In 1966, John Philip Greenwell, Jr. established Greenwell Foundation and began long-term plans for his Southern Maryland estate, and the park opened to the public in the mid-1990s. In 1997, Greenwell Foundation began offering active programs. Greenwell Foundation, Inc. is a nonprofit organization with a mission to provide educational, therapeutic and recreational programs for people with and without disabilities in a natural environment at Greenwell State Park. The foundation operates Equestrian, Nature, Veterans, and Summer Camp programs and provides outdoor nature connection and therapeutic, environmental and recreational programs for veterans, active military, military families and all people with and without disabilities. Foundational program areas are the Equestrian, Nature Connection and Outdoor Programs for children and adults with intellectual, developmental and physical disabilities.
Current programs targeted towards veterans and active military include charter boat fishing trips where up to 16 veterans spend a half day on the water with lunch and all equipment provided, as well as trail rides, sessions of Equine Assisted Activities and Therapies for local veterans, and kayak fishing tours. Activities are often linked with volunteer opportunities, since veteran participants want to give back to the organization and be served by it. The Greenwell Foundation Therapeutic Retreat Project features longer, eventually overnight, stays and reflective time that is facilitated by a therapist.
Greenwell Foundation operates through an innovative partnership with the Maryland Department of Natural Resources, which provides the foundation rent-free use of all park facilities and a substantial manpower contribution towards the overall upkeep of the park. Annually, more than 60,000 people visit the park. Greenwell Foundation currently serves individuals from St. Mary’s, Calvert, and Charles counties, as well as from Prince George’s County and Washington, D.C. Greenwell Foundation is funded solely by program fees, donations, sponsorships, grants and gifts and receives no financial support from the state of Maryland or any agency thereof including the Maryland Park Service or the Department of Natural Resources, and every effort is made to keep program fees as low as possible so that everyone may participate without creating a financial burden. The foundation serves the needs of the community by offering inclusive programs to individuals, families, centers and businesses.
The leadership team includes Executive Director Maria McDonald, Deputy Director Janene Stocking, Equestrian Program Director Melisa Kennedy, Summer Camp & Nature Director Ally Rodgers, Advancement Director, Veterans & First Responders Program Christopher Davies, Marketing Director Keyarra Pratley, Office Manager & Program Assistant Connie Sperling, Equestrian Volunteer Coordinator Janis Clifton, Operations Assistant Jess Fender, Education Consultant Leigh Deane, Bookkeeper Joy Myers, Community Coordinator Ashlyn Conley, and Nature Program Support & Summer Camp Counselor Joanna Cleaver, with Development listed as a position available. The Greenwell Foundation Board of Trustees includes Dennis England, President; John F. Tarrant, Esq., Vice President; Jane Tyson, Treasurer; Frannie Bostich, Secretary; and members Joe Anderson, Teri Branch, Mark Duval, Usha Iswara, Kathryn Kopanke, Dr. Janine Wert, and Bob Randall.
