ACQUIRED: Signed with Minnesota United on 1.23.2017

Woodbury native Kallman has spent his entire professional career with Minnesota since first joining the club in 2013. With his signing in January 2017, he became the first Minnesotan to join the Loons in MLS. He made 23 appearances (23 starts) during the inaugural season, contributing two goals and captaining the side on a number of occasions.

The central defender has taken on a tremendous amount of leadership and earned high praise from Head Coach Adrian Heath, who described his performances as "excellent" midway through 2017, adding that "there's not many [players]" he would swap out for Kallman in MLS. He was a mainstay in Minnesota's defense in 2016 and 2017, using his speed and strength to take down attackers. His height is a huge asset on both ends of the pitch, clearing lofted balls out of the MNUFC penalty area and nodding crosses into the opponent’s net. Never one to back down, he frequently makes incisive runs through the midfield and deep into enemy territory.

Prior to joining Minnesota, Kallman played four seasons at Creighton University, leading the Bluejays to back-to-back College Cup appearances. He saw limited playing time in his first season with MNUFC, featuring in just one match. But his upside in the professional game was clear and he proved his value as a dual-threat player in 2015, scoring his first professional goal late on in the campaign.

Kallman attended Woodbury High School, where he lettered in soccer, tennis, basketball and football, earning first-team all-state and all-conference in the former as a senior. He was also a member of the Minnesota Olympic Development Program.
