One Agency. One Vision. Many Goals. 


Mission Statement:

The Mental Health Association of Nassau County (MHANC) is a 501(c)(3) not-for-profit membership organization dedicated to improving mental health in our community through advocacy, education, program development and the delivery of direct services.


Our Philosophy

MHANC believes mental health is as important as physical health, and that recovery is possible. Our services assist individuals facing chronic and serious mental illness and psychiatric disabilities, supporting them on their paths to building productive and meaningful lives.



Since its founding in 1953, MHANC has been an advocate for the needs of adults and children with psychiatric and emotional difficulties.  Throughout the 1970’s, MHANC provided information for individuals seeking treatment or services while continuing its advocacy efforts.  In the 1980’s, the agency grew rapidly to fill the growing need for innovative community services.

During the course of the last 68 years, MHANC various accomplishments include opening:

  • Walden Corners: the first community residence for people with psychiatric disabilities on Long Island in 1983
  • The Terrace: the first children’s residence for children with autism in 1989
  • College Bound:-the first supported education program for college students in 1988
  • Clinton Court: the first permanent-home apartment complex for adults with psychiatric disabilities in 1998
  • Turquoise House: the first Peer-Run Respite on all of Long Island in 2015

These programs represent more than simply achievements; they signify innovations in raising the standards of excellence for programs and services for those with mental illnesses and developmental disabilities.


Our Impact

MHANC offers comprehensive services and advocacy that focuses on mental health, as well as overall health and wellness. The following are highlights from some of our programs in 2020:

    • PROS total direct care hours – 13,368 hours of direct care
    • Housing – 44,165 days of housing with support services
    • Education & Training – Provided workshops for more than 1,900 community members and professionals
    • Adults Receiving Financial Management – Supported 545 individuals
    • Veterans Services – Reached over 4,500 veterans on Long Island (the second largest population of veterans in the country)



The MHANC seeks to collaborate with other providers to continuously benefit the community.  We work with clinics in Nassau County, provide consultations to many school districts and coordinate advocacy on behalf of the mental health system. Our advocacy efforts include fighting discrimination laws and stigmatizing media messages, promoting the need for adequate funding for services and housing, and encouraging consumers to speak for themselves on personal and policy issues.
