Greater Nashua Mental Health is the non-profit, state-designated Community Mental Health Center serving primarily the Greater Nashua Region, a densely-populated area with an abundant need for services, a need that is increasing, especially with the opioid epidemic which has gripped our state as well as the nation.  We primarily serve residents of Amherst, Brookline, Hollis, Hudson, Litchfield, Mason, Merrimack, Milford, Mont Vernon and Nashua.

GNMH accepts most insurance plans as well as Medicaid and Medicare. For those without insurance coverage, the agency offers a sliding fee scale based upon family size and income. No one is ever turned away due to the inability to pay for services. The agency provides services without discrimination and welcomes all who need care.
