New members are always welcome and wanted. The only requirement is an interest in local history.
Why Join?
The Mastic Peninsula Historical Society is made up of community volunteers who share a love of local history and a desire to preserve it for future generations.
We are a not-for-profit organization that runs entirely on membership dues, donations, and the dedication of our volunteers. Every member makes a difference.
There are no special qualifications. If you care about the history of Moriches, Mastic, Shirley, or Long Island's South Shore, you belong with us.
