The members patrol Chinatown, wearing green vests, helping with everything from de-escalation to harm reduction and more.
"We clean the street, we do graffiti abatement, and some of these folks here came on board because they wanted to give back to their community," said Sakhone Lasaphangthong, a Chinatown Community Ambassador.
The program currently has three community ambassadors on staff and two volunteers.
They hope to add more people with fundraising and community support.
