The 2010 season marks Dan Witmer's 28th year at the helm of the Oswego State men's lacrosse program. He owns the distinction of being the longest-tenured coach at one school over any collegiate coach in New York. During his career, the Lakers have made six trips to the ECAC tournament (winning the championship once and finishing second twice), won three Empire Lacrosse League titles, and have been ranked among the nation's top 20 teams in both 1994 and 1996. Witmer has sent eight players to the prestigious North/South Game and worked with five USILA All-Americans and one USILA Academic All-American.

As a part-time head coach and a 1996 inductee into U.S. Lacrosse's 100-win Century Club, Witmer enjoys the competitive rivalry of NCAA coaching, but keeps busy with his full-time position teaching high school English. The frequently hectic and demanding pace is balanced by commitment, enjoyment, and support from family, friends, and administration.

Witmer, the 1990 and 1995 Empire Lacrosse League Coach of the Year, is a two-time graduate of Oswego State, earning his BA in Secondary Education in 1982 and his MS in Education in 1987. In recent years, he has returned to the classroom to take additional graduate courses. Besides teaching 11th grade English at nearby Hannibal High School, he also teaches college English, in which students earn six credits through an articulation agreement with Cayuga Community College, and a children's literature elective. Witmer serves as chair of the Hannibal Faculty Association's Scholarship Committee, liaison between Oswego State's field placement office and Hannibal's student teachers, and a charter member of the school's Professional Development School committee. He also coached the Warriors junior varsity girls soccer team for eight years.

An experienced and active guest speaker and clinician, Witmer has worked at various lacrosse camps each summer. He has served on the Alumni Association's "REUNION" planning committee and has made presentations at alumni and educational forums at SUNY Oswego. He recently served a five-year term on the USILA Division III All-American Committee and has also served on the NCAA Championship Advisory Committee. In 2002 he was a co-coach for the USILA's annual North/South Game, leading his team to a dramatic 16-15 victory at Johns Hopkins University. Witmer also serves on the executive board of the Oswego Lacrosse Club.

Originally hailing from Lynbrook on Long Island, the Laker head coach resides in Minetto with his wife, Sue, and their sons, Brian and Eric. He has participated in the Oswego County Runs for Fun series for the past 10 years, running in races ranging from 5 kilometers to 15 kilometers in distance. In 2000 and 2001, he completed two marathons, including the San Diego Rock and Roll Marathon as a Leukemia and Lymphoma Society "Team in Training" member. Other interests include family travel, reading, coaching youth lacrosse, and playing men's league ice hockey.
