About Collective Impact Solutions
Who We Are
Collective Impact Solutions (CIS) is a Technical Assistance Center helping communities build integrated Systems of Care through a No Wrong Door approach—where every organization can be an entry point for families. We partner with schools, cities, counties, community-based organizations, and health plans to connect systems and co-design sustainable solutions that make it easier for families to access the support they need.
At the center of our work is the development of the Bridges to Care Respite Center, our emerging Design-to-Implementation Hub that will bring the No Wrong Door model to life in a community-based setting. Across all of our work, parents and youth with lived experience are co-designers, decision-makers, and leaders, helping shape solutions that are responsive, sustainable, and built to scale.

Our leader and co-founder
Dr. Rebecca Celes Mendiola, CEO & Co-Founder 25+ Years Transforming Systems From Within and Beyond
Dr. Rebecca Celes Mendiola didn’t just study systems change - she lived it. After more than two decades leading transformation efforts within public systems as an Assistant Superintendent, Director, and Coordinator across multiple school districts, she made a strategic decision: systems change faster when driven from the outside — by someone who deeply understands how systems operate from within.
Dr. Mendiola is the CEO and Co-Founder of Collective Impact Solutions, where she partners with districts, counties, cities, and community organizations to design and implement integrated systems of care through a No Wrong Door approach.
With over 25 years of experience across education, mental health, and systems leadership, she brings deep expertise in aligning systems to improve access and outcomes for children and families.
She is a Co-Founder of the California PBIS Coalition and established the PBIS Technical Assistance Centers in both Santa Clara and San Diego County Offices of Education.
“I spent decades working within government systems. Now I use that insider knowledge to help communities navigate and transform those systems more effectively. The difference is powerful when communities have someone who truly understands how systems work — and how to change them.”
