Richard Negrin, Philadelphia's managing director and deputy mayor for administration and coordination, is leaving the administration for a job with a city law firm, Mayor Nutter announced Wednesday.

Negrin assumed his posts in July 2010. He oversees Philly 311, the city's nonemergency phone system, and PhillyRising, a program aiming to bolster the quality of life in city neighborhoods.

He will become a partner at Obermayer Rebmann Maxwell & Hippel, focusing on regulatory issues affecting businesses, government, and nonprofit agencies.

"Rich Negrin has been an outstanding public servant and leader in the administration," Nutter said in a release. "He has helped this administration find innovative solutions to long-standing problems and Philadelphians have garnered tremendous value through his work." - Inquirer staff
