At ten, his Cincinnati home was adjacent to the nation’s largest urban forest, where uncovering crawdads in a creek followed swinging by thirty-foot vine above it. A professional problem-solver, he is a painting contractor, like his grandfather. Since conversion to Madisonism he has served on the board of James Reeb Unitarian Universalist Congregation, practicing stewardship there and at Holy Wisdom Monastery in Middleton. He has enjoyed working at the polls the last twenty-seven elections.
