Our Teachers

Kathy Preston

Kindergarten Teacher


Kathy Preston grew up on a farm west of Montgomery, Alabama. There she learned to love animals and to work with and for her family. She is married to Harold Preston, and has three grown children: Dustin, Morgan, and Luke.

Almost 20 years ago she realized that she wanted to “make the world a better place.” So after much prayer and soul searching, she resigned from government work to pursue her teaching career. She has never regretted her decision. After 11 years teaching in Marietta, Georgia, she landed a job here at OAKS and the move has been a blessing for her and her family.
