Kaiser Permanente's child and adolescent psychiatry division in Allied Gardens, San Diego, includes Dr. Brian Hendrickson at the 4647 Zion Avenue campus in the 92120 ZIP. Hendrickson holds board certification in both general Psychiatry and Child and Adolescent Psychiatry, a dual credential he built through a Georgetown University School of Medicine degree in 2013, a psychiatry residency at New York-Presbyterian Hospital's Cornell Campus where he served as Chief Resident, and a fellowship in Child and Adolescent Psychiatry at Johns Hopkins University completed in 2019. The Kaiser Permanente system routes Hendrickson's patients through primary care coordination at Kaiser Permanente Vandever Medical Offices in Allied Gardens, ensuring pediatric psychiatric care integrates with developmental screening and general health monitoring. That training pipeline — Georgetown, Cornell, Johns Hopkins — represents three of the top-ranked psychiatric programs in the country. Hendrickson's published research includes a review of cannabis use patterns among adolescents during the era of marijuana legalization and a case series on supplement-induced mania, work that directly informs his clinical approach to substance-related mood disruption in teenage patients. He is a member of the American Psychiatric Association, the American Academy of Child and Adolescent Psychiatry, and the American Academy of Psychiatry and the Law. Hendrickson treats ADHD, anxiety, autism spectrum presentations, eating disorders, conduct disorders, and PTSD in children and adolescents, applying medication management alongside therapeutic protocols. The Allied Gardens location on Zion Avenue serves families from across San Diego's eastern communities, including the residential neighborhoods along Waring Road and the I-8 corridor. When acute psychiatric crises arise outside Hendrickson's scheduled appointments, the Emergency Room at Kaiser Permanente Zion Medical Center on the same campus provides immediate triage with access to Hendrickson's treatment records. His adolescent-focused practice addresses the developmental window where early intervention most effectively redirects psychiatric trajectories.
