Alan Harrison is a writer, father, performer, consultant, recovering artist, and the author of the soon-to-be-best-seller “Scene Change.” For 30 years, he has led, produced, directed, promoted, raised money for, starred and failed in over 300 theatrical productions on and Off-Broadway and at prestigious (and not so prestigious) nonprofit arts organizations across the country. He’s also a two-time “Jeopardy!” champion so, you know, there’s that. The arts invoke passion (mostly from artists), but nonprofit arts are only successful when they result in measurably positive change among those that need it most. When a nonprofit’s donors are also its recipients, then its mission devolves into meaningless puffery, flapdoodle, and codswallop.
