Ronnie & Cathy Matthews Great American Foundation

Greater Houston Community Foundation

Houston, TX

The Foundation makes grants through donor-advised and other donor-established funds for public benefit, human services, education, and health, including initiatives addressing economic mobility and poverty in Harris County. In 2024, its median grant was $25,000; it serves Greater Houston, while grants also go to recipients elsewhere in Texas and beyond. It does not accept proposals for the upcoming High-Impact Grantmaking cycle and plans to invite selected organizations or collaboratives to apply.

The Arena Energy Foundation

The Woodlands, TX

The Arena Energy Foundation supports a range of charitable causes, including senior services, child advocacy, youth programs, and services for people with disabilities; most 2025 funding went to Texas, with grants also in California, Louisiana, and New York. Its 34 grants ranged from $52 to $50,000, with a median of $5,000. It funds only preselected organizations and does not accept unsolicited requests.

Enterprise Holdings Foundation

Saint Louis, MO

The Enterprise Holdings Foundation supports charitable and educational nonprofits in communities where Enterprise Mobility operates, focusing on health, education, arts, and disaster relief; applicants must be actively supported by an Enterprise Mobility team member, spouse, or domestic partner. Giving varies widely: it reported 9,499 grants in 2024, but its 2025 filing showed one grant of $101.4 million, so that amount is not a typical award. Applications are accepted at any time through eligible Enterprise-affiliated applicants; the Foundation does not limit giving to preselected organizations.
