In Memoriam
Tchet Dereic Dorman, Senior Consultant
Our Friend, Mentor and Colleague

Tchet was a crucial and irreplaceable part of Blue Door. He served as our mentor and leader in transformational intergroup dialogue work. 

Tchet and Hillary facilitated countless dialogues together and offered intergroup dialogue facilitator training to professionals from community, K-12, and higher education institutions. Tchet’s desire was to see intergroup dialogue work happening everywhere.

Tchet's work reached people far and wide. He was an educator, administrator and organizational leader, having served as a university administrator and faculty member at 15 colleges and universities. He served as a leader in diversity, inclusion, and equity at a variety of institutions, including most recently as Senior Consultant for Diversity and Inclusion for the American Cancer Society (ACS). Previously, Tchet served as the Director of Diversity, Equity and Inclusion at Germantown Friends School, the Director of Diversity and Social Justice at Millersville University, the Director of the Center for Social Justice and Multicultural Education in the Office of Institutional Diversity, Equity, Advocacy and Leadership at Temple University, and as the Director of Multicultural Affairs at both Lebanon Valley College and Albright College. Tchet had a bachelor’s degree in Black Studies and Government from Oberlin College, and master’s and doctoral degrees in African American Studies from Temple. He also had a graduate certificate in Diversity Leadership from Temple, where he learned the tools of transformational social therapy that he used in his dialogue work.

We honor Tchet and the transformative work he did in the world.

Hillary Blecker, Founding Partner


Hillary helps groups accomplish their goals by building authentic relationships across barriers of race, class, gender, and other social identities. She’s a longtime leader of both dialogues and trainings, and a co-founder of The Blue Door Group and its predecessor, the Philadelphia Trainers’ Collaborative. Hillary has a decade of experience in occupational health and safety training, predominantly with immigrant and low-wage workers, where she learned that relationships and trust were the biggest internal obstacles to groups getting what they want. Now she leads dialogues that support organizations and individuals to address existing conflicts, locate barriers to engagement, and build trust together. She has a BA in Public Health Social Sciences from Johns Hopkins University, a Master of Public Health in Community Practice from the University of Washington, and a graduate certificate in Diversity Leadership from Temple University. As a Blue Door trainer, Hillary prioritizes connection, warmth, and flexibility in assisting groups to have productive conflict and get where they need to go.
