Mike Likier, Ph.D.

Mike has been a racial justice activist since 1991.  The unrest in Crown Heights that August, followed by a course in Racial Identity and Mental Health taught by Robert Carter, Ph.D. set him on his journey.  Mike has been involved with the National People’s Democratic Uhuru Movement, People’s Institute for Survival and Beyond (PISAB) and in several faith based initiatives.  As a psychologist, he brings a justice lens to his therapy practice and he is involved with training therapists in multicultural competence.  Further, he consults with organizations that are working toward realizing these values. Mike was a participant in the White People Confronting Racism workshop in 2011 and returned as a facilitator in 2016.  “Ron Chisom, founder of PISAB, once told me that if you bring 2 White people together to talk about undoing racism you are doing something important. I’m honored to be part of a team that is engaging hundreds of White people in this struggle”


Cara Tratner (she/they)

Cara is a queer femme weirdo, a community organizer, and a harm reduction practitioner who dreams of a world without prisons and police. She is a core organizer with the Philadelphia Community Bail Fund, and has been organizing to shut down jails and to end cash bail for 5+ years in Philly. She has worked in direct-service in reentry, harm reduction, HIV/AIDS and housing justice. She is grateful for all her mentors and for Black feminist movement leaders, who pushed her to grow a radical imagination and to believe that another world is possible and is on her way. Cara has found the work to unlearn the trauma of white supremacy to be deeply transformative and healing spiritual work. She brings a goofy sense of humor, a love of music and singing, and a heart-centered presence to facilitation. When not facilitating or organizing, she can be found caring for her plants and her cat-child Dracula.
