"I want to teach students to value the process over the end result and to see failure as opportunities for growth and reflection. I want them to know that anything worth doing will require perseverance and a determination to accomplish the task at hand. The reward is in their own personal satisfaction and seeing the results of their pursuit of excellence."
Christina Callaway was born in Manila, Philippines, and moved to Texas as a junior high student. Her experience as a young student at international schools helped her develop an appreciation for other cultures and languages. This eventually led to an adventurous career teaching for a decade in international schools in South America and the Middle East. She has lived in six countries, is fluent in Spanish and speaks conversational Portuguese and Tagalog.
​
Ms. Callaway has been in education for over 15 years and has taught a variety of subjects and grade levels throughout her career. She holds a bachelor’s degree from Smith College and a master’s degree in Educational Leadership and Administration from The George Washington University. Ms. Callaway has served as International Baccalaureate Coordinator, Assistant Principal, and Principal in the private school sector.
​
Ms. Callaway's desire is for every student at ANCS to know how much they are loved and uniquely made by God. Her own uniqueness comes out through her love of exploring new places, bartering in flea markets, singing to oldies, and spending time with her husband and two children.

Erica Payne was born in Syracuse, New York. She traveled the world as an Air Force brat and then an Army wife, before landing in Houston in 2016 along with her husband, Kenny, their five kids and various pets.

Christ.
