Glen Colby, Round Rock ISD trustee and board secretary, submitted his resignation April 5. He cited the time demands of board service as his reason for stepping down.

Colby's resignation will be effective April 13, according to his resignation letter to the board. Colby has served on the board of trustees since 2008 and said that the timing of his resignation will allow the board to appoint a new trustee during the search for the new superintendent. Superintendent Jess Chvez announced Jan. 30 that he will retire in December.

"As I sat in the board meeting this past week and saw not hours, but entire days that are going to have to be carved out to perform the superintendent search, it occurred to me that I am unable to support such a burden from a work and personal life perspective," Colby said in his resignation letter. "I'm truly torn between my sworn obligation to this district and my much older obligation as a father to my children."

Board President Catherine Hanna said the trustees will discuss the process for replacing Colby at their meeting April 9 at 6:30 p.m.

Chvez said he is grateful for Colby's support to the district.

"His decisions were always made in the best interests of children and those of us who work for them," Chvez said. "My experience as superintendent was enriched by Glen's presence on the board."
