Warne was hired as an assistant coach in July 2010 after spending the previous three seasons as an assistant coach at Harvard where his primary responsibility was overseeing the Crimson defense.
During his first season with the Maryland program Warne helped lead the Terps to a berth in the NCAA championship game and the 2011 ACC championship.
Under Warne's leadership, three Maryland players earned All-America honors in 2011, including defender Brett Schmidt, who was also honored as the ACC Scholar-Athlete of the Year.
In his first season with the Crimson program in 2008, the team had the most All-Ivy League selections since 1999 and was ranked in both major polls during the year.
During the 2009 campaign, Warne's defensive unit ranked third in the nation in goals allowed per game and Harvard won eight games for the first time since 2002. The Crimson earned five All-Ivy picks and was ranked as high as No. 11 in the nation in the USILA poll. Harvard allowed 10 or more goals only twice and upset No. 5 Duke to open the season.
In 2010, Warne helped the Crimson win at least six games for the third straight season, as Harvard earned its first victory over No. 6 Princeton since 1990.
Warne came to Harvard from UMBC, where he served as associate head coach for the Retrievers and helped UMBC advance to the NCAA quarterfinals in 2007. He also served as UMBC's main recruiting coordinator, as well as the program's liaison to the equipment and strength & conditioning departments.
Prior to his position at UMBC, Warne served as an assistant coach from 2001-04 at the University of Delaware, working primarily with the offense.
A 2000 graduate of Hofstra, Warne majored in psychology while playing for the Pride from 1995-99. He was a four-year letterwinner and a two-time All-America East honoree. In a senior, he was also named a honorable mention All-American after guiding Hofstra to its third league championship and postseason berth.
While finishing his degree at Hofstra, Warne served as an assistant coach at Plainview-Old Bethpage High School on Long Island. He got his start at the collegiate coaching level in 2000 at the U.S. Merchant Marine Academy before moving on to Delaware.
Warne married the former Jennifer Merrill, who was a four-time letterwinner and team captain at Hofstra in volleyball, in August 2009. The couple currently resides in Baltimore.
