Please welcome Marie Stevenson and Chris Stowers to their new roles.

Christopher Stowers, Treasurer
Christopher Stowers brings a deeply personal and professionally grounded commitment to mental health and substance use advocacy to his role as a Board Member of Trillium Centers. Christopher’s passion for this work is rooted in lived experience. Growing up in a family impacted by mental health challenges, he witnessed firsthand the complexity, resilience, and quiet strength required to navigate these realities. Those early experiences shaped his perspective, instilled lasting empathy, and motivated him to help reduce stigma while expanding access to meaningful support and care. Professionally, Christopher serves as a Relationship Manager within the substance use and mental health field, with more than 15 years of experience spanning healthcare, behavioral health, finance, and business development. His work focuses on building sustainable partnerships, strengthening referral networks, and bridging gaps between clinical care, community resources, and the people who need them most. He is known for his ability to connect organizations through trust-driven, human-centered relationships rather than transactional approaches. In addition to his role with Trillium Center, Christopher is actively involved in mental health advocacy and education through media, community initiatives, and board service, including his work with Zero Overdose. He is also the founder and co-Creator of Mind Split Cafe, a platform dedicated to honest conversations around mental health, substance use, recovery, and wellness. Christopher is deeply committed to advancing compassionate, evidence-informed approaches to care. As a board member, he brings a blend of strategic insight, relationship-focused leadership, and lived understanding—guided by the belief that mental health is not a side conversation, but a foundational component of overall well-being.
