Our Team
Barbara Andrea Garza Guzman, LCSW
(she/her/ella)
Co-Executive Director
Operations & Programs
Read Bio▾Barbs (she/her/ella) is Co-Executive Director of the Transformative Justice Project of Colorado, where she leads operations and programs.
Rooted in the border between Matamoros, Tamaulipas, and Brownsville, Texas, Barbs came to Colorado for her Master’s in Social Work at the University of Denver. Now a Licensed Clinical Social Worker, she has spent nearly twelve years working across education, mental health, child welfare, and the criminal injustice system. Her goal has never been to make those systems slightly less harmful. It’s to build something better.
Barbs works in Spanish and English, through real relationships, and alongside young people, families, and communities rather than on their behalf. She has co-authored articles on antiracism and abolishing whiteness and serves as a peer reviewer for the journal Advances in Social Work, reviewing scholarly articles on whiteness, race, and antiracism.
She lives in Colorado with her husband and two tuxedo cats, to whom she is highly allergic.
Erin Pier, Ed.S
(she/her)
Co-Executive Director
Development & Communications
Read Bio▾Erin is Co-Executive Director of the Transformative Justice Project of Colorado, where she oversees development and communications. She also provides court advocacy and case management support through the Community Cares program.
Prior to joining TJP, Erin spent 14 years as a school psychologist in Aurora and Denver Public Schools, where she became passionate about the need for systemic change in education. She earned her undergraduate degree in Special Education from Saint Louis University, began her teaching career at Savio House in Denver in 2007, and holds an Education Specialist degree in Child, Family, and School Psychology from the University of Denver.
Throughout her career, Erin has been guided by a core belief: there are no bad kids, only unmet needs. As a mother of three neurodivergent children navigating dyslexia, ADHD, and hearing loss—and as someone late-diagnosed with ADHD herself—she understands how systems prioritize conformity over creativity, often leaving neurodivergent individuals feeling ill-equipped or unseen. She recognizes the privileges that enabled her own success despite these challenges, privileges too often denied to system-impacted youth.
As a co-founder of the Community Cares program, Erin has led efforts to dismantle the school-to-prison pipeline by providing holistic support to system-impacted youth. Her leadership integrates her background in mental health and education with an unwavering commitment to decentering whiteness and advancing antiracist practices in youth advocacy.
Erin lives in Denver, where she enjoys camping, traveling, hiking, baking, running, snowboarding, and playing drums with her husband, three kids, and two dogs.

Our Leadership Philosophy
Our Leadership Model
Historically, nonprofits concentrate power in a single executive director, creating inequitable hierarchies that value one person’s decision-making at the expense of collective wisdom and diversity.
At TJP, we challenge this model. Erin Pier and Barbara Garza serve as Co-Executive Directors, sharing strategic leadership and organizational decision-making. Erin focuses on development, communications, and external partnerships, while Barbs oversees programs, services, and operations. Together, they lead in collaboration with the Board of Directors and in accountability to the communities we serve.
Our co-executive model is an intentional step toward decolonization and shared power—countering the racialized, gendered, ableist concentration of authority that Western leadership structures have historically embodied.
