Following his residency, Dr. Thankachen worked in an adult outpatient setting at a county medical center before relocating to Orange County, California. He currently practices in both outpatient and inpatient psychiatric and medical settings, providing advanced and comprehensive mental health care.
Dr. Thankachen treats a wide range of psychiatric conditions, including depression, bipolar disorder, schizophrenia, anxiety, and dementia-related disorders. He remains actively involved in professional organizations, holding memberships in the American Psychiatric Association, Indian Medical Association, and Karnataka Medical Association.
With experience spanning a wide range of clinical settings—including outpatient clinics, inpatient detox and rehabilitation, psychiatric emergency care, and dual diagnosis programs—Sean specializes in treating substance use disorders, depression, anxiety, mood disorders, PTSD, ADHD, and OCD.
Although his primary focus is on adult populations, Sean has been trained to provide care across the lifespan, from children and adolescents to geriatric patients. His approach integrates medication management, crisis intervention, and psychotherapy, emphasizing a holistic and patient-centered model of care.
Sean firmly believes that “everyone can benefit from therapy, and many may also find significant improvement with medication. Therapy remains the cornerstone of my practice—whether or not medication is part of the treatment plan.”
