She spent a number of years as a campus minister in Oklahoma, primarily at the University of Central Oklahoma. While serving as a campus minister, she also taught numerous university Bible courses. Janay came to CCS in 2008.

Believing strongly that the most important relationship in anyone’s life is their relationship to God, Janay feels both a sense of honor as well as great responsibility in teaching the Bible. It is her desire that every student will not only know that facts of the Bible, but will know through personal experience the God of the Bible. She prays that Bible will be more than just a class but will rather be the beginning of a lifelong passion for God and for His word. It is her prayer that students will be able to know and apply God’s word to every aspect of their lives and that they will be “thoroughly equipped for every good work” (II Timothy 3:17).

Janay is married to Michael and they have two children Zachery and Elisabeth. She loves spending time with her family and friends and is active in her church. She enjoys sports, playing games, shopping, cross-stiching and studying and teaching the Bible.

But thanks be to God, who always leads us in triumphal procession in Christ and through us spreads everywhere the fragrance of the knowledge of Him.

2 Corinthians 2:14

Joshua Beck

Joshua worked for Apple for several years before coming to CCS. Before that, he graduated from ORU with a B.A. in Theology and Philosophy. He grew up in a small town in Kansas, and married his girlfriend from high school in 2012.

Joshua is a firm believer in the truth and beauty of Christianity, and helping Christians apply it to their whole lives. Anything from art, to work, to economics, to technology, the Christian worldview has something to say about it. Which is why he especially enjoys shaping the way this Christian school, and its students, use their technology.

Outside of work, Joshua spends time reading, writing, listening to podcasts, or watching movies and TV with his wife, Sam.

But in your hearts revere Christ as Lord. Always be prepared to give an answer to everyone who asks you to give the reason for the hope that you have. But do this with gentleness and respect.

I Peter 3:15

Benjamin Patterson

Eric joined CCS in 2017. He has a B.A. in Christian Ministry from Tabor College and a M.A. in Theological Studies from Liberty University. Before arriving at CCS, Eric was a full-time Youth Pastor for over twelve years in Kansas and Nebraska.

Eric’s life purpose is to use his creativity and enthusiasm to love and encourage all people, with the hope that they might become believers who row into disciples that live on mission for the Kingdom of God. The primary way he enjoys doing this is by engaging students in a real and substantial way that gets them excited to learn more about God’s word and apply it to their everyday lives. Eric focuses on providing meaningful opportunities for his students to learn and succeed in the classroom and life.

Eric has been married to his church camp high school sweetheart, Dori, since 2004. They have three amazing children who also attend CCS. The strangest thing he has ever eaten is cow tongue and snail. When Eric isn’t teaching or coaching, he enjoys playing with his kids, date nights with his wife at Macaroni Grill, cheering for the St. Louis Cardinals and Wichita State Shockers, or simply enjoying a good movie.

Eric’s favorite verse is Ephesians 2:1-10 which describes the incredible work of Christ on the cross and salvation that is possible through faith.

For it is by grace you have been saved, through faith—and this is not from yourselves, it is the gift of God—not by works, so that no one can boast. For we are God’s handiwork, created in Christ Jesus to do good works, which God prepared in advance for us to do.

Let us love one another, for love comes from God. Everyone who loves has been born of God and knows God.

1 John 4:7

Renee Gunsaulis

Mrs. Gunsaulis joined CCS teaching 9th and 10th grade English in 2016. Having attended Christian schools her whole life, she is passionate about Christian schools and influencing the next generation to love God with all of their hearts and minds. Her true love is The Word and His Word, and as such she believes God has revealed himself to us as a communicator.

Her goal for her students is to see literature and composition as extensions of the stories God has placed in our hearts, having been made in his creative image. Mrs. Gunsaulis has taught English for five years in Christian and public schools. She has a BA in English with a writing emphasis from TCU (Go, Horned Frogs!) and is currently pursuing a Masters of Arts in Christian Education from Southwestern Baptist Theological Seminary, a lifelong dream of hers.

Mrs. Gunsaulis has lived in New Mexico, Texas, and, for the last three years, Oklahoma, which she loves. Her family includes her husband Mike and children Jacye (21), Kaitlyn (15), Grace (14), and John (11). When not at CCS, she enjoys co-leading a small adult class of young adults at her church with her husband, teaching women’s Bible studies, attending all of her children’s many band, athletic, and church activities, reading, and spending time with her two cats, George and Audrey, and her toy poodle, Berber.

Never be lacking in zeal, but keep your spiritual fervor, serving the Lord.

Romans 12:11

Jonetta Jonte, M.Ed.

Jonetta Jonte joined CCS in 2014. She has a B.A. in English from Southern Nazarene University and a M.Ed. in Teaching & Learning from Liberty University. Before coming to CCS, she taught in Oklahoma city Public Schools for 15 years.

Above all else, Ms. Jonte sees herself as a student who enjoys discovering new ideas in literature and delving deeper into the use of words in all types of communication. Her students are encouraged to become sesquipedalian and stump her as often as possible. When asked which her favorite book to teach is, it changes to the one currently being taught. She says it is unfair to ask an English teacher to choose.

Ms. Jonte has two grown sons who live in the area and she currently cares for her mother. While waiting on grandchildren, she devotes her attention to two spoiled Dachshunds, tries out new recipes, and watches lots of football.

This is a sacred day before our Lord. Don’t be dejected and sad, for the joy of the Lord is your strength!

Nehemia 8:10b


Nate Thompson

Department Chair

Mr. Thompson began teaching at CCS in 2018. After graduating from Hillsdale College in 2009 with a B.S. degree in History, he taught for 7 years in Christian schools in Tulsa and most recently in a rural public school. Nearing the completion of his M.A. in American History and Government, he is working on his thesis about how the religious beliefs of John Witherspoon and Thomas Jefferson shaped their understanding of the Declaration of Independence and how to best encourage the proper use of liberty.

Having taught 9-12th grades Oklahoma History, Government, US History, and World History, Mr. Thompson has come to appreciate the influence of big ideas and worldview in shaping the events and culture of different eras and groups. While many students will not pursue a vocation related to history, history offers a great opportunity to study worldview and even to reveal the ways our own culture shapes us – often without our knowledge. In what some have termed a post-Christian culture, it is important for students to become adept in applying a Biblical worldview in this context to be agents of change in the areas God will lead them. In addition to academics, Mr. Thompson enjoys the simply joys of interacting with students throughout the daily grind of the school year.

While in Christian schools, Mr. Thompson coached Cross Country and Track. As with many things, athletics can be a means of glorifying God through using one’s gifts or twisted to be used to bring glory to oneself. With this in mind, sports can be a great avenue to develop work ethic, perseverance, self-sacrifice, and, perhaps just as important, fellowship and the enjoyment of competition.

Outside of school, Mr. Thompson enjoys reading, playing and watching sports, and listening to podcasts and audio books. Most of all, he enjoys spending time with and relaxing with his wife, Melissa. They are eagerly expecting their first child in December 2018.

Therefore, I urge you, brothers and sisters, in view of God’s mercy, to offer your bodies as a living sacrifice, holy and pleasing to God–this is your true and proper worship. Do not conform to the pattern of this world, but be transformed by the renewing of your mind. Then you will be able to test and approve what God’s will is–his good, pleasing and perfect will.

Romans 12:1-2

Roy Dockum

Roy is excited to teach at CCS. He has a B.A. in Economics from Wheaton College, Wheaton IL, and an MBA from Oklahoma Christian University in Edmond.

Roy is married to his wife Mary Beth, son, Kent, daughter Beth, and 6 grandchildren with whom he loves to spend time. In his spare time, he and his wife love to travel. Roy has been fortunate to have been able to travel to over 60 different countries.

“Do not be conformed to this world, but be transformed by the renewal of your mind, that by testing you may discern what is the will of God, what is good and acceptable and perfect.”

Romans 12:2

Mr. Harris joined the CCS staff in 2018.

Mr. Harris has taught in several places throughout his 20+ years as an educator, including stops at Putnam City North (his alma mater), Edmond Memorial, Plainview (Ardmore, OK), Cashion, and Pottsboro, TX. At each place, Mr. Harris built solid life-long relationships with students and players; and continues to stay in touch with many of them.

A lifelong history teacher, Mr. Harris has taught US History, World History, Oklahoma History, US Government, Ancient World History, and World Studies. He is Advanced Placement Certified through College Board and has successfully taught AP United States History where several of his students received a “5” on the exam.

“Coach” Harris spent as much of his educational career on the athletic field as he has in the classroom. His first love is basketball, where he was the head coach at Cashion (1998-2003), Pottsboro, TX (2003-2005), Plainview (2005-2008), and Putnam City North (2008-2015). He also has served as assistant basketball coach at Putnam City North (1993-1998) and Edmond Memorial (2015-2017). Other sports Mr. Harris has coached include football, baseball, softball, boys and girls golf, boys tennis, and track.

His life is completed by his faith and his family. Janet, his wife, has been by his side for over 30 years and they have two grown children, Taylor and Blake.

A strong advocate for education, Mr. Harris believes he is fulfilling the call to ministry as a teacher by serving, edifying, and building up the body of Christ. He is passionate and focused on preparing students for the world we live in and specifically empowering students to succeed once they have graduated.

Coach Keathly feels God has called him to a ministry in the classroom as well as the football field. Early in his career a young student shared Luke 12:48 with him, to whom much is given, much is required, and he has reminded himself of these words daily.

But the one who does not know and does things deserving punishment will be beaten with few blows. From everyone who has been given much, much will be demanded; and from the one who has been entrusted with much, much more will be asked.

Luke 12:48

Ultimately, he sees his role of teaching encompassing all of life and not just mathematics.

Matthew foremost enjoys spending time with friends over a great cup of tea or coffee.

Not that I have already obtained this or am already perfect, but I press on to make it my own, because Christ Jesus has made me His own. Brothers, I do not consider that I have made it my own. But one thing I do: forgetting what lies behind and straining forward to what lies ahead, I press on toward the goal for the prize of the upward call of God in Christ Jesus.

Alexander Lau

Department Chair

Alexander Lau joined CCS in 2017. A native of Edmond, Alexander attended the Oklahoma School of Science and Mathematics for high school. He graduated summa cum laude with a Bachelor’s of Science in Zoology from the University of Oklahoma, and he was inducted into Phi Beta Kappa National Honor Society. During his years studying at the University of Oklahoma College of Medicine, Alexander discovered his true passion for instilling his love of science to others. He taught for 13 years at Classen School of Advanced Studies in Oklahoma City, and as Science Department Chair, he taught Advanced Placement Biology, International Baccalaureate Biology I and II, as well as Anatomy & Physiology, Physics, and Zoology.

Alexander enjoys ice hockey, and in his spare time his hockey team plays weekly and in out of state tournaments. Alexander was truly blessed to meet his very best friend–a stray Labrador puppy who followed him everywhere throughout the halls of school. That moment changed both of their lives. Years later, “Shadow” still acts like an excited puppy chasing tennis balls and Frisbees, and after rescuing Alexander, Shadow keeps him out of too much mischief during their daily, epic adventures.

Ask, and it shall be given you; seek, and ye shall find; knock, and it shall be opened unto you.

For the things that are seen are transient, but the things that are unseen are eternal.

Nathaniel Estrada


Nathaniel grew up in a Spanish speaking household with English being his second language. After graduating from U.S. Grant High School in 2002, he moved to Guadalajara, Mexico to take a discipleship training course and serve as a missionary through Youth with a Mission and the University of the Nations. Upon returning, he obtained his B.S. in Behavioral Science and Bible/Theology from Mid-America Christian University. He began teaching Spanish at Crossings in 2009.

Mr. Estrada believes a Christian education is an awesome opportunity for a child to develop a strong relationship with God early in life, so that, “When they are old they will not depart from it.” Not only can students have a relationship with God, but they can also have teachers and fellow believers all around to encourage them and guide them in the way they should go. When asked “Why do you want to teach in a Christian school?” He said, “In a Christian school, the ability to teach a child to strive for knowledge and excellence in this life as a Christian is very important to me… hopefully, I can impart to them what I know and broaden their minds in learning another language that can help them be a great success.”

The Estrada family includes his wife since 2007, Hope, their two children Ezekiel (2013) and Elicia (2015), and a miniature dachshund, Lolita. When not working, Nathaniel enjoys working with the youth at his home church where he is a deacon and plays the drums in the worship band. He also enjoys playing all sports especially golf and indoor soccer on the weekends.

Brothers and sisters, I do not consider myself yet to have taken hold of it. But one thing I do: Forgetting what is behind and straining toward what is ahead, I press on toward the goal to win the prize for which God has called me heavenward in Christ Jesus.

With God all things are possible and the transformations that we go through when we accept him are more beautiful than anything we can imagine. Ultimately, his students will learn how to tie together their experiences in music, life and as a Christian and apply them to their own lives.

She loves spending time with her family, whether playing board games, cooking feasts, obeying her nephews dictatorial commands, or going antique shopping with the girls.

Before coming to CCS, he had a twelve year career in Information Technology at companies such as the Daily Oklahoman, Dobson Communications and Sonic, following a four year career debating at Putnam City and in college.

Mr. Savill believes in helping to equip Christian students with the logical framework and persuasion skills needed to defend their faith against the myriad of intellectual attacks they will receive in college and beyond. By combining dialectic techniques with practice debates and learning about intellectual systems and Biblical examples, the student should calmly and persuasively argue that Christianity makes more sense than any other philosophy or structure.

The Savill family includes daughter, Olivia, French bulldog Blackberry and a slider turtle, Sacagawea. When not teaching, Dennis loves to read for fun and learning, watch movies and sports, travel and spend time with his favorite daughter.

And we know that God causes all things to work together for good to those who love God, to those who are called according to His purpose.

Therefore I tell you, do not worry about your life, what you will eat or drink; or about your body, what you will wear. Is not life more than food, and the body more than clothes? Look at the birds of the air; they do not sow or reap or store away in barns, and yet your heavenly Father feeds them. Are you not much more valuable than they?
