Sylvia Acevedo

Sylvia Acevedo

CEO, Girl Scouts of the USA 

A lifelong Girl Scout and career G.I.R.L. (Go-Getter, Innovator, Risk Taker and Leader), Sylvia Acevedo was appointed CEO of Girl Scouts of the USA in May 2017, having served as a member of the GSUSA Board of Directors from 2009 to 2016 and an officer and member of its Executive Committee. 

As a young girl growing up in New Mexico, Acevedo’s Girl Scout experience taught her how to create opportunities, to dream big, and to reach for the stars – both literally and figuratively – and nourished her love for math and science that would culminate in a career as a rocket scientist, engineer, and award-winning STEM entrepreneur. Acevedo served in executive and engineering roles at leading technology companies such as Apple, Dell Computer Corporation, Autodesk Inc. and IBM. She began her career as a rocket scientist at NASA’s Jet Propulsion Laboratory where she worked on NASA’s Voyager II mission. She played a critical role in helping NASA learn about Jupiter and its moon’s Io and Europa by developing unique algorithms to analyze the data Voyager II sent back. 

Acevedo served on the founding board of the Ann Richards School for Young Women Leaders in Austin, Texas – the largest all girls public school in the nation and co-authored the Houghton Mifflin Harcourt Family Engagement curriculum. She is the author of Path to the Stars, an aspirational memoir for middle school students that focuses on her own journey of perseverance, hope and achievement against the odds. 

A recipient of numerous awards such as the Girl Scouts of Central Texas Woman of Distinction in 2013 and national recognition on U.S. News and World Report’s list of the top 100 American women in STEM in 2012, Acevedo was one of the first Hispanic students, male or female, to earn a graduate engineering degree from Stanford University – an M.S. in industrial engineering. She holds a bachelor’s degree with honors in industrial engineering from New Mexico State University.
