Erin Turri


Born and raised in Michigan, Erin has always had a passion for entrepreneurship. She owned businesses since she was a child and through her college years, while she earned a Bachelor of Science as an Anatomic Pathologists' Assistant. After eight years in the medical field, she followed her calling to design and build an independent coffee shop from the ground up while  remaining in her profession. Four years later, a one year old and a newborn became her top priority and she sold the business. Now eight and seven, her daughters have become the inspiration that fuels new-found passions. Responding to a call to action, Erin found herself searching for a school that would empower her daughters and embrace their unique selves while preparing them to be caring, contributing community members. Finding the perfect fit in Acton Academy, she pursued ownership to ensure them the stability of this learner-driven education. Armed with the experience and knowledge that Acton philosophy can be life-changing for many children, she is determined to help families and children realize their hero within.

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".
