When incumbent Mary Taylor ran for Ohio Auditor, Dyer sought to replace her.
Facing another political newcomer in Republican Christina Croce, Dyer won, taking the Forty Third District.
In his second term, Dyer was named Chairman of the House Finance Committee's Subcommittee on Primary and Secondary Education.
With 2010, Dyer ran for a third term, and Todd McKenney, a councilman from New Franklin, Ohio, was his Republican opponent.
Dyer filed petitions with the Summit County Board of Elections on February 2, 2011 to run for a judgeship in the Barberton Municipal Court District.
