Laura Sandefer, Advisor
Laura is cofounder and head of school of Acton Academy (Austin). Raised by a science teacher and minister, Laura lived on both coasts and in between as a child and then landed at Vanderbilt University for her undergraduate studies in the College of Arts and Science.
After working in London and New York City in the aviation insurance business, Laura yearned to follow her heart into the world of teaching. She went back to Vanderbilt's renowned Peabody College and received her Master of Education. This led her to work in arts education at the Oklahoma Arts Institute. Laura later married Jeff Sandefer and has two sons and a stepdaughter. It is the inspiration of these children that led Laura and Jeff to cofound Acton Academy.
Her greatest hero is her beloved late mother, who was a master teacher as none other. Her wisest mentor is her father, who sent her off to college with two words of advice: "Be curious."
