About GMS

For over four decades, GMS has been designing and maintaining programs that enhance, support and teach through knowledge, respect and dignity.

We are dedicated to serving the community by providing a valuable service while working collaboratively with individuals served, guardians, family members, agencies, caseworkers and other advocates. The individuals we serve live, work, volunteer and socialize in their community with support from dedicated professionals.

GMS provides Shared Living, In-Home Support, Case Management, and Residential Services. Each of these departments is designed to assist and enable each of our consumers to accomplish and maintain their highest attainable living skills, and to improve their quality of life by supporting independence.

GMS has been recognized as the best of its kind and is growing at a steady pace despite a turbulent financial climate. With this growth, we are able to offer a variety of services to meet the specific needs of each individual. Our focus is on quality individualized programming that fosters choice, independence, community integration and the ability to learn new skills as well as build upon present ones. Call or email us today and find out why GMS has become one of Maine’s premier providers of developmental services.
