Diane Haddeland enters her second season as Jaspers' head women's lacrosse coach. Prior to her time in Riverdale, Haddeland spent three years as an assistant coach at Division III power Fairleigh Dickinson in Madison, NJ. A native of Mahopac, NY, Haddeland brings experience in developing programs to compete on a national level.

During her first season with Manhattan, Haddeland saw a veteran core mesh with a talented group of fresh faces to put on an exciting season. Her first victory as a college head coach came in the home opener in a 13-12 win over Bucknell (2/25) after freshman goalkeeper Christina Fiorinelli stopped a last second shot for the Bison. The Jaspers also captured two impressive comebacks in her debut season, overcoming a five goal deficit against Marist (4/4) and a six goal second half deficit against Niagara (4/14) at Gaelic Park.

In her third season at Fairleigh Dickinson she was the top assistant to Adrienne Booth Carr. In her role, she helped with recruiting and worked with the goalies on the team. She was part of a staff, under Booth Carr, that helped take the Devils from a 1-13 record to a 13-7 overall mark in 2011 and the ECAC Mid Atlantic finals. In 2010, she helped guide Fairleigh Dickinson to an ECAC Mid Atlantic Championship as well as being ranked as the second most improved Division III team in the nation by LaxPower.

Prior to her time in Madison, she played four years (2005-08) of Division III Women's Lacrosse at The College of New Jersey for Coach Sharon Pfluger. Her college resume includes three final four appearances and two National Championships in 2005 & 2006. She graduated in 2008 with a Bachelor of Science in Health and Exercise Science before going on to achieve a Masters of Sports Administration from Fairleigh Dickinson in 2011.

The ability to mold a program did not begin in college either. Haddeland attended Mahopac High School where she helped to start the Girls Lacrosse program and served as team captain her senior season. A passionate member of the lacrosse community, Haddeland has spent the last three years working as a coach or director at multiple lacrosse schools and academies including The Lacrosse Academy at Fairleigh Dickinson, Morris Storm Lacrosse and working as a volunteer coach for the Mahopac lacrosse clinic since 2000.
