Dr. Ekaterina Vassilenko, MD is a board-certified child, adolescent, and adult psychiatrist in Bonita who earned her medical degree at the Novosibirsk Medical Institute in Russia before completing a psychiatry residency at UCLA and the VA Greater Los Angeles Healthcare System. Her fellowship in child and adolescent psychiatry at Cedars-Sinai Medical Center refined diagnostic skills for early-onset mood and anxiety disorders, a subspecialty that interfaces with integrative providers along the Bonita corridor including Bonita Acupuncture Clinic for patients incorporating complementary stress-reduction protocols. Practicing through PsyCare from the Otay Lakes Road office in the 91902 ZIP, she conducts psychiatric evaluations and medication management in English and Russian for patients across the Bonita and greater Chula Vista communities. Her clinical scope covers attention-deficit/hyperactivity disorder, depressive spectrum conditions, anxiety disorders, and behavioral disruptions in children through adults, with pharmacological interventions tailored through close monitoring of therapeutic response and side-effect profiles. That emphasis on neurochemical balance extends to her advocacy for movement-based adjunctive therapy, a clinical recommendation aligned with structured Reformer-based programming at Club Pilates Bonita on the Bonita Road corridor near Bonita Golf Club. Cross-titration protocols for pediatric patients phase one psychotropic agent out while introducing another, monitoring plasma half-life overlap windows to prevent withdrawal and rebound effects simultaneously.
