In his first four seasons on staff, Clemsen has helped coach Mizzou wrestlers to three NCAA Titles, 18 All-America honors and 23 individual Conference Championships. In 2014-15, Mizzou enjoyed one of the best seasons in school history, where the Tigers claimed a fourth straight conference championship, sent 10 wrestlers to the NCAA Championships and claimed fourth place overall nationally. Clemsen also helped guide senior Drake Houdashelt to an individual national title at 149 pounds. In 2015-16, Mizzou repeated as MAC Champions, sent nine wrestlers to the NCAA Championships and finished sixth nationally with four All-Americans. One Tiger, J’den Cox, claimed an NCAA Title, marking the third straight year a Tiger has reached the top of the podium.
Clemsen helped Mizzou achieve great success again in 2016-17, as Mizzou won its sixth straight conference title and third straight top-10 NCAA finish. J’den Cox reached the top of podium once again, becoming the first-ever three-time national champion in program history, as Mizzou matched a program-best mark with five All-Americans. In 2017-18, Clemsen helped guide Mizzou to a seventh straight conference title and fourth straight NCAA top-10 finish. Seven Tigers won individual conference titles at the MAC Championships, a program best.
Clemsen brought with him a tradition of success as he has coached 38 NCAA qualifiers, six All-Americans and eight ACC Champions at Virginia. He helped the program reach No. 11 in the nation during the 2012-13 season, which stands as a program-best ranking.
With Clemsen's assistance, the Cavaliers defeated then-No. 9 Central Michigan, marking the program's first-ever win over a top-10 opponent. In his first season with the Cavaliers, Clemsen helped lead the team to an ACC Championship, the first for the program since 1977. The team went on to earn a 15th-place finish at the NCAA Championships. It was the Cavs' second consecutive top-25 finish at the NCAA Championships in his second season with the program.
Not only did Clemsen help lead Virginia to success on the mat, but his teams were consistently successful in the classroom as well. The Cavs recorded the fifth-best team GPA in the country during the 2012-13 season, and eight Cavaliers were named to the NWCA All-Academic Team as well. Seven Cavaliers were named to the team the previous season.
Prior to his time at Virginia, Clemsen served as the director of wrestling operations at Oregon State for two seasons.
A 2007 graduate of Edinboro, Clemsen was an All-American wrestler and four-time NCAA qualifier. He finished his career with a 121-35 record, good for ninth in the school's history. Clemsen stands as Edinboro's 14th wrestler to win four Pennsylvania State Athletic Conference Championships, and he was also named an Eastern Wrestling League Champion.
A two-time Academic All-American, Clemsen graduated with the highest GPA of any wrestler in Edinboro history. Clemsen continued his career at the international level as a University Nationals All-American and a University World Team Trials runner-up.
Clemsen was a standout wrestler at Moberly senior high school, winning three Missouri State Championship titles during his high school career. Clemsen and his wife, Lindsay, have two children: a daughter, Payten and a son, Porter.
