The Ambassadors are a select group of volunteers who actively serve as the goodwill arm of the Chamber. Considered one of the best ways to gain an in depth understanding of how all the facets of our Coastside community work together, the Ambassadors Committee offers opportunities to connect, engage and inspire other businesses on the coast. Responsibilities include promoting the Chamber membership, attending Chamber events, and marketing the Chamber and its causes. Ambassadors serve as an extension to the Chamber staff and on occasion as a liaison.

Meets: Second Wednesday of the month at 5:00pm
at Vinoteca, Half Moon Bay

Committee Members:
