Adam Thiel Resigns as Philadelphia Managing Director

Mayor Cherelle L. Parker has appointed Carlton Williams to oversee the managing director’s 36-department portfolio, a move that puts operational control of core city services under new leadership as the administration approaches next year’s mayoral primary.

Overview

  • The mayor announced Tuesday that Adam Thiel is leaving city government and Carlton Williams, who runs the Office of Clean and Green, will succeed him as managing director.
  • Parker said the managing director role supervises 36 departments and 558 positions, giving Williams direct authority over emergency management, streets, parks, fire, water, shelters and other day-to-day services.
  • Thiel served as managing director since January 2024 after eight years as fire commissioner and led projects like the Riverview Wellness Village, but reporting shows he took extended leave last year for military and other paid leave and reported significant outside consulting income.
  • Williams is being promoted based on his Clean and Green record, which Parker cited as cleaning roughly 191,469 city blocks and expanding neighborhood cleaning and trash-collection programs.
  • The announcement did not set a formal transition date or outline Williams’s immediate policy agenda, leaving open questions about operational continuity and how the change will affect ongoing initiatives in Kensington and citywide shelter and recovery services.
