A note from our CEO and
Medical Director
Welcome to The California Neuropsychiatric Institute. We provide compassionate, research-informed psychiatric care for patients with complex and treatment-resistant conditions.
I established CNI to expand access to advanced treatment options, including Spravato®, TMS therapy, diagnostic assessment, and clinical trial participation. Our goal is to personalize care, improve outcomes, and help patients move toward meaningful, sustainable improvement.

CNI provides specialized psychiatric treatment, advanced diagnostic assessment, clinical trial access, and forensic consultation for patients and referral partners seeking a higher level of expertise.

Spravato® Treatment

Clinical Trials

Psychiatric & Diagnostic Assessments
Comprehensive psychiatric evaluation, medication management, ADHD testing, diagnostic clarification, neurocognitive screening, and treatment planning tailored to each patient's symptoms, history, and goals.

Forensic / Litigation Psychiatry
