The Mark and Mary Ann Miller Family Foundation concentrates its giving on faith-based ministry in the Houston area and on contemporary arts education for youth, with occasional support for outdoor accessibility projects. A large portion of funding goes to a single local congregation (Christ the King Presbyterian), while the Contemporary Arts Museum Houston is a repeat arts-education recipient; a smaller gift to Glacier National Park shows occasional interest in conservation/accessibility.
A defining feature of the Mark and Mary Ann Miller Family Foundation is its repeated support for Christ the King Presbyterian in Houston, which received the foundation’s largest recent grants, including $70,500 in 2023, $60,000 in 2024, and $65,550 in 2025. That pattern sits alongside another steady line of giving to Contemporary Arts Museum Houston, where the foundation has backed teen-focused programming and general operations. The result is a profile shaped by local faith-based support and youth arts education, with additional smaller grants reaching parks, food assistance, and community organizations. The foundation’s recent activity also shows some flexibility in what it funds. In addition to church and arts grants, it supported Camp Blessing, Houston Food Bank, World Central Kitchen, and the Houston Arboretum & Nature Center. A 2025 grant to Glacier National Park Conservancy for Trail of the Cedars accessibility points to occasional interest in outdoor access and stewardship. Across these gifts, the foundation appears to favor general support and program support, often through relatively modest awards rather than highly restricted project funding.
Faith-based congregational support is a core part of the foundation’s giving. Christ the King Presbyterian in Houston received multiple general-budget grants, including $70,500 in 2023 and $60,000 in 2024, showing a sustained relationship with one local church. Youth arts education is another clear theme. Contemporary Arts Museum Houston received $22,500 in 2023 for teen education programming and general budget support, followed by $20,000 in 2024 for the same purpose. In 2025, the museum also received a grant that included Teen Council support. The foundation also funds community and public-service work. Houston Food Bank received $5,000 in 2023 for food provision, while PTSD Foundation of America received $2,500 in 2023 for general budget help serving vets with PTSD. Smaller gifts also reached Houston Arboretum & Nature Center and Houston Freedmen's Town Conservancy Inc for general support.
Typical grants are small to mid-sized: the 25th percentile is $2,500, the median is $4,000, and the 75th percentile is $12,500. The recent record shows both recurring and one-off support. Christ the King Presbyterian and Contemporary Arts Museum Houston appear across multiple years, while several other grants are single-year gifts. The foundation is a family foundation, gives program support and general support, and does not fund individuals. Its giving is local in scope, with most grants going to Texas recipients.

Concentrated and selective: few, relatively large grants with repeat funding to a small set of grantees; primarily local/Houston-focused with occasional one-off national gifts.
Notable grantees: Christ the King Presbyterian (Houston), Contemporary Arts Museum Houston, Glacier National Park Conservancy
The foundation’s giving is heavily concentrated in Texas, which accounts for 80% of grants and is also the top state by grant count. Houston is the main city in the portfolio, with repeated grants to organizations such as Christ the King Presbyterian, Contemporary Arts Museum Houston, Houston Food Bank, and Houston Arboretum & Nature Center. Outside Texas, the foundation made grants to Columbia Falls, Montana, and to Cookeville, Tennessee, but those appear less often than the Texas awards.
Recent grants show support for a Houston church, a contemporary arts museum, youth-serving organizations, food assistance groups, and park accessibility projects. Examples include Christ the King Presbyterian, Contemporary Arts Museum Houston, Houston Food Bank, and Glacier National Park Conservancy.
The grant-size distribution is small to mid-sized: p25 is $2,500, median grant size is $4,000, and p75 is $12,500. Many recent awards cluster at $2,500, $5,000, and $15,000, with a few larger gifts to recurring grantees.
Yes, but most grants go to Texas. The recent record also includes grants to Glacier National Park Conservancy in Columbia Falls, Montana, and Reformed Youth Ministries in Cookeville, Tennessee.
Yes. Christ the King Presbyterian appears in 2023, 2024, and 2025, and Contemporary Arts Museum Houston appears in 2023, 2024, and 2025. Those repeated awards suggest ongoing relationships rather than one-time gifts.
The recent grants frequently use broad support language such as general support, general budget, or general fund. Some are more specific, including Teen Council support at Contemporary Arts Museum Houston and Trail of the Cedars accessibility at Glacier National Park Conservancy.
