Donate to the Sunmark Charitable Community Foundation

Sunmark has a long history of giving within the Capital Region since its beginning as a small credit union within General Electric in 1937. As Sunmark has grown to one of the largest credit unions in the area, so too has its giving grown. The Sunmark Foundation now supports local, nonprofit organizations by providing financial contributions, in-kind services, and volunteer support.
