New York�s longest serving police commissioner is going into public speaking after he leaves the department at the end of the year.

Police Commissioner Raymond Kelly said in a statement released by the Greater Talent Network on Monday that he was looking forward to the new opportunity.

�I�m looking forward to sharing the lessons I�ve learned leading the finest police force in the world as we met countless challenges every day,� he said in the statement.

The Greater Talent Network�s speakers bureau is home to authors Sebastian Junger and Nicholas Sparks, as well as former NATO commander Gen. Wesley Clark and former National Security Adviser Tom Donilon. Kelly�s speaker�s fee was not disclosed.

�As a speaker, Commissioner Kelly�s wisdom will inspire and inform, and provide vital lessons toward understanding the role of leadership in a complex world,� said talent network head Don Epstein.

Kelly was police commissioner from 1992-1994, and has held the post since 2002 under Mayor Michael Bloomberg. Under his watch, crime has dropped to record lows, and the city avoided a terror attack. But minorities say they felt targeted by the department�s stop-and-frisk policy.

William Bratton takes over the NYPD Jan. 1. He was chosen by mayor-elect Bill de Blasio.
