What we treat

What does a psychiatrist in Hamilton treat?

A psychiatrist is a medical professional who diagnoses and treats mental health conditions and can prescribe and monitor medication. At our Hamilton office, psychiatric care is the foundation of a whole-person plan: a full medical and psychological evaluation, a clear diagnosis and coordination with therapy and other support. Many of our Mercer County patients juggle shift work, school schedules and daily drives on I-295 or the Turnpike, so we start with your symptoms, history and goals and build a plan that fits your week. Then we adjust it as you improve.

Depression

When sadness, fatigue or a loss of interest start to weigh on work and home life, we begin with a full evaluation and use medication only if it suits your plan.Depression treatment in Hamilton →

How it works

How do I start psychiatric care in Hamilton?

Book your visit

Request a time online or call 1 (877) 803-5342. After that, pick an in-person visit at Horizon Center or a secure video appointment.

Psychiatric evaluation

Your clinician asks about your symptoms, sleep, stress, medical and family history, then explains what they think is going on in plain, everyday language.

Plan & follow-up

Together you agree on a plan and a first step. Follow-up visits, in person or by video, track your progress so the plan can change early if needed.
