Norm Colb, who for two decades has served as head of school at Menlo School in Atherton, will retire in June 2013, he announced Tuesday, Dec. 13.
"Both personally and professionally, my years here have been more rewarding than I can possibly say," he said in an email to the parents of students who attend the private, coeducational college prep school, based in Atherton. About 800 students attend middle and high school grades.
Mr. Colb's plans are still taking shape, he said, but retirement will enable him and his wife Susan to spend more time with family -- "on four continents!"
Completing a book on the challenges facing American education and "pursuing a host of interests that have been calling out to me for quite some time" are also on his retirement agenda, he said.
The school has already appointed a search firm and formed a committee to search for a successor, he noted.
Meanwhile, for the next 18 months, he said, " I mean to be as active as ever."
