Michael DiBerardinis
Deputy Mayor for Environmental and Community Resources
As Deputy Mayor for Environmental and Community Resources, Michael DiBerardinis provides leadership for over 10,000 acres of land, 150 recreation centers and playgrounds, 150 neighborhood and regional parks, 54 library branches and thousands of programs and events throughout Philadelphia.

Susan Slawson
First Deputy Commissioner of Recreation & Programs
Susan Slawson is the First Deputy Commissioner for Recreation & Programs. In this capacity, Slawson has led Philadelphia Parks & Recreation in several transformative initiatives. Her responsibilities have included converting the 5,800 person capacity Dell Music Center into a premiere music venue; leading the Mayor’s Splash & Summer FUNd Campaign, which raised more than $1 million to help keep 69 pools open following significant budget cuts in 2009; and increasing safety at recreation facilities through strategic partnerships with the Philadelphia Police Department (PPD).

Prior to the departmental merger, Slawson was appointed Commissioner of the Philadelphia Department of Recreation by Mayor Nutter in June 2008. Her previous leadership with the Philadelphia Police Department as Commanding Officer of the Police Athletic League (PAL) unit from 2002-2008 prepared Slawson well for this role. PAL serves 26,000 at-risk boys and girls ages 6-18 at 26 youth centers throughout Philadelphia.

Slawson began her civil service career as a Philadelphia Police officer in the 1st District before becoming Commanding Officer of the PPD Public Affairs Unit, representing the Police Department following the terrorist attacks of September 11, 2001.
