Irvine, CA 92618

I am a psychiatrist trained at NYMC and UCLA with a specialized focus in child, adolescent, and addiction psychiatry. My practice is dedicated to providing high-quality, individualized care to a select number of patients. With expertise in behavioral management for ADHD and Cognitive Behavioral Therapy (CBT) for anxiety and depression, I provide care for individuals from childhood through adulthood. I treat diverse pathologies including complex substance use and behavioral addictive disorders such as gaming, sex, and gambling disorders.

My approach combines evidence-based therapies with medication management, ensuring that each patient’s unique needs are addressed. Whether you’re facing the challenges of ADHD, anxiety, or depression, I offer compassionate support and effective strategies to help you achieve your highest level of functioning.

I provide care mainly via telehealth only and can be in-person for selected cases.
