Philadelphia Managing Director Brian Abernathy is resigning his post, effective Sept. 4.

Mayor Jim Kenney announced on Tuesday morning Abernathy's departure from city government.

"I’ve worked closely with many public servants throughout my career, and few match Brian’s level of integrity and commitment to making our city better," Kenney said in a prepared statement. 

The mayor particularly thanked Abernathy for his recent work managing simultaneous crises, including the COVID-19 pandemic and the civil unrest in June sparked by the death of George Floyd.
