Sylvia Acevedo is a trailblazer in business and tech. She was one of the first Hispanic students to get a master's in engineering from Stanford, she worked for years as a Silicon Valley executive, and on top of that, she's an actual rocket scientist. As CEO of Girl Scouts, Acevedo is reinventing the organization to focus on STEM—science, technology, engineering, and math—and she hopes more young women will follow in her footsteps. Boy Scouts may now be recruiting girls too, but she says it'll never compete with the opportunities Girl Scouts offers.
