Choosing a mental health facility in Nassau County

Ask which conditions and age groups are served, whether medication management and psychiatry are available, how appointments and wait times work, and what insurance or payment is accepted. These listings are unrated - verify services, licensing, cost, and availability directly.

Compare providers on the care they deliver, not on a ranking. Look at the levels of care offered, whether medications for opioid use disorder are available, the populations served, payment and insurance options, and the current licensing status of each program.

When you are choosing for yourself or someone you care for in Nassau County, call ahead to confirm current availability, intake requirements, accepted insurance or payment, and whether the program is licensed or certified. Ask what happens if someone needs a higher or lower level of care.
