HERCULES -- Recreation Manager Greg Dwyer is leaving after almost 20 years in Hercules to become community services manager in San Pablo.

"I grew up in San Pablo, so I'm returning to my roots," Dwyer said over the phone from his Hercules office Tuesday. "I'm going to miss everybody here. They've got a great group of employees."

Dwyer started with Hercules in September 1993 as a recreation leader and youth basketball coach, eventually working his way up to recreation manager. He rose to senior project manager in the Hercules Redevelopment Agency in 2011 but went back to recreation manager when the state abolished redevelopment agencies effective last year.

He cited the Hercules Teen Center, Frog Pad Park and Duck Pond Park among recent accomplishments that he played a role in.

In San Pablo, Dwyer will replace the current community services manager, Nancy Thome, who has tendered her resignation but will stay on with San Pablo into August, said San Pablo Deputy City Clerk Lehny Corbin. Dwyer's first day on the job in San Pablo will be July 8.

He will report to Walt Schuld, who is San Pablo's assistant city manager for external services as well as chief of police. The Community Services Department administers recreation, including an array of classes, and youth, family and senior services; it also oversees rentals of city facilities.

Wednesday will be Dwyer's last day on the job in Hercules, although technically his last day is Thursday, which is the Fourth of July holiday.
