Our Teachers

Kathy Preston

Kindergarten Teacher

Kathy Preston grew up on a farm just west of Montgomery, Alabama. There she learned to love animals and to work with and for her family. She attended the church school in Montgomery, Georgia-Cumberland Academy, and Southern Adventist University, and recognizes the sacrifice and privilege it is to have an Adventist education. 

Twenty-eight 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 teaching position at OAKS. During her career, Ms. Preston has taught Kindergarten, First Grade, Second, Third, and Sixth grade.
