Who We Are
Incredible Credible Messengers, Inc. (ICM) is the only NYC-based organization dedicated to normalizing restorative practices as both a lifestyle and standard approach for violence interruption, youth leadership development, and community building. By leveraging the power of relationships, ICM fosters individual growth and sustainable community transformation. Through a phased approach, ICM introduces Tier I restorative practices to cultivate positive environments and provide basic training, and then progressively equips youth with advanced Tier II and III skills for mediation, advocacy, and systemic change through experiential learning.
Since 2017, ICM has conducted comprehensive peacemaking, placemaking, and placekeeping efforts throughout NYC’s public spaces. Youth participants are activated to lead outreach, advocacy, and social impact projects while hosting events that promote nonviolence and social equity. ICM’s innovative programs—Purposeful Partnership Program (PPP), Incredible Warrior Ambassadors (IWA), SELF-Construction, and the Alumni Program & Youth Advisory Board (YAB)—focus on restorative justice, essential skills development, grassroots organizing, and community mobilization. Complementing these initiatives are services such as training and professional development workshops, parent and caregiver coaching, support groups, and consulting for schools, agencies, and corporations. These mission-aligned efforts allow ICM to foster healing, inspire community leaders, and transform lives through a commitment to trust, accountability, and collective growth.

History
ICM's inception stemmed from a course that ICM’s founder, Ms. Jackson took while attending the Institute for Transformative Mentoring, based at The New School. She and her colleagues, who were employed as credible messengers, were challenged to dig deep within to identify their traumas, and then brainstorm how to provide more effective, trauma-informed reentry services in their work. Recognizing the inadequacy of services offered elsewhere – especially when delivered by individuals without lived experience in the justice system – the founders aimed to address the challenges faced by returning community members. This endeavor was motivated by a desire to prevent re-traumatization from mirroring dynamics experienced during incarceration.
ICM was founded by Tyisha Jackson, Steve Exantus, and former business partners in July 2017 and was granted its official 501(c)3 status on December 28, 2017. All founders have firsthand, lived experience with the criminal justice system and are trained in restorative practices including restorative justice, relationship restoration, and trauma-responsive care. In early years, ICM leadership and volunteer staff leveraged their expertise to engage resident leaders, local decision makers, and other community stakeholders to advocate for essential support and healing-based resources that benefit vulnerable families, communities, and returning citizens. The executive team comprises professionals well-versed in the nexus between personalized support networks and recidivism. Drawing on their diverse backgrounds, education, and personal experiences, ICM team members help participants navigate complex personal, social, and economic barriers to healthy and safe dynamics to overcome internal, family, and neighborhood discord.
Currently, ICM is focused on serving youth from disadvantaged backgrounds, and ensuring their stakeholders are positioned to support their growth. We understand the importance of youth healing and development, as well as the positive changes that they create as leaders. At ICM, our youth participants lead the charge with grassroots advocacy, community organizing, youth mobilization, and recruiting efforts. They are highly effective in generating positive outcomes when they are nurtured, supported, and equipped with resources because they have the freedom to operate from a safe, secure, and whole internal space.

we can solve it, and how we can help our community,
learning how to do new things and have new
experiences, doing things I wouldn't normally do."
