Twenty-one years ago Barbara Hauser and Suzy Peterfriend had an informal meeting in New York of several key advisers to well-known family offices. The meeting, arranged by Suzy, had as its purpose to introduce Barbara to other key advisers as she began a new role advising a billionaire and his family office on how to keep his multitude of businesses under family control, for generations and with harmony. That small meeting grew into a pattern of similar meetings, with its own name ?The Family Advisory Council?. In their article the authors explain how the meetings work and why they have been so successful. The group is now in its 21st year of meetings. Family offices are often isolated; these discussions provide a forum for sharing information and experiences. Their hope is to encourage other groups, around the world, to form similar groups. They are happy to be a resource.
