The MACC Fund is dedicated to funding childhood cancer and related blood disorder research.
Midwest Athletes Against Childhood Cancer Inc puts pediatric cancer and related blood disorder research at the center of its grantmaking, with a recent $3.75 million award to The Medical College of Wisconsin Inc anchoring the pattern. The foundation’s support is built around research, not individual aid, and it backs work meant to improve treatments and move discoveries toward care for children. Recent grants also include $2 million to the University of Wisconsin Foundation and $1.45 million to the Board of Regents of the University of Wisconsin, showing a strong focus on university-linked research infrastructure in Wisconsin. Its funding has repeatedly supported medical colleges, hospitals, and cancer centers that conduct translational pediatric oncology work. The MACC Fund’s active grant programs point to a sustained emphasis on investigator-initiated projects, pilot studies, clinical trials, and capacity-building for pediatric oncology research. Across the recent grants list, the recipients are Wisconsin institutions in Milwaukee, Madison, Marshfield, and other parts of the state, which fits the funder’s local geographic scope. The organization’s leadership is listed as Rebecca Pinter, and its annual grants total $11,232,552.
A major part of the MACC Fund’s work is institutional research support. It gave $1.7 million to the Medical College of Wisconsin for pediatric cancer and related blood disorders research conducted in the MACC Fund Research Center. Another research-centered award went to Children’s Wisconsin, where a $1 million grant supported translational pediatric cancer and blood disorder research in the MACC Fund Center. The foundation also backs clinical trial participation: Marshfield Clinic received $50,000 for Children’s Oncology Group trials in pediatric hematology and oncology. Beyond those examples, the funder’s active programs name investigator-initiated research, pilot projects, translational work, and capacity-building as supported activities. Its taxonomy also includes pediatric oncology research, translational biomedical research, and family support resources for pediatric patients, showing a disease-specific portfolio tied to research and care improvements.
Grant sizes are large and highly concentrated. The typical award sits at a median of $1 million, with a first quartile of $461,914 and a third quartile of $1,187,500. The recent grants list shows repeat support over multiple years to the same Wisconsin institutions, including The Medical College of Wisconsin Inc, the University of Wisconsin system, Children’s Hospital of Wisconsin Inc, and Marshfield Clinic Inc. That pattern fits a recurring institutional grantmaking model rather than one-off individual awards. The foundation is structured as a nonprofit funder and does not fund individuals. Several active programs also note unsolicited applications are accepted for some research funding streams.
