The five Kirschner Trusts have supported charitable projects in the Muskogee area since 1979. In 2013, the assets of three of the Kirschner Trusts were transferred to the Oklahoma City Community Foundation to establish the E. Phil and Roberta Kirschner Foundation Affiliated Fund.
Grants are awarded to nonprofit organizations that provide direct services in the following categories, with a preference for programs in Muskogee and the surrounding area:
- Social services
- Youth and education
- Health and disabilities
- Jewish religion and culture
