In the early 1990s, a group of women who were partners in what was then Coopers & Lybrand met to form a study group. At first they gathered monthly to discuss their careers and how to provide leadership in the firm and in a traditionally male-dominated industry. But after a few meetings, the women began to realize that they were meeting to discuss their work and their lives in general. They developed a strong mutual trust, and found they could rely on each other for frank feedback as they worked on strengthening their leadership abilities.
