People were always asking San Francisco attorney Mae O’Malley how she lined up so much contract legal work as she juggled continuing her law career and raising three children. Her secret: As a former in-house counsel, she had built up a clientele, including Google Inc., and was ready for solo work after her third child was born.

Last year, O’Malley, 34, created a company built on her strategy, giving her the opportunity to share the trick with the many other women who have asked about it. She opened Paragon Legal Group in September and already has 20 lawyers working for her on either a full-time or part-time basis, 90 percent of whom are women.
