Tackmann arrived to Hamline after four seasons at Carthage College, an NCAA Division III member of the College Conference of Illinois and Wisconsin (CCIW). The Arlington, Minnesota native was the graduate assistant men's track & field coach his first two seasons at Carthage, before he was elevated to full-time assistant men's & women's track & field coach for the 2019-20 and 2020-21 campaigns. Tackmann coached the Carthage sprinters, jumpers, and hurdlers.

The Carthage track & field program accumulated three school records, 56 All-CCIW performers, and three CCIW Champions during his time as the graduate assistant. He also assisted in coaching two national qualifying performances with the men's 4x400 meter relay team, which earned All-American honors during the 2019 indoor season. The 2020 campaign saw Tackmann coach one USTFCCCA All-Midwest Region performer, and an NCAA Division III Indoor Track & Field Championship qualifier before the COVID-19 Pandemic canceled the remainder of that season.

Prior to Carthage, Tackmann spent one season at NAIA Morningside College, where he was the assistant track & field and cross country coach. He oversaw the Morningside sprinters, jumpers and hurdlers, as well as the strength & conditioning program. Tackmann coached two school records, 32 All-GPAC performances, and four GPAC Champions. He also molded seven national qualifying performances with the Morningside women's distance medley relay team, which earned All-American honors during the 2017 indoor season.

Tackmann arrived to Morningside after three seasons as assistant track & field coach at his alma mater, Luther College. He coached the Norse sprinters, jumpers and hurdlers. During his time at Luther, he assisted in coaching six school records, 29 All-IIAC performances, nine IIAC Championships, and three IIAC Women's Field Event MVPs.
