Katy Dissinger was promoted to head coach of the Trinity College women's lacrosse team in June of 2014. Dissinger, the 2012 Intercollegiate Women's Lacrosse Coaches Association (IWLCA) National Assistant Coach of the Year and the 2016 IWLCA Division III Berkshire Region Coach of the Year, has played a significant role in Trinity's unprecedented run to six-straight NCAA Division III Championship Final Fours from 2012-2017 including an NCAA Championship season in 2012. She was also a participant in the 2011 NCAA Final Four as a captain for Bowdoin College's squad. Trinity also played in the NESCAC Finals for the seventh year in a row in 2017, and won the league title for the fifth-straight year in Dissinger's rookie year as head coach in 2015.
In 2017, Dissinger led Trinity back to the NCAA Final Four, as the Bantams posted a 17-5 overall record and 8-2 NESCAC mark. Trinity fell to eventual National Champion Gettysburg, 8-4, in the semifinals, snapping Trinoity's streak of five NCAA Finals appearances in a row. Senior Clare Lyne capped off her career by being named as the IWLCA National Division III Attacker of the Year, as Dissinger guided a Bantam team that featured three All-Americans, six Intercollegiate Women's Lacrosse Coaches Association (IWLCA) All-Region players and 13 NESCAC All-Academic selections.
In her second season at the helm of the program, Dissinger guided the Bantams to the NCAA Final Four and the National Championship game for the fifth straight season. Trinity finished the season with an impressive 19-4 overall record and a 9-1 mark in NESCAC action. After ending the regular season as the No. 1 seed in the NESCAC Championship Tournament, the Bantams fell to Middlebury, 10-7, in the league title game. Senior midfielder Martha Griffin capped off a stellar season for Trinity, as she was named as the Eastern College Athletic Conference (ECAC) Division III Offensive Player of the Year, the NESCAC Player of the Year for the second straight season, the first Bantam lacrosse player to grace the CoSIDA Academic All-American Team, the Trinity College Senior Female Athlete of the Year (Trinity Club of Hartford Award) in the spring. Dissinger led a 2016 squad that boasted three All-Americans and 11 NESCAC All-Academic honorees.
Dissinger's rookie season as head coach was equally remarkable, as the Bantams finished 21-2, tying the College record for wins in a season, and downed Franklin and Marshall, 11-6, in the NCAA Semifinals before falling to Cortland State, 17-6, in the finals. The Bantams won their fifth consecutive NESCAC Championship title with a 13-8 triumph against Bowdoin on May 3, and won 21 games in a row in between a season-opening loss at Colby and the NCAA Finals. Griffin garnered National Midfielder of the Year honors and three Trinity players received All-American honors.
Dissinger arrived at Trinity as an assistant coach in 2011-12, and immediately proved herself to be a huge asset to the women’s lacrosse program. She performed all the duties of head coach during the fall while the head coach was on a semester-long maternity leave, and guided the team through its off-season preparations following a home loss to Bowdoin in the 2011 NCAA Quarterfinals. The Bantams went on to an historic run to the College's first NCAA crown in any women's sport that spring. The Bantams finished that season and defeated Cortland State and Salisbury in NCAA Final Four to win the title. Trinity won its first 21 games in 2013, before falling to Salisbury in the NCAA Finals, and finished 19-3 in 2014 including an 8-7 win over top-ranked and previously-undefeated Cortland State in the NCAA Semifinals before losing, 9-6, in the finals to Salisbury.
Dissinger earned her bachelor's degree from Bowdoin in visual arts and environmental studies in 2011, and added a master's degree in public policy from Trinity in 2013. Dissinger starred at center midfielder for her alma mater from 2008 to 2011, earning IWLCA All-Regional honors twice and receiving the program's Ellen Tiemer Trophy for excellence in lacrosse by a vote of her teammates and her coach. Dissinger, who was also an assistant field hockey coach at Trinity from 2011 to 2013, is an assistant professor at the College in physical education. Dissinger has organized a fall clinic for inner-city youth in Hartford the last three autumns, and serves on the athletic department's marketing and communication committee and its sports medicine committee. She resides in Hartford.
