Jim Leddy, Sonoma County's community and government affairs manager, has been hired by Mono County as its top administrative officer.

Leddy, 45, a former candidate for the state Assembly and Santa Rosa schools trustee, has been Sonoma County's chief spokesman and government relations official since 2008. He was recently promoted to deputy county administrator. His 2012 pay was $154,916.

He is set to start work in Mono County on June 10. His annual salary will be $160,000, according to a Mono County announcement. His last day of work for Sonoma County is June 7.

"It's an incredible opportunity to work for another great organization and live in another beautiful part of California," said Leddy, a Monte Rio native.

Mono County, centered in Bridgeport, takes in the Eastern Sierra near Mammoth Lakes and stretches to the Nevada border. It has a total population of 14,200 and a county government yearly budget of $71 million, with 305 full-time positions.

Leddy was executive director of the Napa County Planning and Transportation Agency from 2006 to 2008. He was a Santa Rosa city schools trustee from 2001 to 2008 and ran for the state Assembly in 2004.

From 1993 to 1998 he was a field representative for then-state Sen. Mike Thompson. He served as district director for then-state Sen. Wes Chesbro from 1998 to 2006.
