Mission: The mission of the Ambassadors Committee is to aid the Membership department in welcoming new members, retaining existing members, and to support the mission of the Petaluma Area Chamber. Members represent a diverse group of business owners, managers and agents of their organization.  

Ambassadors may attend the annual California Ambassadors Rally and periodically, the group selects a member to be featured in the Ambassador Profile column in the Petaluma Business to introduce the membership to current Ambassadors.  This group meets once a month to review upcoming events and act as the hosts for events such as:

  • Business After Hours Network mixers
  • Chamber Luncheon Series
  • Community Awards of Excellence
  • Business Expo
  • 5th Tuesday Lunch Mob events
