text_A: Duane Parde served as the executive director from December 1996 to January 2006. Lori Roman, who served in the same role from 2006 to 2008, had an imperious style that led to financial difficulties and the departure of two thirds of ALEC's staff. According to Dolores Mertz, then a Democratic Iowa state representative and chairwoman of the ALEC board, ALEC became increasingly partisan during that period, with Roman once telling Mertz "she didn't like Democrats and she refused to work with them." Ron Scheberle became executive director in 2010 after acting as a lobbyist for Verizon Communications (previously GTE) and as an ALEC board member.
