Calhoun served as West Virginia's director of operations for the men's basketball program from 2008-11, but he was elevated to a full assistant coach by Mountaineer head coach Bob Huggins last summer.
After one year as an assistant coach at WVU, sources said Calhoun has accepted the opportunity to be the head coach of his own program, as he takes over the Division II Fighting Falcons.
Calhoun came to West Virginia in 2007 from Walsh University in North Canton, Ohio, where he spent three seasons as assistant basketball coach. Walsh posted an 82-21 record during his three seasons there, including the 2005 NAIA national championship, 2006 NAIA Elite Eight and 2007 NAIA Sweet 16.
The Cleveland, Ohio, native began his coaching career at Cincinnati in 2003-04, where he served as a student assistant under Bob Huggins. That year, the Bearcats were 25-7 overall and advanced to the second round of the 2004 NCAA tournament.
Calhoun played two years of college basketball at Cleveland State for Rollie Massimino. While at CSU, he was a member of the Dean's List as well as the Student-Athlete Advisory Board.
Calhoun graduated in 2004 from Cincinnati with a bachelor's degree in criminal justice and a minor in communications. He has a son, Jordan, and married the former Sarah McKenna in May 2011.
