Your generous support helps fund our mission driven programs and the work we do at the Emerson Brook Forest Outdoor Center.

With the completion of our 1200 sq. ft. timber frame in 2024, TSP moved into a new realm of possibility. During 2025 we held our first retreat in collaboration with Aloha Yoga and hosted 3 art exhibits in the building along with a collection of more than 150 Clay Head sculptures by the late artist, Susan O’Hara. Our final exhibit of the year included the combined work of 18 local artists. With the help of 40 volunteers, we opened up a .6 mile hiking trail, created a fire circle and completed several of TSP’s forest management goals. 

In 2026 we plan to grow our organizational capacity in order to increase and diversify our program offerings, which will include expanding the rental of our beautiful space for retreats, meditations, and workshops that align with TSP’s mission and values.
