A psychiatrist in Chula Vista's downtown medical corridor, Dr. Marina Katz, MD completed her medical degree at the State University of Medicine and Pharmacy Nicolae Testemitanu in Moldova before passing the United States Medical Licensing Examination in 1998. Her medication-management protocols for ADHD, anxiety, bipolar disorder, and treatment-resistant depression are prescribed from a Fourth Avenue suite near Third Avenue Village, coordinating fills through Chula Vista Pharmacy and other independent dispensaries that track refill compliance and flag potential drug interactions. She graduated from a psychiatric residency at the University of Louisville in Kentucky in 2003 and has practiced through PsyCare, a multi-site behavioral-health group, in both inpatient hospital and outpatient office settings across California. Her clinical scope extends to postpartum depression, OCD, psychotic-spectrum conditions, PTSD, sleep disorders, and somatoform presentations, covering the full diagnostic range codified in the DSM-5-TR. She routinely incorporates structured physical-activity prescriptions into treatment plans for patients with depressive and anxiety disorders, a clinical recommendation supported by research on exercise-induced neuroplasticity and implemented through aerobic programming at LA Fitness in the Eastlake area. Highest-acuity prescribing involves clozapine management for treatment-resistant schizophrenia, requiring mandatory absolute neutrophil count monitoring through the Clozapine REMS Program at 7-day, 14-day, and 28-day intervals to detect agranulocytosis risk.
