Debbie Sansome Garber


CRC Board Member, Mediator, Court Coordinator

Debbie has been a certified mediator with CRC since 2010. Guiding people to find their own mutually agreed upon solution to a dispute through communication and discovering common ground, is just one of many aspects of mediation Debbie enjoys. She finds that every mediation presents a new and different challenge and a glimpse of humanity at it finest and often its most vulnerable. She applies the tools, skills, and techniques learned through mediation, in a variety of areas in her life.

Leaving a twenty year career in upper management of a large non-profit community service organization, Debbie moved from Palo Alto to Grass Valley in 1997 to raise her two children in a more rural environment. She soon began a new career as a Special Education Resource Specialist, retiring in June 2020. In addition to mediating in court each week, Debbie looks forward to spending her retirement time in her garden, spending time with friends, traveling, taking long walks with her dog, and finding some peace and joy in each day.
