EVP, Walmart International 

Children: Two

Ruiz began her career at Walmart in 1992 as a store management trainee and worked her way up to the C-suite through hard work and determination.

Now, as EVP of Walmart International, she is "dedicated to giving back through various diversity and mentorship programs," writes Working Mother. 

Ruiz told the Hispanic Association on Corporate Responsibility: "Looking back there were so many people in my career who chose to help me, who chose to support me, and took the time to do that because they had an interest in me. It's more of a personal responsibility than a professional one. It really is about giving back considering what you've received."

The Facebook executive and best-selling author of "Lean In" is "building a movement toward gender equality in the workplace," says Working Mother. She even launched a new initiative, "Lean In Together," targeting men and their role in the gender equality equation.

In a recent conversation with Nate Silver from FiveThirtyEight, she said: "When we get to more equality in our homes we have happier marriages, happier relationships and more successful, happier and healthier children."

This powerful mom, who oversees one of the largest money management operation in the US, with more than $2.5 trillion in assets, was named the most powerful woman in finance by American Banker.

What's more, says Working Mother, "she's empowering fellow women in finance with two programs aimed at giving women in the industry a greater range of opportunities for career advancement."

Erdoes explained to American Banker why she founded these programs: "Women fall out of the workforce during years where they wanted to do other things in their life, pursue a different job track or raise a family. When they're ready to return, they don't have a natural way of coming back into the industry."

Your tribe of people, they are out there in the world. Waiting for you.
