Prior to the NFL

Dennison was born in Kalispell, Montana on June 22, 1958. His father George was the 16th President of The University of Montana from 1990 to 2010. The younger Dennison starred in football, baseball and basketball at Rocky Mountain High School where he graduated in 1976.

He attended Colorado State University where he was a football letterman for the Rams in 1976, 1978 and 1979. Wearing uniform number 83 and primarily a tight end for head coach Sark Arslanian, Dennison also saw some action as a wide receiver. He was both a second-team Academic All-American and the recipient of the Merrill-Gheen Award as the university's most outstanding male scholar-athlete in his senior year. He earned a bachelor's and master's degree, both in civil engineering, in 1980 and 1982 respectively.

National Football League

He was last the offensive coordinator of the NFL's Houston Texans from 2010 to 2013. He served in the same capacity with the Denver Broncos between 2006 and 2008, after coaching the team's offensive line from 2001 to 2005, special teams from 1997 to 2000 and working as an offensive assistant from 1995 to 1996. He played eight years as a Broncos linebacker (1982-90). He played college football at Colorado State University, where he played tight end, moving to linebacker when he entered the NFL. During a year off in 1993 for personal reasons, "Rico" assisted Suffield Academy in a successful New England football championship, then returned to Denver to resume coaching for the Broncos. Dennison's move to Houston reunited him with Texans head coach Gary Kubiak, who was a teammate of his in Denver between 1983 and 1990 and a fellow Broncos assistant coach between 1995 and 2005, and who he succeeded as Broncos offensive coordinator in 2006. On January 6, 2013, the Chicago Bears announced that they would interview Dennison for their head coaching position. Both he and Kubiak were appointed quarterbacks coach and offensive coordinator respectively of the Baltimore Ravens on January 27, 2014. Dennison returned to the position of offensive coordinator with the Denver Broncos following the hiring of Kubiak as head coach in January 2015.
