Family Court Judge Ronald Richter Tapped to Be New ACS Chief

Mayor Michael Bloomberg selected family court judge Ronald Richter to be the next commissioner of the Administration for Children's services.

Richter, a former Deputy Commissioner at ACS and legal aid attorney, replaces replaces outgoing child services chief John Mattingly, who resigned Tuesday after a rocky seven-year tenure

Mattingly will return to the Annie E. Casey Foundation in Baltimore, Maryland, and spend more time with his family, he said in a statement.

"I reached this difficult decision after much careful thought, taking into consideration my desire to continue contributing to the important work of child welfare, while also wanting to return to Baltimore to spend more time with my family," Mattingly said.

Mattingly was appointed in 2004 after working as the Director of Human Service Reform at the Annie E. Casey Foundation for 12 years and serving on a child welfare board in Toledo, Ohio, according to the ACS's website.

During his tenure, the beating death of 7-year-old Nixzmary Brown in 2006 exposed several flaws within the agency.

And last year, the death of 4-year-old Marchella Brett-Pierce exposed "systemic failures" at the agency, the Brooklyn District Attorney said.

City Councilman Oliver Koppell has been calling for Mattingly to resign. He said the agency needs new leadership.

"I don’t believe he led the agency satisfactorily and there were too many instances of failure to follow up on cases of possible abuse, too many too be excused," said Koppell..
