Bucks General Manager John Hammond announced that Jim Boylan, Lionel Hollins, Kelvin Sampson and Joe Wolf will join Scott Skiles' coaching staff as assistants.
Boylan joins the Bucks after four seasons with head coach Scott Skiles on the Chicago Bulls staff, including serving as the interim Head Coach for the final 56 games during the 2007-08 season when Skiles was fired.
Lionel Hollins' last two coaching stints came as assistants in Memphis with the Grizzlies and in Phoenix with the Suns.
Kelvin Sampson comes to the Bucks after two seasons as head coach at Indiana University. He resigned after the NCAA charged Sampson and the Hoosiers with five major NCAA infractions.
Joe Wolf is a native of Kohler, Wisconsin. He joins the Bucks after serving as the Head Coach and General Manager of the NBA Development League's Colorado 14ers.
The Bucks staff will also include Bill Peterson, assistant coach/player development, who joined the Bucks prior to the 2007-08 season.
