Meet Sean Thomas

Psychiatric Nurse Practitioner and I believe your mental health care is a partnership with you and your provider;
Hi, I'm Sean Thomas, a board-certified Psychiatric Mental Health Nurse Practitioner based in Smithtown, NY. With over a decade of experience in mental health care, I'm committed to helping patients achieve their best mental well-being.

I hold a Master's in Mental Health Psychiatric Nursing from SUNY at Stony Brook and a Bachelor's in Nursing. My background also includes a degree in Psychology. Over the years, I've had the honor of being on the Dean’s List multiple times.

Currently, I work at Mountainside Addiction Treatment Center, where I conduct psychiatric evaluations and manage medications. My role involves working closely with an interdisciplinary team to provide holistic care. At Family Service League, I have provided similar services, focusing on both adolescents and adults struggling with mental health and substance abuse issues.

I'm dedicated to offering personalized care and making a real difference in my patients' lives. Whether it's through evaluations, medication management, or treatment referrals, my goal is to support your journey to better mental health.

I'm here to help, and I look forward to working with you.
