LAURA SANDEFER

Laura lived on both US coasts and in between as a child, then settled into Vanderbilt University for her undergraduate studies in the College of Arts and Science. After being awarded the highly competitive Walter Wattles Fellowship at Lloyd’s of London, Laura worked in the aviation insurance industry in New York City. Deciding to follow her calling into the world of education, Laura returned to Nashville and earned her Master of Education at Peabody College. This led her to her work at the Oklahoma Arts Institute, creating fine arts education programs for teachers and talented high school students.

Laura married Jeff Sandefer and is the happy mother of Sam and Charlie and step-mother to Taite. It is the inspiration of these children that led Laura and Jeff to co-found Acton Academy.

Her greatest hero is her mother who was a Master Teacher. Her wisest mentor is her father who sent her off to college with two words of advice: "Be curious".
