Lars Keil joined the Duke women's lacrosse coaching staff in July, 2016 as an assistant coach.
During the Blue Devils' 2017 campaign, Keil saw veteran defender Maura Schwitter garner All-South Region and All-ACC accolades while ranking among the conference's leaders in caused turnovers and draw controls. Keil also oversaw Duke's goalkeeping unit, which included freshman Gabbe Cadoux, who earned the first ACC Defensive Player of the Week honors of her career in April following an 11-save performance at Boston College.
A defensive specialist with extensive coaching experience, Keil came to Durham from Providence, R.I., where he was an assistant for the Brown men’s lacrosse program during a historic 2016 campaign. His season with the Bears saw the squad post a program-record 16 victories and make its first appearance in the national semifinals since 1994. The NCAA semifinal appearance was just the second in program history.
Prior to joining the staff at Brown, Keil served as a men’s assistant coach at Div. III Endicott College in 2013-15 and 2009-11. During that time he guided the Gulls to three league titles and four NCAA Tournament berths while overseeing 13 All-America selections. His teams averaged over 15 goals per game in each of the last two seasons. Keil also assisted in strategic planning for the Endicott program as well as fundraising, budgeting, scheduling, scouting and community service duties.
Keil also spent one season as the head men’s lacrosse coach at Div. II Pfeiffer University in 2013, directing the squad to a 13-4 record – the best in program history – as well as a top 12 national ranking. The Falcons were second in the regular season and Conference Carolinas postseason tournament with three players receiving All-America recognition.
Keil’s coaching career also includes one season spent as a men’s assistant coach at Div. III Bates College in 2012.
Keil played lacrosse collegiately at Springfield College, helping guide the team to three league crowns and three NCAA Tournament appearances. During his time at Springfield, the program advanced as far as the NCAA quarterfinals and captured an ECAC Tournament title.
Keil graduated from Springfield in 2005 with a bachelor’s degree in general education, including a focus in physical education, before going on to earn a master’s in athletic administration from Endicott in 2013.
