Teresa Key, PhD in Encinitas is a Scripps-affiliated clinical psychologist practicing on Manchester Avenue in Cardiff-by-the-Sea, treating adults for conditions including seasonal affective disorder and mood-related presentations. Her office near San Elijo Lagoon provides in-person individual psychotherapy, and her dual-location model with a La Jolla office extends her reach across San Diego County's coastal corridor, a geographic range shared by the Cardiff-based practitioners at Gold Coast Chiropractic. Dr. Key accepts Medicare and maintains enrollment with the Centers for Medicare and Medicaid Services, making her one of a limited number of doctoral-level psychologists in the 92024 ZIP code participating in the federal program. Her clinical scope encompasses the full range of adult mood, anxiety, and adjustment disorders, with treatment informed by the longitudinal therapeutic relationships that characterize private-practice psychology. Integrative wellness coordination for patients managing concurrent medical and psychological conditions connects her referral network to providers at Oasis Health and Medicine, where physician-supervised protocols address the physiological substrates of stress-related symptomatology. Complex cases involve extended psychotherapy for adults with treatment-resistant mood disorders requiring coordinated care across multiple medical specialties and concurrent pharmacological management.
