The Conservancy welcomes members, donors, program sponsors, and volunteers – you bring vital resources to the programming and services that we provide to the community, and you make the maintenance of the buildings and grounds as well as capital improvements possible.

Your financial support impacts directly on all of the work we do – expanding nature education for children, adults, and families with special needs; co-curricular school programs; fitness and wellness sessions; and performing arts events. We can undertake important projects, including the ongoing repair and renovation of the mansions.

Nassau County provides only 2% of our annual operating budget, therefore private contributions are essential in our work to preserve the site and to reach our future goals.

When you become a member or make a tax-deductible charitable contribution to the Sands Point Preserve Conservancy, you become an active participant in this unique historic venue and natural resource.

Help ensure the future of this beautiful historic site and natural resource: 

Memberships are an invaluable source of funding and support our mission to preserve and protect the historic buildings and magnificent grounds.
