Board-certified in both psychiatry and neurology, Ana Andia, MD, practices through Kaiser Permanente in Allied Gardens, San Diego, from the medical campus at 4647 Zion Avenue. Andia earned her medical degree from the University of Texas Medical School at Houston in 1985 and completed dual residencies at UC San Diego Medical Center — Internal Medicine from 1984 to 1987 and Psychiatry from 1987 to 1990 — giving her a cross-disciplinary foundation that most psychiatrists in the 92120 ZIP do not carry. That internal medicine background allows Andia to evaluate psychiatric symptoms against medical differentials, distinguishing anxiety from thyroid dysfunction or depression from neurological conditions with clinical precision. Her Zion Avenue office operates within the broader Kaiser Permanente Zion Medical Center campus, which provides integrated access to laboratory services, imaging, and specialist referrals under one roof. Andia has published peer-reviewed research on gender differences in schizophrenia and on trazodone-fluoxetine combination therapy for obsessive-compulsive disorder, contributing to the evidence base that informs her prescribing decisions. Her 41 years of medical experience span the full diagnostic spectrum from ADHD and bipolar disorder through treatment-resistant depression and psychotic disorders. The Allied Gardens location sits along Zion Avenue between Waring Road and the Interstate 8 corridor, serving the residential communities of Allied Gardens, Grantville, and Del Cerro. Kaiser members filling psychiatric prescriptions written by Andia can process them at the on-system Pharmacy at Kaiser Permanente Vandever Medical Offices in Allied Gardens, keeping medication management within the integrated care record. Andia's neurology co-certification positions her to manage cases where psychiatric and neurological presentations overlap, including seizure-related mood disturbance and post-concussive depression.
