In 2024, Ed Bond will be joining the CPO Board. A decade earlier, as he contemplated retirement and pondered his post-thirty-year career with Kimberly-Clark Corporation, a close friend extended an invitation to attend a Sunday service at Concord’s West Union Church. During the sermon, he was enlightened about the historical efforts of the Town of Concord and the ongoing initiatives of Concord Prison Outreach (CPO) to support the incarcerated population of MCI Concord.
Following the service, Ed engaged in a discussion with a group of dedicated CPO volunteers, which solidified his conviction to contribute meaningfully. His initial volunteer endeavor involved developing and delivering 75 two-hour workshops on Basic Reading and Writing Skills at MCI Shirley. Subsequently, he underwent training in the ‘Another Way to Go’ program and actively participated in its implementation at MCI Concord’s Brave Unit. Ed also took part in a recent two-day Restorative Justice (RJ) Retreat at MCI Norfolk and is currently in the process of completing an eight-week Restorative Justice facilitation training program. He eagerly anticipates advancing the Restorative Justice Program in the coming weeks.
Residing in Lexington, MA, Ed looks forward to leveraging his life experiences and skills to serve the community through his role on the CPO Board.
