Trinity Services Endowment Fund

The Trinity Foundation and Trinity Services created the Trinity Services Endowment Fund to provide long-term financial stability for Trinity Services and the people served by the organization.

The Endowment Fund provides a permanent source of funding for Trinity Services.  The principle is invested wisely and preserved, while a portion of the earnings is used annually, providing predictable budget support.  The result is that your generous gift becomes ongoing and self-renewing.
