Brenda joined the CTCS family in 2014 and serves as our Head of School. She graces our halls with a spirit of encouragement and an amazing capacity of love. Brenda has a passion for nature and the great state of Texas. She enjoys taking day trips, and is currently attempting to visit all the historical forts within the state. She considers herself a connoisseur of hamburgers and visits local burger joints everywhere she travels; her favorite as of today is in Lajitas, Texas at Candellia inside the Lajitas Golf Resort.  Brenda has also dreamed of traveling with her family to Ireland and Scotland. She and her husband of 43 years (Bob) have three grown children (Tamara, Tyler, and Rance), two precious daughter-in-loves (Kim) and (Pam) a son-in-love (Chris), one granddaughter (Harper Grace) and two grandsons (Ridge Levi and Cash Townes).

“Every morning I feel I need to pinch myself. I am overwhelmed with the blessing of knowing God has given me His mercy and grace and a new day to share His love with His children. Are you kidding? He chose me to work with His most precious creation – His children? What an honor and a great joy.”

Nabil “Bill” Diab has been at CTCS for over five years, starting as a 5th grade teacher. Along with his duties as an Elementary School Principal, Bill taught 4th and 5th grade in addition to high school Bible classes.

Bill is originally from Lebanon and came to the United States over 40 years ago. Lebanon is an amazing place, known for its beauty, rich in diversity and history.

“I can’t express enough to you how blessed I am for the wonderful life I have received through our Lord and Savior. When I cried out for Him, He heard me. I’m always ready to share my testimony with you.”

Kelly serves as our Preschool Director and has been at CTCS for 20 years.  She and her husband, Eddie, have been married for 27 years and have two children.  Taylor graduated from CTCS in 2018 and Rhett is currently in ninth grade.  Kelly taught first grade at CTCS for 18 years before transitioning to the role of Preschool Director and Admissions.  Her classroom was affectionately called the “Humphrey Honeybees” and she loved watching through the years as the honeybees grew.  With this new role, she has the joy of seeing former students as well as meeting new families.  Her new favorite thing is to talk to new families about CTCS and why it’s so special.   When not at CTCS, Kelly enjoys spending time with family and friends, cheering on the Texas Longhorns, and dreaming about future trips.

Karen has been a part of the CTCS family since 1988 and serves as the Dean of Students, Cheerleader Sponsor, Retreats Administrator, and Speech & Academics Sponsor. She and her husband of 45 years (Bobby) have three children and ten grandchildren. Karen’s commitment and love for CTCS is obvious as she dedicates herself to its missions and its families. When she does have down time, she enjoys watching movies, eating popcorn, relaxing by the pool, watching the stars, and playing with her grandchildren. She also hopes to explore the other side of the ocean and take a tour of Italy, Paris, England, Ireland, and Scotland.

In the fall of 2020 Sarah joined the CTCS administration as the Director of Student Life. In this new position, Sarah continues to coordinate the CTCS Retreat Program, in addition to the CTCS Mission Trip Program, the CTCS Ambassador Program, and the Reimagined Lion Leadership Program. While she is developing more projects to enhance the CTCS student experience, Sarah enjoys being available to students as she works from campus three days a week.

Sarah and her husband, Stephen, have been married for over 25 years and have three children. Jack, their oldest son, graduated from CTCS in 2018. Caroline, their daughter, graduated from CTCS in 2020. Sam, their youngest son, is currently a sophomore at CTCS.

In 2004, Sarah and her husband, Stephen, enrolled their son Jack in the CTCS Pre-K 4 class. After a year of involvement in CTCS as a parent, in 2005 Sarah was asked to join the CTCS school board. Sarah served CTCS as a board member until 2014.

Coach Johnston is entering his seventh year at Central Texas Christian School. He previously served as the Head Basketball Coach and Football Offensive Coordinator. He attended the University of Mary Hardin-Baylor. While there Coach Johnston played football as well as spending time as a student-assistant for the basketball program.
Leif is married to his wife Morgan, and they have one beautiful daughter, Lennon. He is thankful to God for their support in understanding the time and energy that goes into transformational coaching. Athletics has been an integral part of Coach Johnston’s life, and has taught him many lessons that may have otherwise gone unlearned. He truly believes that what is learned on the field, court, diamond or track directly relates to the adversity that each young person will ultimately face in their lives. “We merely want to use athletics as an avenue in giving them tools to handle adversity in a way that Glorifies Christ,” says Coach Johnston.
CTCS Athletics strives to compete with honor as we represent Christ first and foremost. Having the opportunity to further His Kingdom by the way we act, talk, and perform is the most satisfying aspect of what it means to be a coach.
