Justin Heinzen is in his fifth season as the head women's basketball coach at Loras College. In four seasons at the helm of the Duhawks, Heinzen has compiled an overall coaching record of 61-46, which includes four straight appearances in the Iowa Intercollegiate Athletic Conference Tournament.

Playing the 13th strongest schedule in NCAA Division III a season ago, Heinzen's Duhawks finished 15-12 overall and 10-6 for a fourth-place finish in the IIAC regular season standings. Loras advanced to the semifinals of the conference tournament for the third straight year before being edged by top-seeded Coe College, 54-51. The IIAC champion Kohawks later advanced all the way to the NCAA Tournament Sweet 16.

Along with his team's strong tournament finish, Heinzen's squad maintained a 3.339 cumulative team grade point average and had three players land on the All-IIAC Academic Team. Heinzen, who is third at the school in both wins (61) and winning percentage (.570), has coached eight players to all-conference honors through four seasons.

In Heinzen's first season at Loras, he led the Duhawks to the program's second-best season in terms winning percentage (.680) in 2007-2008. After a program-best 10-0 start, which is also a record for most consecutive wins in a season, Loras wrapped up the 2007 calendar year with a 23-3 record, good for seventh-best in NCAA Division III.

The 2008-2009 season was highlighted by a second place IIAC finish, a semifinal appearance in the conference tournament, a win over NCAA Division II opponent Upper Iowa, and a team grade point average of 3.307. 

Prior to arriving at Loras, Heinzen spent two seasons (2005-2007) serving as an assistant coach at Lakeland College (Wis.) under one of the NCAA Division III's all-time winningest coaches, April Arvan. In two seasons at Lakeland, the Muskies went 34-17 overall, capturing a Lake Michigan Conference regular season and tournament championship while making its fifth appearance in the NCAA Division III Tournament.

He began his coaching career at Manitowoc (Wis.) Lutheran High School and has held coaching positions at University of Wisconsin-Manitowoc, Reedsville (Wis.) School District and Higher Level Camps, one of Wisconsin's premier AAU organizations.

Heinzen graduated from Wisconsin Lutheran College in 2004 with a bachelor's degree in American history with a minor in political science. A 1999 graduate of Manitowoc Lutheran High School, Heinzen lettered in basketball, baseball and cross country for the Lancers.  Today, the Manitowoc, WI native resides in Dubuque with his wife Kristina.
