Working moms fill many of the top jobs at Bain & Co., with role models including North American Chief Financial Officer Mary Welch, a mother of two, and Global Chief Marketing Officer Wendy Miller, a mom of three.

To better understand how this management consulting firm treats moms (who are 17% of its employees), just listen to their stories. “I’ve felt incredibly supported,” says manager Cate Shainker, a mother of two, who worked as little as three days a week for nearly two years and still scored a promotion. Senior knowledge specialist Crystal Liebling, who’s raising a toddler, says her colleagues help her work from home two days a week. “We all lean on each other,” she explains. Partner Elizabeth Spaulding, a mom of two, praises a global sponsorship initiative that allows female partners, principals and managers to be mentored by other partners and directors. “Our conversations are about much more than work,” she notes.
