Board-certified child, adolescent, and adult psychiatrist at 7946 Ivanhoe Ave, Suite 320, La Jolla, CA 92037. The building pairs Dr. Kornberg's pediatric psychiatry upstairs with Karen Zappone's adult psychotherapy downstairs — a vertical split that lets families manage cross-generational mental health treatment without leaving one Ivanhoe address. Dr. Kornberg earned his MD from George Washington University School of Medicine in 2005, completed his general psychiatry residency at Montefiore/Albert Einstein in New York, and returned to San Diego for a child and adolescent fellowship at UCSD/Rady Children's Hospital. He holds dual board certification from the American Board of Psychiatry and Neurology, is affiliated with Sharp Memorial and Sharp Mesa Vista hospitals, and speaks Spanish. Where Kornberg's insurance-panel model serves families at standard copay rates, Donna Kashani, M.D. on Executive Square runs a concierge practice with direct cell-phone scheduling and no retainer — two fundamentally different access models for child and adolescent psychiatry in the same zip code.
