Training Team
Chuck Calderilla
Statewide IPS Trainer & Fidelity Assessor
Chuck is a counselor-in-training who integrates lived experience, scientific insight, and cultural awareness into a supportive and empowering counseling approach. He is pursuing a Master of Science in Clinical Rehabilitation Counseling at Portland State University and is a recipient of the 2026 NBCCF Minority Fellowship for Addictions Counseling. He also holds a BA in Biology with a concentration in Molecular Biology and Biopsychology from Austin College.
As a multiracial professional with Indigenous, Latine, and Black identities, Chuck embodies the full spectrum of what BIPOC representation means in behavioral health—not as an acronym, but as a lived reality. His background navigating working-class systems informs a strong commitment to trauma-informed, culturally grounded, and justice-centered care. Chuck believes that each person carries a story of adaptation and survival, and he works to help clients uncover resilience already present within their communities and identities.
His approach blends narrative therapy, existential exploration, addiction counseling frameworks, and an ecological understanding of mental health that considers environment, experience, and biology together. Chuck volunteers with WeBelong and NW Noggin, bridging neuroscience, creativity, and culturally grounded belonging for underserved youth and families in Portland.
Chuck is preparing for a future that includes clinical practice, community advocacy, and research, with goals of pursuing a PhD and teaching at the college level to help develop the next generation of culturally attuned counselors.
