Meet Our Educators
Christina Callaway, M.A.
Director and Co-Founder
Upper Elementary ELA and Spanish
"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.
Stephen Michalik, M.Ed.
Co-Founder and STEM Coordinator
G3-6 Math and Science
"The joy of teaching comes from witnessing my students make connections across various content areas. I enter my classroom each day with the mindset that all students can learn. My goal is to develop students to ask questions and think about mathematics in the world around them. I am thrilled to share my passion for STEM learning and innovation."
Stephen Michalik is a graduate of the University of Northern Colorado with a Master’s in Interdisciplinary Studies and Mathematics and has been in education for over 15 years.
Mr. Michalik recently participated in Texas A&M's Texas Regional Math Collaborative which focuses on project-based learning, algebraic thinking and problem-solving. He was also selected to participate in the Texas A&M Innovative Technology Experiences for Students and Teachers, a collaborative research project promoting STEM through the use of building automation applications, connected devices (commonly called the Internet of Things) and 3D printing. He has presented at both district and state mathematics conferences on technology and its influence in the math classroom.
Mr. Michalik recently won a STEM grant from Rice University to support our Robotics program through a "Breaking Barriers" series of robotics challenges and competitions in partnership with Journey School, a school for students with special needs and different abilities.
When he is not in the classroom, Mr. Michalik stays active in the community: training for triathlons, coaching swimming, and mentoring prison inmates at the Wallace Pack Unit in Navasota.
Dr. Nicole Puig-Herz, Ph.D.
Language Program Coordinator
"I believe deeply in the transformative power of mentoring relationships and individualized instruction. My goals in the classroom always include developing students' confidence and preparing them for real-life cultural and linguistic situations they will encounter. At ANCS, I work hard to meet each child's needs and interest in Spanish, and I challenge them to develop their fluency in speaking, literacy, and cultural awareness. I am passionate about expanding students' global worldview!"
Dr. Nicole Puig graduated Magna Cum Laude with Dual Honors Baccalaureate degrees from Virginia Tech in Spanish and International Studies, with minors in French and European Studies. After living in Germany for a year, she earned her Ph.D. from Cornell University in Romance Studies with a concentration in Hispanic Literature and a subspecialty in Catalan Studies.
Dr. Puig has taught ages 4 to adult in a multitude of settings (Bryn Mawr College, Cornell University, community college, individual and group private classes), before shifting to private school. She has nearly two decades of experience teaching language, literature, writing, cultural studies, and film. Dr. Puig speaks eight languages with varying levels of fluency, of which she has taught four: Spanish, Catalan, French, and English. She has published academic articles and translations and has presented in academic conferences.
As a Cuban-American who is also raising multilingual children, Doctora Puig relates viscerally to the opportunities and challenges of raising children bilingually in the U.S. She especially loves encouraging heritage speakers to embrace their other culture and to challenge themselves to achieve new levels of proficiency in Spanish.
In her spare time, Dr. Puig enjoys running, cooking, singing, playing the piano, training her rambunctious dog Bandit, and traveling. She is passionate about women's education and health, has volunteered with Refugee Services of Texas, and has traveled to Peru several times as interpreter for her church. She is also currently serving on the Global Missions Committee at her church.
Dr. Puig believes everyone can and should be exposed to at least two languages and have opportunities to engage with other cultures. The earlier the better, but it is never too late.

Claudine Dehaquiz, M.Ed.
"A child's character, beliefs, values and culture should be respected. Their curiosity, strengths and talents should be nurtured. Love, kindness, solidarity, honesty, goodwill and honor should be taught and motivated intrinsically not only at home but in any learning institution and environment. But above all, love is the key to every success as God has given us that example through His son Jesus Christ."
Maestra Dehaquiz was born and raised in New York with parents that immigrated from Colombia, South America. After graduating from Nyack College in Education and History with a minor in Bible, she decided to head off to Colombia to learn about her parents' culture and language. She met her husband, William, in Bogotá, where two years later their daughter Carolina was born. The family later moved to Mexico City, and the following year her son Juan Camilo was born. During her time abroad in Colombia and Mexico, Claudine taught in several bilingual schools. The family later decided it was important for Caro and Juan Camilo to experience school in the USA and the Lord led us to Texas.
Maestra Dehaquiz has taught Bilingual Education in Texas for more than 10 years. After her Masters degree from Lamar University in Education Administration, she became a Bilingual Instructional Specialist at Magnolia ISD.
