Seroka arrived at TSU after a stint at Missouri Southern and 17 years at the University of North Texas, where he spent 16 years as the Head Strength and Conditioning Coach. 

At UNT, Seroka oversaw the Olympic sports while working directly with men’s basketball, women’s basketball and volleyball. 

The strength and conditioning program emphasized the use of proper technique in its core lifts to assist in improving the athleticism and explosiveness of its athletes while implementing flexibility and prehab protocols to prevent injury and shorten the duration of rehabilitation.

Seroka implemented the strength and conditioning program for the men's basketball team which averaged over 20 wins per season from 2006-07 through the 2011-12 seasons, including the 2007 and 2010 Sun Belt Conference Tournament Championships and two NCAA Tournament appearances. Each of those seasons established new school records for wins in a season, 23 (2006-07) and 24 (2009-10).

Seroka helped the North Texas football program establish dominance in the Sun Belt Conference, winning four-straight conference championships and making appearances in four consecutive bowl games from 2001-2004.

Prior to his tenure at North Texas, Seroka held the position of head strength and conditioning coach at Louisiana State University. A 1988 graduate of the University of Southern Mississippi, he was a three-year letter winner in football while also earning two letters in baseball. He was a member of the South squad in the 1989 Senior Bowl.
