Mac loved serving in the church and in his community. After his cancer treatment over 20 years ago, he established a foundation to help families that had children with cancer. After he had turned the foundation over to a group to run it and just before he died, the foundation was renamed Mac's Gift. At the funeral the families and children that were helped by the foundation lined the sidewalk and as the family followed the coffin to the hearse they sang "I Am a Child of God". Mac served as a BYU Student Ward Bishop, a counselor in a Stake Presidency, MTC Bishop and Patriarch.
