Tri-Town Youth Services is funded through the State Department of Education, municipal allocations, and a number of miscellaneous grants. The agency also relies on fundraising events, program fees, and donations from civic clubs, business, the faith community, and the private sector.

Through the Middlesex County Community Foundation, George W. Whelen IV has set up a designated fund for Tri-Town Youth Services to help secure the future of the organization. Tri-Town is also a participant in Leave a Legacy in Connecticut.
