At Lumen Intervention Service, we are honored to walk alongside families as they navigate some of life’s most difficult moments. Built on the foundation of the Process Intervention Model, our work is rooted in compassion, clinical integrity, and a deep respect for the transformative power of human connection. Designed by Kenneth Sieczkowski, a pioneer in the behavioral health field, this model offers families a thoughtful and sustainable alternative to traditional intervention—focusing on awareness, accountability, and lasting recovery, rather than ultimatums or crisis-driven pressure.

With over 30 years of experience supporting individuals and families through addiction, mental health, and systemic challenges, Kenneth brings both real-world wisdom and deep clinical insight to every engagement. He has had the privilege of serving on the Association of Intervention Specialists board for more than 15 years, two of those as Ethics Chair, helping shape the ethical and professional standards that guide the field today. His background spans the full continuum of care, including developing residential treatment programs, directing outpatient services, and leading psychiatric interventions. While these roles reflect a deep level of expertise, it is the trust of families, the courage of clients, and the opportunity to serve during vulnerable moments that remain the greatest honors of this work. At Lumen Intervention Service, we approach every family with humility, respect, and a belief in their capacity to heal. We are proud to be a leader in the intervention field.
