History
Tiber Creek Group was founded as Griffin, Johnson & Associates in 1987 by Pat Griffin, former aide to West Virginia Democratic Senator Robert Byrd, and David Johnson, former aide to Maine Democratic Senators Edmund Muskie and George J. Mitchell.[3] The additions of Republicans Peter Madigan, Michael Boland, and Janet Mullins Grissom in the early 2000s added bipartisan capabilities to Griffin, Johnson & Associates.[4] At the same time, the firm also brought in Democratic operatives Harold M. Ickes and Janice Enright. Changes to the firm’s senior leadership, such as the addition of Jonathon Jones, caused Griffin, Johnson & Associates to change names multiple times. In 2021, Griffin, Johnson & Associates, then known as Peck Madigan Jones, re-branded to Tiber Creek Group. Tiber Creek also owns the Ickes and Enright Group, which was co-founded by former Clinton White House Deputy Chief of Staff Harold Ickes in 1997 [5] Jonathon Jones serves as managing partner of Tiber Creek Group.[6]
