Board-certified in both adult psychiatry and child and adolescent psychiatry, Dr. Eric Mustonen, MD treats patients in San Diego's Allied Gardens neighborhood at the Kaiser Permanente Vandever Medical Offices, 4405 Vandever Ave, 92120. He earned his medical degree from New York Medical College in 1975 and completed a psychiatry residency at UC San Diego Medical Center from 1976 to 1978, followed by a child and adolescent psychiatry fellowship at the same institution from 1978 to 1980. That dual certification allows him to manage psychiatric conditions across a patient's full lifespan, from pediatric-onset ADHD and anxiety disorders through adult-onset mood and psychotic conditions, within the same integrated-care system as Kaiser Permanente Vandever Medical Offices primary-care physicians who coordinate referrals under one roof. Dr. Mustonen's hospital affiliations include Kaiser Foundation Hospitals, Children's Hospital and Health Center, Alvarado Hospital Medical Center, and Sharp Mesa Vista Hospital, giving him inpatient privileges across multiple psychiatric and pediatric settings. His UCSD fellowship training anchors a clinical approach that integrates medication management with psychotherapeutic evaluation for minors, an area where Kaiser's behavioral health division runs a distinct caseload from independent outpatient practices such as Alter Behavioral Health in the broader College Area zone. The Allied Gardens office sits along the Interstate 8 freeway corridor between Waring Road and Zion Avenue, a stretch anchored by the Kaiser Permanente Zion Medical Center campus roughly half a mile east. Patients schedule through Kaiser's centralized behavioral health intake at (619) 528-5000, the same line that routes to the department's psychiatric evaluation, group therapy, and crisis-intervention services.
