Sowell strives to ensure all students are loved at Peach Creek Elementary and that they all become learners inside and outside of the classroom. She supported teachers when Peach Creek Elementary piloted the Blended Learning model to ensure all teachers were successful and that every student's learning experience in the Blended Learning model was accomplished. She is passionate about students receiving learning experiences that allow them to extend their understanding of concepts while making meaningful connections that will mold them into lifelong learners.

Sowell fosters positive relationships with teachers, students, and parents. She celebrates all students in and outside the classroom for their individual strengths and talents; therefore, you have likely seen her around the community at UIL competitions, fine arts showcases, robotics competitions, the baseball field, or even at the county livestock shows. Sowell met her husband, Wayne, at Splendora High School, and they have been married since 2011. They have two boys who currently attend Peach Creek Elementary. Sowell seeks to capture every child's heart and, as a mom, has embraced Capturing Kids' Hearts practices within her own household.
