After internships at the City of Bellingham and the Town of Hunts Point, Jon was hired as a deputy prosecuting attorney for San Juan County in 2006. Initially, Jon focused on helping the County achieve compliance with the Growth Management Act while also handling land use cases and leading child support enforcement for the office.
