At Tuesday night's Jefferson Union High School District Board meeting, Trustee Laurie Frater announced he was resigning immediately.
"It's with mixed feelings I did it, too," he said today.
Frater cites health reasons for his resignation, saying that he got sick six weeks ago and had to cancel many engagements.
"It prompted conversation about my kidneys," he said.
Frater also said he's seeking full-time employment and his time commitment to the board may hinder the job search.
"There were a lot of personal issues, and I thought it was a right thing," he said.
Frater's term as a board trustee ends in November. He said he had already decided not to run again before opting for a resignation.
District Superintendent Tom Minshew said that at the next meeting, the board will need to decide if it wishes to appoint a replacement for Frater or leave his seat open until November's election.
Frater told Pacifica Patch he would email his reisgnation letter for posting later today.
