Keister has held a number of executive positions with the company.
John Keister, a founder of Marchex, resigned his board position today.
Keister was executive vice chairman since May 2010 and was a member of Marchex’ board of directors since its inception in January 2003.
He also served in a number of executive positions for the company, including as president from December 2003 through April 2010 and as chief operating officer from January 2003 until March 2009.
Keister was a co-founder of Go2Net, which later merged with InfoSpace.
