Our Team


Sandi Teeter

Owner and
Head of School

Sandi Teeter was born and raised in Austin, Texas. She studied Education at the University of Texas at Austin where she specialized in Math and Reading. Having been around construction her whole life, it was no surprise, her path lead her into homebuilding rather than education.

She moved to Houston after graduation where she transitioned from various accounting and purchasing roles to the land development and acquisition side of the homebuilding industry. In 2006, she and Scott moved their family to San Antonio, Texas. She spent several years as a VP Project Manager for a private builder and is currently a VP of Sales & Marketing Manager for a large public home builder.

Sandi & Scott are the proud parents of three beautiful children. Emily, William and Brian fuel our passion to continue our Hero’s Journey.


Scott Teeter


Scott Teeter, born in Washington, DC and raised in New Jersey and Philadelphia, considers himself a Texan. He graduated from Penn State University's Schreyer Honors College in 1989 with a degree in Finance. He worked in Dallas for EDS until he returned to Philadelphia to attend graduate school at The Warton School where he received his MBA with a concentration in Finance and Strategic Management. During his graduate studies he spent 6 months in Sydney, Australia at the Graduate School of Management.

After graduation he worked in business development for Frito Lay in Dallas and supported one of their largest product launches. He followed his mentors to Centex Homes where he acquired numerous companies across the country. He found his calling when he combined finance, land acquisition, community planning and development. This passion moved him to Houston and eventually to San Antonio. Scott currently works for a public homebuilder as the VP of Land Acquisition and Development for San Antonio and Austin.

His love for family and community inspired him to start Acton Academy San Antonio.


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".


Jeff Sandefer


Jeff Sandefer lives a dual life as an entrepreneur and a Socratic Guide.
