Dave Tanzyus will be appointed Madison County administrator at a special board meeting at 5 p.m. Tuesday. A former aide to Republican Congressman Mike Bost, Tanzyus has been serving in Chairman Kurt Prenzler's administration since December when the board confirmed his appointment as community development administrator. With 30 years of government experience, Tanzyus will fill the seat that had been occupied by administrator Doug Hulme, who was terminated by the county board last April. Prenzler also will appoint Chris Bethel as IT director. Bethel started working for IT in January 2017, under former director Rob Dorman, whom the county board also terminated last April. Bethel began as a project manager, then became manager of network services.
