Aaron Marcelli, of Mason, is a new member of the Warren County Board of Developmental Disabilities. Born and raised in Canton, Ohio, he spent 20 years living in northwest Georgia before returning to Ohio in 2025 with his wife, Katy, and their four children. One of their children receives services through the Warren County Board of Developmental Disabilities, giving Marcelli a personal connection to the organization’s mission.



He brings more than a decade of experience in the developmental disabilities field, having worked as a job coach, business manager, and chief financial officer for a provider organization. Marcelli also operates Marcelli Bookkeeping Services, supporting small businesses with financial services. He hopes to bring a fresh perspective to the board while continuing to support inclusion, informed choice, and opportunity for individuals with disabilities in Warren County.
