Early life and playing career
Costello is from Royalton, Minnesota.[3] He played college football as an offensive lineman for Bemidji State University from 1995 until a career-ending injury in 1998.[1] Following the injury, he moved into coaching as a student assistant on the Beavers’ staff, working with the offensive line.[1]
Coaching career
College coaching
After his initial work as a student assistant at Bemidji State, Costello spent one season (2000) as the offensive line coach at Wisconsin–Oshkosh. He then returned to Bemidji State to complete his graduate work, serving as the Beavers’ running backs coach and strength coordinator.[1]
Costello later held a series of roles at small-college programs:
- Offensive line coach, run game coordinator and strength and conditioning coordinator at Dana College[1]
- Offensive coordinator at Culver–Stockton College (2005–2006)[1]
- Offensive line coach, strength coach and equipment manager at Truman State University for three seasons prior to joining Valley City State[1]
Valley City State
Costello joined Valley City State University in 2010. In his first season, he served as co-offensive coordinator and quarterbacks coach. From 2011 to 2013 he was promoted to offensive coordinator and offensive line coach, while also working as the program’s strength coach, academic coordinator and camp coordinator.[1]
Wisconsin–Stevens Point
In 2014, Costello joined the University of Wisconsin–Stevens Point as run game coordinator and offensive line coach; he also served as recruiting coordinator.[1]
Winnipeg Blue Bombers
Costello joined the Winnipeg Blue Bombers in 2016 as assistant offensive line coach under veteran offensive line coach Bob Wylie.[2] He was promoted to offensive line coach in 2017 and has held the role since then.[2]
With Costello overseeing the offensive line, Winnipeg has been widely regarded as one of the most dominant and consistent units in the CFL:
- The Blue Bombers have produced multiple CFL All-Stars along the offensive line, including future Hall of Famer Stanley Bryant, who has won multiple Most Outstanding Offensive Lineman honors.[2]
- Winnipeg’s line has paved the way for league-leading rushing attacks – first with running back Andrew Harris, who captured three consecutive CFL rushing titles, and later with Brady Oliveira, who produced three straight 1,000-yard seasons and back-to-back CFL rushing crowns while also being named the league’s Most Outstanding Canadian and, in 2024, the CFL’s Most Outstanding Player.[2]
- The Blue Bombers have consistently ranked among the league’s best in sacks allowed and offensive production, leading the CFL in scoring in multiple seasons while protecting quarterbacks such as Zach Collaros.[2]
Costello enters his 10th season on the Blue Bombers staff in 2025 and his eighth as the club’s offensive line coach.[2]
Personal life
Costello is a native of Royalton, Minnesota, and is an alumnus of Bemidji State University.[3]
