About collective impact solutions
Who We Are
Collective Impact Solutions (CIS) is a Technical Assistance Center bridging community and systems to build integrated Systems of Care anchored in a "No Wrong Door" approach—where every entity becomes an entry point for families. We work with schools, cities, counties, community-based organizations, and health plans to co-design solutions with parents, youth, and partners with lived experience, driving sustainable and scalable change.
At the center of our work is the Bridges to Care Respite Center—our direct service arm and Design-to-Implementation Hub where the System of Care and No Wrong Door model is implemented and refined in real time. Through this approach, we build the capacity needed for sustainability, scale, and lasting impact for families and communities.
We don't just consult families—we position them as co-designers, decision-makers, and leaders. Parents and youth with lived experience drive every initiative we launch, from leadership fellowships to cross-sector partnerships to blended funding models that combine Medi-Cal, education dollars, and philanthropy.

Our leader and co-founder
Dr. Rebecca Celes Mendiola, CEO & Co-Founder 25+ Years Transforming Systems From Within and Beyond
Dr. Mendiola didn't just study systemic change, she lived it. After 23 years leading transformation efforts as an Assistant Superintendent, Director, and Coordinator across multiple school districts, she made a strategic decision: systems change faster when pushed from the outside with inside knowledge.
Her Unique Perspective:
- Co-founder of the California PBIS Coalition
- Established and directed PBIS Technical Assistance Centers in Santa Clara and San Diego Counties
- Led multiple student services departments ensuring equitable access for all students
- Expert in Mental Health, Behavior Intervention, and System Coordination
"I spent decades working within government systems. Now I use that insider knowledge to help communities navigate those same systems more effectively. The difference is night and day when communities have someone who truly understands how government works."
