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.

--Matthew 6:19-21

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

Traci Kreger

Traci joined CCS in 2011. She has a B.S. in Secondary Education with an emphasis in English from Oklahoma State University as well as a M.S. in Applied Behavioral Studies with an emphasis in Gifted Education from Oklahoma State University. Before joining the CCS staff, she designed and implemented Piedmont Public Schools’ K-12 Gifted and Talented Program.

Mrs. Kreger loves to share her passion for English and literature. Her desire is to help every student foster a lifelong love for reading and learning to communicate well.

The Kreger family includes husband Joe, daughter Caroline and son Landon. Their family isn’t complete without their two Corgis, Maggie and Winston. When not working, Traci loves to travel, read, attend concerts, try new restaurants and root for her beloved OSU Cowboys.

Finally, whatever is true, whatever is noble, whatever is right, whatever is pure, whatever is lovely, whatever is admirable–if anything is excellent or praiseworthy–think about such things.
--Philippians 4:8


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 simple 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 audiobooks. Most of all, he enjoys spending time with his wife Melissa and daughter Ruth.

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 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.

Jonathan Keathly

Coach Jonathan Keathly joined the Crossings staff in 2017 and has since worked as a social studies teacher as well as the head football coach.

He has always had a passion working with young people and sharing God’s work in the world through history and current events.

Coach’s favorite memory as a teacher was having a meaningful discussion with a student about the verse written on her binder, Luke 12:48: “to whom much is given, much is required.” That discussion shaped his perspective of being accountable as a teacher and coach and the student says to this day she also saw her faith differently after that discussion.

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

Prior to Crossings, he was a Conversational English teacher in East Asia for two years and he also taught as a Lecturer in both the Mathematics and Statistics Departments at OSU.

Mr. Henneke views teaching as a balance of encouragement and instruction especially when tackling the subject of mathematics. He desires to incorporate a wide-range of examples and explanations into his teaching to be more effective in reaching his students. 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. He desires to continually learn new things about our world and God through reading, traveling, studying, and discussing. He also enjoys disc golf! He has also been blessed to travel extensively through Europe and Asia and desires to further his travels in the future.

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.
--Philippians 3:12-14

Mrs. Klossner loves teaching math! She understands that not every student feels the same way about math as she does, but loves the opportunity to change their perspective.

Katie and her husband Josh have been married since 2012 and have one son, Everett. When not working, Katie enjoys cooking, drinking LOTS of coffee, and spending time with her family.

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 believes that our study and understanding of science allows us to pursue a further understanding of God’s universe and ourselves. A personal goal of his as a science educator is to excite students to ask insightful questions, think critically, and love learning. While there may be many things we never fully understand, he looks forward to encouraging students to strive in their pursuit of knowledge.

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.
--Matthew 7:7

Holly Hixson

Dr. Holly Hixson joined CCS in 2020. She has a B. S. in Chemistry from Oklahoma State University and a Ph.D. in Chemistry from Kansas State University. Before CCS, she taught at Cairn University in Langhorne, PA, for two years. Prior to returning to the United States, Dr. Hixson served with her family in Kigali, Rwanda, East Africa, at Kigali International Community School for 11 years, where she taught science through the lens of a biblical worldview. Dr. Hixson taught at Oklahoma Christian University prior to her mission in Africa.

Dr. Hixson strives to show the connections between science and her personal faith in God. Her desire is to illustrate how science actually bolsters her faith in our Creator instead of contradicts it, as is a widely held view in many institutions and churches today. Dr. Hixson believes that new discoveries in science serve to reinforce belief in our Creator and to prove His existence and omnipotence. Further, that knowledge of these things allow opportunities to share the truths of God with others in ways that are unique to scientific disciplines. Dr. Hixson works to train students to critically analyze the information presented them, instead of accepting information at face value.

Dr. Hixson married her husband Bryan in 1991. She has two godly, intelligent, and beautiful daughters, Alexis and Grace. Dr. Hixson loves to learn new things, especially things related to scientific evidence for faith. She also loves to travel to new places, to meet people from other cultures, to sing, and to sew whenever she gets the chance.

Dr. Hixson loves to pray through Psalms 23, 27, 46, and 91, as they were instrumental in the ministry in which she participated in Rwanda.

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.
--Philippians 3:13-14

Dennis Savill, M.A.


Joining Crossings in 2012, Dennis has a B.S. in Computer Science from Oklahoma City University and a M.A. in History from the University of Central Oklahoma. 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.
