Since graduating Yale with a B.A. in Philosophy in 2007, DiCo has been teaching in NYC schools. After four years of teaching and coaching debate at Frederick Douglass Academy in Harlem, DiCo moved to Achievement First Brooklyn High School, teaching primarily Latin and Speech & Debate. The AF Debate Team was founded in September 2011 and the AF Speech Team was added in September 2014. In 2016, DiCo was awarded the Teach for America Alumni Award in Excellence. In 2017, DiCo earned distinction as a Stage 5 Master Teacher, the highest distinction that the Achievement First network bestows on its faculty.  DiCo founded the Brooklyn Debate League in 2017.

Trevor Colliton found a family among his teammates at the City University of New York. Trevor established the CUNY Parliamentary Debate Team in 2014, serving as its president for 4 years and continues to coach post-graduation. Spanning 18 campuses across New York City, it represents a larger and more diverse student body than any other debate team in the world. Recognized for tireless recruitment and practice, out of 275,000 enrolled students university-wide Trevor was the only one not in student government, alongside five in student government and several faculty and administrators, appointed by the CUNY Board of Trustees to serve on the 2017-2018 CUNY Student Activities Fees Task Force which, for the first time in decades, reviewed the university’s student activity fees policy infrastructure and ensured consistency with prevailing laws and best practices.


Trevor Colliton developed many additional relationships across the university debate community. Trevor debated or judged nearly every weekend on the American Parliamentary Debate Association (APDA) circuit and at numerous British Parliamentary (BP) competitions, including two national championships and two world championships. Trevor served as Chairperson for 1.5 years, and New York Regional Coordinator for 3 years, of the APDA Expansion Committee; nobody had ever served longer on an APDA committee. In 2018, Trevor won the Kyle Bean Award, which is presented to the debater who best embodies the qualities of Kyle Bean, a former Harvard debater who died in 2016; those qualities included being welcoming to new debaters, using debate to explore interesting topics, and enjoying debate in a way that makes the activity more safe for everyone else. Trevor served as a Chief Adjudicator (CA) for the 2019 North American Debating Championship (NorthAms), sanctioned by APDA and the Canadian University Society for Intercollegiate Debate (CUSID) and arguably the second most competitive debate tournament on the planet after the World Universities Debating Championships (WUDC).


Trevor Colliton feels the most fulfillment of all from teaching schools debaters. In Spring 2016, Trevor began coaching and judging Public Forum (PF) Debate at numerous elementary, middle, and high schools in communities that had previously been debate deserts. In September 2018, Trevor Colliton was hired by Achievement First Brooklyn High School, becoming familiar with Lincoln-Douglas (LD) Debate, Extemp, Congress, and Interpretative Events. Trevor is incredibly appreciative of the network and high school’s support for the debate program, and feels unbelievably lucky to learn from as brilliant and caring a teacher as DiCo. Trevor hopes to build up our scholars’ love for debate even further over the coming years at AFBHS!
