Ambassador Program

Ambassador Program

The Obesity Society Ambassador Program allows the Society to stay connected with the broader professional obesity community, remain aware of nascent opportunities, and establish lines of communication to drive us all forward. A member of TOS leadership is appointed to coordinate with each of these organizations to maximize its external interactions with a more proactive stance. This is an approach that allows TOS to make healthy choices that fulfill the promise of collaboration while protecting the Society's core values and brand.
