He has previously served as an assistant coach for the Utah Jazz of the National Basketball Association and Dartmouth Big Green men's basketball of NCAA Division I as well as the head coach at West Virginia Wesleyan College and Le Moyne College of NCAA Division II.

He played for his father John Beilein at West Virginia University where he tallied a total of 1001 career points.

[2] He was born on March 23, 1983, which he says was the day before his father began a nine-year stint at Le Moyne as head coach.

[3] He was part of West Virginia teams that reached the elite eight and sweet sixteen rounds of the 2005 and 2006 NCAA Division I men's basketball tournament.

[6] A roommate of Mike Gansey, Beilein was the sixth man for the 2006 team and for a time (as he vied with Kevin Pittsnogle) held the school record for career three point shots made.

[4] He graduated from West Virginia University with 242 three-point field goals made and a Bachelor of Science in athletic coaching education.

[3] At Le Moyne, his first game was a 2015 exhibition matchup against his father's Michigan Wolverines at Crisler Center that was attended by 70 relatives.

[12] That season, he led Le Moyne to the number 1 seed and the host in the NCAA Division II East Regional.

[25][26] However, on October 24, 2019, just weeks before the beginning of the season, Beilein resigned for "personal reasons", with assistant coach and former Duke standout Greg Paulus named as his replacement on an interim basis.
