Meet Your Expert Training Team

Comprehensive Expertise for Complex Hoarding Intervention

The Professional Certificate training team brings together nine accomplished experts whose diverse backgrounds encompass clinical practice,  trauma-informed care, family support, harm reduction, housing stability, case management, and multidisciplinary community response. Each trainer contributes a distinct area of knowledge and a unique professional perspective, creating a coordinated learning experience that addresses the full complexity of hoarding situations rather than approaching them through a single discipline or intervention model. Individually, they are recognized experts in their respective fields; together, they provide an exceptional depth and breadth of advanced education. This collaborative instructional approach offers participants comprehensive, wraparound training that connects assessment, engagement, intervention, safety, housing preservation, coordinated case planning, and sustainable community response, equipping professionals to manage challenging cases with greater knowledge, confidence, and effectiveness.
