In preparation for celebrating 1989's Bicentennial 200th anniversary founding of the U.S. Marshals, efforts began in February 1988 by Dr. Richard Collins, a Scottsdale orthopedic surgeon, organizing a group of local horsemen and women to promote the USMS and help celebrate the U.S. Marshals. The group selected eye-catching uniforms with matching tack and on April 19, 1988 they became the second organized U.S. Marshals Posse in the United States.
The founding members include Dr. Richard Collins, Dr. J. Michael Foley, Dr. Gary Gradke, Dr. G Glen Hait, Marston Holben, Forrest Holden, Kenny Mott, Wendell Petefish, Dr. Scott Petersen, Elizabeth Petersen, Stephen Schumak, Malcom Strohson, and Dr. Merlin Webb.
