Athletic Staff

Tom Bouma

Athletic Director

I have worked at Calvin since 1986. God has been in charge of my career path from the beginning. Out of college I fully intended to take a job offer in Tennessee when my future mother-in-law suggested I look into Calvin.  I was hired to teach 8th grade Language Arts, and I had my future brother-in-law in class my first year!  Along my teaching trail I have taught 7th and 8th grade Language Arts, American Literature A and B, College Writing, World Literature, English Literature and even Algebra B.  At the middle school I have coached basketball and track. At the high school I have coached JV baseball, JV football, and I was the varsity football coach for thirteen years. In 1992 I became the Athletic Director.

I attended South Christian High School and received a B.A. degree in Education and English from Calvin College. I earned my Masters degree in Secondary Administration from M.S.U. My beautiful wife, Mary,  teaches kindergarten at Grandville Christian. We have four incredible children and one son-in-law, and each one of them has had the opportunity to have a  fantastic Grandville Calvin Christian education.

I am also a licensed builder and my hobby has been building houses for our family to live in. Also I love to read, watch M.S.U. sports, and work in my yard.  One of my favorite passages deals with trusting God today and tomorrow. Matthew 6:19-34, especially the summation in verses 33 and 34.  “But seek first his kingdom and his righteousness, and all these things will be given to you as well. Therefore do not worry about tomorrow, for tomorrow will worry about itself. Each day has enough trouble of its own.”

Linda Eisma

Athletic Admin. Assist.

Some of the fastest, rewarding  hours in my week are spent at CCHS.   It is a joy to help prepare the schedule for the games, meets and matches our athletes compete in.  What a privilege it is to see Calvin Christian sports from this perspective!  We are truly blessed to have an Athletic Director who sets a solid foundation and vision for our school’s athletics, and dedicated, caring coaches who take this vision and teach and train our children every day.  We serve a great God who deserves our very best.  Each time our athletes put on a uniform with the name “Calvin Christian” on the front, they have the privilege of reflecting our school and the awesome God we serve.

I have an Associates Degree in Business from Grand Rapids Community College.  My previous experience came from many years working in the Chief of Police’s office in the City of Wyoming.  This is a very different environment to say the least!  My husband, Doug, and I have four children who attend Grandville Calvin Christian School.  

I have many Bible verses that are special to me; but in the context of my job, I would like to share Colossians 3:23-24.  “Whatever you do, work at it with all your heart, as working for the Lord, not for men, since you know that you will receive an inheritance from the Lord as a reward.  It is the Lord Christ you are serving.”

Pete Overvoorde

PE, Boys' & Girls' Varsity Bowling Coach

In 2006 I joined the CCHS staff and since then have had the privilege of talking to young students about the importance of physical health and wellness and how those things can directly and indirectly influence a person’s ability to serve the Lord. Not only do I do this through teaching, but I try to model this by living a lifestyle reflective of the physical gifts and abilities God has blessed me with. Prior to teaching at Calvin Christian, I taught both elementary and middle school health and physical education in other schools. I also was able to interact with diverse groups of kids while serving as Coordinator for Pre-College Programs at Calvin College. In addition to teaching, I currently serve as the boys and girls bowling coach, and have also held the post of the head boys track and field coach for a number of years.
I am a father of three amazing young children, who also share a love of fun and physical activity. Mountain biking and road biking are two of my favorite hobbies. To me, there is nothing like getting a great workout in while enjoying the wonderful landscape God has painted for us all to enjoy. Other than that, I love to live vicariously through my children by cheering for them at soccer, volleyball, and basketball games. A favorite saying of mine is, “Things turn out best for the people who make the best of the way things turn out”.

Dan Olthoff

Algebra, Geometry, Physics, Girls' Varsity Golf Head Coach

Although I was born in Grand Rapids, I grew up in California and Florida. I attended Calvin College where I received a degree in Engineering in 2000. While I was finishing that program I felt God strongly calling me into education, so after graduation I continued at Calvin where I got my secondary teaching endorsement with a major in Mathematics and a minor in Physics. I had the privilege of student teaching at Calvin Christian HS in the fall of 2001. After completeing this assignment I was offered a full time position, and have since taught Physics, Precalculus, FST, Statistics, Geometry, and have now started teaching Algebra as well. I have also received a Master’s Degree in Mathematics from Grand Valley State University.

During my time at Calvin I have also coached over 30 seasons in a variety of sports (golf, basketball, track, and bowling) and been a Young Life leader. I consider a wonderful privilege and responsibility to be member of this community at Calvin Christian HS.
I am a member of Fellowship CRC, enjoy gardening, cooking, bicycling, running, and swimming.

Karel Malefyt

Choir, Orchestra, Boys' Varsity Soccer Head Coach

I thoroughly enjoy the diversity in my work, sharing my passion for my Lord, music and competition, and the opportunities to build relationships with the families at Grandville Calvin Christian Schools.  I am blessed and thankful to have taught here since 2006. In addition to teaching high school choir and orchestra, I also teach middle school choir and orchestra and elementary school orchestra and coach the boys Varsity  and girls JV soccer team.

I am a graduate of Hudsonville and Unity Christian School, and a graduate of Calvin College with a degree in Vocal Music Education.  I am currently a member at LaGrave Ave CRC.

When not teaching, I enjoy my time outdoors golfing, fishing, camping, or sometimes just walking while gazing at God’s incredible creation.  My favorite passage is Psalm 100:  “Shout for joy to the Lord, all the earth.  Worship the Lord with gladness; come before him with joyful sounds.  Know that the Lord is God.  It is he who made us, and we are his; we are his people, the sheep of his pasture.  Enter his gates with thanksgiving, and his courts with praise; give thanks to him and praise his name.  For the Lord is good, and his love endures forever; his faithfulness continues through all generations.”

Kelli Boender

English, Global Studies, US History and World History, Softball Assistant Varsity Coach

After graduating from Calvin College in 2014 with a BA in secondary education (History and Socials Studies major and French minor), I taught one year at the West Michigan Aviation Academy in Grand Rapids.  

I believe Christian education is essential to raise up the next leaders of the Kingdom of God. I hope to teach my students discernment, compassion, and awareness of their neighbors. As a history teacher, themes of justice, the forward movement of history and the hope for the second coming teach so much about how each of us is to live our lives here in this world as preparation for heaven.

One verse that I love is Acts 20:24  – “However, I consider my life worth nothing to me; my only aim is to finish the race and complete the task the Lord Jesus has given me—the task of testifying to the good news of God’s grace.”

My husband, Joel, and I are both graduates of Calvin Christian High School.  I love to run road races, read books, watch the Tigers, visit the zoo, and being outside whether it is camping or sledding,

Krista Gray

Educational Support Specialist, Volleyball JV Head Coach

I am a graduate of Grand Rapids Christian High School and Calvin College.  I gradated from Calvin in December 2015 and received a degree in K-12 Special Education: Cognitive Impairment and K-8 Elementary Education.  After graduating I served as a long-term substitute at Calvin Christian High School and am incredibly grateful to now be serving here in a permanent position!

Teaching special education has always been something I have been interested in.  I grew up with five adopted uncles and aunts with varying cognitive, emotional, and physical impairments.  I have grown up with them and watched them grow into incredible, confident adults with great talent and faith in Christ.  As a teacher, I am so excited to watch my students’ confidence in themselves, their talents, and their faith grow during our time together!
My husband, Eric, and I met at Calvin College.  Outside of teaching I enjoy traveling, reading, running, playing sports, and spending time with family and friends.
