Psychologist Russell W. Dehnel, Ph.D. maintains a San Diego practice at Alliance Health Clinic on El Cajon Boulevard in the College Area 92115 ZIP, holding California psychology license #PSY 12603 and NPI 1346526274. His clinical career spans more than four decades of psychological practice, and his office at 5952 El Cajon Boulevard sits within a shared medical complex alongside City Heights Family Health Center's broader network of community health services, embedding behavioral health within a primary care ecosystem for College Area and adjacent neighborhoods. The El Cajon Boulevard corridor runs east from SDSU toward the Grantville border, drawing a client base from the campus community and the surrounding residential neighborhoods. Dehnel is enrolled in the County of San Diego Behavioral Health Services fee-for-service provider network, accepting Medi-Cal and Medicare referrals for psychological assessment and treatment. His clinical scope covers depression, anxiety, adjustment disorders, and psychological evaluations, with a practice model rooted in the community mental health tradition that prioritizes access for publicly covered and self-pay clients. The El Cajon Boulevard commercial strip between College Avenue and 60th Street concentrates medical, social service, and behavioral health providers, and integrative practitioners at Armonía Integrative Medicine in College Area offer combined conventional and complementary treatment approaches for patients in the same corridor. Dehnel's Medicare participation status allows him to accept assignment, meaning the approved amount for covered psychological services serves as payment in full with no balance billing to the patient.
