Traditional outreach wasn't reaching Denver's most vulnerable residents. CCG designed and launched an Ambassador Program that partnered with 12 community-based organizations to connect Latino, Black, and displaced populations with Denver Water's Lead Reduction Program. By embedding outreach within existing community events and trusted networks, we created culturally appropriate pathways to participation that traditional methods couldn't achieve. The numbers tell the story: 5,000 community touchpoints and a 93% behavior change success rate in Hispanic communities.
