What we treat

What does a psychiatrist in Manhasset treat?

A psychiatrist is a medical professional who diagnoses and treats mental health conditions and can prescribe and monitor medication. On Northern Boulevard, our Manhasset clinicians start with a complete medical and psychological evaluation and a clear diagnosis, then join up medication, therapy and primary care in a single plan. North Shore patients often balance demanding careers, school pressure on their children and caring for parents, so we plan treatment around those realities.
