His last day will be December 31st of this year.
Erickson was a teacher in the Redmond school district for more than thirty years and retired in 2004.
He currently teaches at Central Oregon Community College and has been on the school board since 2006.
Erickson says he feels he would be more useful working to support the district as it moves forward.
The school district will take applications for Erickson's seat. They will appoint a replacement until elections next May.
