The Greenwell Foundation is an independent entity, and is funded solely by program fees, donations, sponsorships, rental revenue, grants and gifts. The Foundation receives no financial support from the state of Maryland, or agency thereof including the Maryland Park Service or the Department of Natural Resources.

The Greenwell Foundation’s funding comes from a number of sources including the St. Mary’s County Commissioners, the United Way, grants, private philanthropy organizations, supporters, and members. A significant portion our operating budget is generated by program fees. Every effort is made to keep program fees as low as possible so that everyone may participate without creating a financial burden for them.

The Greenwell Foundation also works with a variety of organizations to obtain scholarships for program participants. These sources include the local ARC, the Department of Social Services, the Maryland Governor’s Office on Children, the SMECO Employee Contribution Committee, Special Olympics, Megan Mann Motorsports, Tidewater Dental, and Dr. Tim Modic through Smiles for Life and the Garth Brooks Foundation.

An innovative partnership between the Maryland Department of Natural Resources and the Greenwell Foundation provides the Foundation rent-free use of all park facilities and a substantial manpower contribution towards the overall upkeep of the park.
