Prior to his Oberlin tenure, Polak served as the lead assistant coach at Kenyon College for three seasons where he was the Lords' offensive - and recruiting coordinator. Polak was instrumental in making the Lords a perennial force within the North Coast Athletic Conference with two conference tournament appearances (2018-19) and a 5-1 start in 2020 before the season was cut short due to COVID-19.

In 2019, Polak's high-powered offense ranked third in the NCAC in goals per game with 14.29 as they posted 243 tallies and 131 assists, 57 which came out of the stick of Nick Vitale to rank second in the league. When last season came to an abrupt halt, Kenyon's Will Robbin's was fifth in the conference in points with 18 (13 g, 5 a).

Polak mentored nine All-NCAC selections during his time with the Lords and helped the team acheive a record of 25-13 overall and 11-5 in the NCAC.

Prior to coming to Gambier, he was the director for True Lacrosse Idaho and also worked as the head lacrosse coach at Bishop Kelly High School in Boise, Idaho.

Polak got his start in coaching as a college counseling Intern and assistant lacrosse coach at Western Reserve Academy in Hudson, Ohio in 2015 and 2016.

A 2014 graduate of Washington College (MD), Polak helped the Shoreman make three NCAA Tournament appearances as a midfielder and attackman. As a senior, he guided WC to a Centennial Conference Championship in 2014 and an appearance in NCAA DIII semifinals.

Polak earned a bachelor's degree in business management from WC and completed a Master's of Science in Sport Coaching from West Virginia University in December of 2020.
