Moss Bresnahan, president of KCTS Television in Seattle, resigned Thursday.
"My reasons for making this very difficult decision are deeply personal -- to attend to family-related issues that have arisen," Bresnahan said in a note to public television managers.
"I'm so proud of our many accomplishments to date, and I know that KCTS is poised for even greater things in the coming year," he told the execs.
Prior to his arrival in Seattle in November 2008, Bresnahan served as president of South Carolina ETV and WVPT in Harrisonburg, Va. He also spent six years as a board member of the International Public Television Screening Conference (INPUT) .
The KCTS Board announced that Rob Dunlop, e.v.p. of operations at Fisher Communications in Seattle, will lead the station on an interim basis. Dunlop has been with Fisher more than two decades, holding a range of positions in radio, television and digital initiatives.
