Dean Koski, entering his 33rd season as head coach of the Lehigh Men's Soccer program in 2025, embodies consistent success and dedication to the sport. Since taking over in 1991, Koski has led the Mountain Hawks to three Patriot League Tournament championships (2000, 2015, 2019), two Patriot League regular season titles (2006, 2019), and five NCAA tournament appearances. His tenure has seen the development of five All-Americans, 23 First Team All-Region selections, and 51 First Team All-Patriot League selections. Five of his players - Andrew Mittendorf, Kevin Jackson, Adam Williamson, Adam Welch, and Mark Forrest, have been drafted by MLS franchises.

Koski’s recent accomplishments include coaching and mentoring, Stevo Bednarsky, All-league and United Soccer Coaches All-Region team and currently playing NYFC in the MLS Next Pro league, Jack Sarkos, a 2022 first-team All-Patriot League honoree and United Soccer Coaches All-Region selection currently playing for Crown legacy in the MLS Next pro league, as well as Euan Forrest, who became Lehigh's first two-time College Sports Communications All-District honoree. In 2021, Koski secured his 250th career victory with a win over Lafayette, closing the season with a career record of 253-222-69—the highest win total in program history.

The 2019 season stands out as a landmark year for Koski’s program. Under his leadership, Lehigh captured both the Patriot League Championship and the regular season title, finishing with a 13-5-3 record, an unbeaten league season, and an undefeated home record at Ulrich Sports Complex. This campaign earned Koski his fourth Patriot League Coach of the Year honor, a league record. Key players such as Josh Luchini, the Patriot League Offensive Player of the Year, and Will Smith, the Patriot League Goalkeeper of the Year, were instrumental to the team's success, with Luchini also named a United Soccer Coaches NCAA Division I Third Team All-American.

Koski's teams have consistently excelled in academics as well, with numerous players earning spots on the Patriot League Academic Honor Roll and receiving NSCAA Academic Awards. His 2011 team was recognized as one of the nation’s top defensive teams, ranking second nationally in save percentage and third in goals-against average. Under Koski's guidance, players such as Kevin Strunk and Ciaran Nugent achieved league and national recognition for their defensive prowess.

An advocate for the broader soccer community, Koski has served as a staff coach for both USSF and NSCAA coaching schools and holds multiple coaching diplomas, including the NSCAA Advanced National Diploma, USSF “A” license and the England FA Preliminary and International Diplomas. He has chaired the Patriot League soccer coaches committee and been a featured clinician for New York/New Jersey MetroStars. Coach Koski has also presented at the United Soccer Coaches Convention to a national audience.

Koski's impact extends beyond Lehigh to both the local and national youth soccer landscapes. A strong presence in the Lehigh Valley community, he is currently the president of Lehigh Valley United Soccer Club, sits on the board of LVU-Rush, and was recently elected to the ECNL Board of Directors representing the North Atlantic Conference. Previously, Koski served as President of the Lehigh Valley Youth Soccer League and as Chair of the Hanover Township Recreation Board. Koski also sits on the ArtsQuest World Cup 2026 Committee and has spent the past 20 years advising and training parent-coaches for the Greater Bethlehem Soccer League. In addition, he founded and serves as president of the Lehigh Soccer Academy, the longest-running soccer camp in the region, which has trained hundreds of young athletes each summer for over 30 years.

Originally from Cherry Hill, New Jersey, Koski played collegiately at West Chester University, where he was an Honorable Mention All-Region and team captain. His playing career at WCU includes an ECC Championship in 1978 and 20 years of amateur soccer in Southern New Jersey and Bethlehem. Koski holds a bachelor’s degree in health and physical education from West Chester University and a master’s degree in special education from Bloomsburg University. He lives in Bethlehem with his wife, Lisa, and their four sons, Alec, Trevor, Spencer, and Blake.

For Koski, coaching is more than a profession; it is a passion for teaching and developing. "Coaching soccer is what I do, but teaching and mentoring aligns more with who I am professionally…I am an educator" he says. "The relationships I’ve forged with my players over the years are especially rewarding, particularly after they graduate when I no longer am seen as only their coach. To be an integral part of their lives for four years and watch them develop from boys to men is privilege." His approach emphasizes the holistic development of his players, recruiting individuals who are not only dedicated athletes but also committed students and individuals of high character. “My intentions are to coach, mentor and teach the human being, not the human doing.”

As he continues to lead Lehigh Men’s Soccer, Koski remains focused on fostering a program that values team first, self-discipline, unity, respect, grit, excellence, and resilience—qualities that have defined his career and contributed to the enduring legacy he’s building at Lehigh University.

The relationships I have been able to forge with my players is especially rewarding. To be a part of their lives and watch them develop from boys to men is a privilege."

We have players that love to play and come here wanting to play."
