physical therapy at RISE Physical Therapy across the border in North Park, a short walk west on Adams Avenue. Detoxification and elimination-diet protocols follow structured 21- to 30-day timelines with weekly check-ins to track symptom resolution against baseline intake data.
