Dr. Lindsay O'Shea in Encinitas's Cardiff-by-the-Sea is a clinical psychologist specializing in child, adolescent, and parent therapy through SoCal Psychological Solutions P.C. on Newcastle Avenue. Clinical treatment plans for ADHD and childhood anxiety incorporate parent coaching, attachment-based intervention, and psychoeducational testing — a multi-modal approach that complements developmental pediatric monitoring at Children's Primary Care Medical Group. The practice maintains concurrent active licensure in California, Colorado, and Utah, enabling cross-state telehealth continuity for relocating families. Family systems work targeting co-regulation strategies with neurodivergent children distinguishes the clinical model from generalist therapy, operating along the same Cardiff corridor that includes The Nurture Collective for pediatric chiropractic support. Designated as women-owned and LGBTQ+ affirming with transgender-safespace clinical protocols, the office provides wheelchair-accessible facilities near San Elijo State Beach. Highest-complexity cases involve multi-session psychological assessment batteries evaluating executive function deficits, emotional regulation capacity, and attachment security patterns across standardized diagnostic instruments.
