Holding a doctorate in clinical psychology, Colgan Sharon M PhD maintains a private practice at Lake Park Way in La Mesa's Grossmont corridor, providing psychotherapy and diagnostic assessment for adult clients. The practice's location near the Sharp Grossmont Hospital campus positions it within the same referral network as primary-care providers such as Health Ave Pediatrics, supporting integrated behavioral and medical care across the La Mesa health corridor. Telehealth sessions extend the practice's reach beyond the 91942 ZIP code, serving clients throughout San Diego County who require ongoing psychotherapeutic support without in-office visits. Clinical psychology's diagnostic scope includes structured psychological testing and evidence-based intervention planning, a complementary discipline to the neuromuscular assessment work performed at chiropractic practices like Acru Health - La Mesa for stress-related pain referrals. Comprehensive psychodiagnostic evaluations incorporate validated instruments including the MMPI-2, Beck Depression Inventory, and structured clinical interviews calibrated to DSM-5-TR classification criteria.
