The Chamber of Commerce of the Mastics and Shirley was incorporated in 1951.
Our mission is: to enhance economic growth through the promotion and development of business for the betterment of our communities.
Annual community events managed by the Chamber include Halloween and Easter celebrations offered free to hundreds of children, and an annual recognition dinner honoring a local resident or organization who has had a lasting positive influence on our community. Our Chamber has the unique distinction of hosting the largest Christmas Parade in the Town of Brookhaven, with an average attendance of more than 6,000 onlookers and more than 80 groups and organizations marching. Our charitable work includes fundraising to offer scholarships to graduating seniors going on to pursue business studies in college and support of local civic and nonprofit events that benefit our residents.
