The Martens Family Foundation concentrates its giving on local faith-based organizations and community philanthropy, with the bulk of support directed to Lutheran congregations and a Lutheran school in the Twin Falls area. Grants are typically unrestricted (“general use”), suggesting a preference for flexible operating support rather than project-specific funding. The foundation also channels significant funds to another foundation-like entity (JAE Foundation), indicating a role in supporting philanthropic infrastructure or partner grantmaking. Overall, their philanthropy is local, faith-centered, and operationally focused.
Concentrated and repeat-focused: a small number of relatively large, unrestricted grants, often repeated to the same recipients; geographically local and primarily faith-based grantees.
Immanuel Lutheran Church, Xrossway Lutheran Ministries, Clover Trinity Lutheran School, JAE Foundation
A defining feature of Martens Family Foundation Inc is its repeated support for the local Lutheran network around Twin Falls. In the recent grants list, Immanuel Lutheran Church appears in multiple years, alongside Xrossway Lutheran Ministries and Trinity Lutheran Church in Eden, all funded for general use. The foundation also backs a local philanthropic intermediary, Jae Foundation, with some of the largest awards in the file, suggesting a sustained relationship with partner-led giving. Smaller grants extend the same local pattern into a school, a church camp, youth-serving organizations, and a few broader community groups, all within a tightly local footprint. The foundation’s grants are generally flexible rather than project-restricted, which points to operating support as a core part of its approach. That pattern is visible across faith-based recipients and community organizations alike. Clover Trinity Lutheran School in Buhl, Camp Perkins Lutheran Ministries in Ketchum, Twin Falls County 4-H FFA, and Boys & Girls Clubs in Twin Falls all received general-use support in the recent record. The overall picture is of a foundation that funds a close set of Idaho institutions, with faith communities at the center and local civic and educational organizations included around them.
Faith-based giving is the clearest theme in the record. Martens Family Foundation Inc gave $24,690 to Xrossway Lutheran Ministries in Twin Falls for general use and $5,000 to Trinity Lutheran Church in Eden for general use, alongside repeated support to Immanuel Lutheran Church. Education and youth development also appear in the grant list. The foundation awarded $7,000 to Clover Trinity Lutheran School in Buhl for general use and $1,400 to College of Southern Idaho Fndn Inc in Twin Falls for general use. Its community support reaches beyond churches and schools. In 2025, it gave $2,934 to Twin Falls County 4-H FFA and $1,200 to Boys & Girls Clubs in Twin Falls, both for general use, while also making general-use grants to Idaho Humane Society and Rising Stars Therapeutic Riding Ctr.
Typical grant size is modest: p25 is $500, the median is $1,750, and p75 is $5,000. The recent record shows a mix of one-off and recurring support, with several recipients appearing in multiple years, including Immanuel Lutheran Church, Jae Foundation, Trinity Lutheran Church, Camp Perkins Lom Inc, Twin Falls County 4-H FFA, and Idaho Humane Society. Grants are consistently described as general use, indicating flexible support rather than tightly restricted project funding. The foundation does not fund individuals and does not make program-related investments.
