What is your favorite Bible verse?

 “Sanctify them in the truth; your word is truth.” John 17:17

When my wife Linda and I took a course on I Corinthians with Dr. Paul Ryrie, I asked him to sign my Bible at the conclusion of the course. He signed his name and wrote the reference John 17:17. That really stuck with me. I wanted to emulate that kind of statement he was making. I want to stand for truth and honor the Word of God.  

Why do you choose to serve at Dayton Christian School?

My wife and I came to know Christ on the same day — I was 25 and she was 22. We had both come from families that weren’t believers and so I came to see how important Christian education was to my life and to my own family’s. I felt a distinct call on my life to Christian education during a youth leader training course I attended at Cedarville University. I soon left my job and enrolled in Word of Life Bible Institute (even though I had advanced degrees at the time) to get the Biblical training I needed. I am at Dayton Christian because I believe so strongly in Christian education; it has been my life’s work. It is my vision that each student would discern their life’s calling and find true success in life — which is all about serving Christ and serving others. 

 What are your hobbies or interests?

I really enjoy sports, especially playing basketball and tennis. My wife and I like to garden and do landscaping together. And, of course, I love spending time with my grandchildren!

James Holliday, High School Principal (7-12)

 What is your favorite Bible verse?

“Count it all joy, my brothers, when you meet trials of various kinds, for you know that the testing of your faith produces steadfastness. And let steadfastness have it full effect, that you may be perfect and complete, lacking in nothing.” James 1:2-4

This has been my favorite verse since high school. I love Christ with my whole heart. I love his forgiveness and love. I also love to be a problem solver and look at trials as opportunities to grow and mature. James is relaying a message I try to live out on a daily basis. Through marriage, work, friendships, and leadership I look to lean on Christ in the easier and more difficult situations alike.

Why do you choose to serve at Dayton Christian School?

I came to Dayton Christian as a first grader. By the time I graduated, I was sold on Christian education — so much so that I went on to Huntington University, a Christian university. Once I got to college, I realized that when I made mistakes or found myself in trials, I had a genuine foundation in Christ. This foundation did not happen overnight. It came from daily experiences with the teachers who had loved me and taught me truth. I graduated from college with my education degree and came home only to apply to one school, Dayton Christian. From that day on, I have been dedicated to paying it forward, to loving my co-workers, students, and partnering families, and to growing spiritually and mentally. I love being here at DCS, and I find it a great privilege to be able to serve the Lord alongside so many gifted and talented individuals.

What are your hobbies or interests?

I am a very active athlete who loves to problem solve and learn. I coach the soccer team and enjoy being able to build relationships through athletics. I am also a sponge that loves to take in as much as possible from as many influential individuals as possible. My wife and I love to spend time together watching our shows, taking walks, and going on adventures. Our favorite thing to do is to parent our daughter, Tory, as she grows up. There is no greater joy than seeing her reach new milestones and having her keep us on our toes! 


Rich Garrett, Elementary School Principal (preK-6)

What is your favorite verse?

“So if there is any encouragement in Christ, any comfort from love, any participation in the Spirit, any affection and sympathy, complete my joy by being of the same mind, having the same love, being in full accord and of one mind. Do nothing from selfish ambition or conceit, but in humility count others more significant than yourselves. Let each of you look not only to his own interests, but also to the interests of others. Have this mind among yourselves, which is yours in Christ Jesus…” Philippians 2:1-5

My wife and I have considered this passage in Philippians as a favorite for many years. Unity comes from having the same mind in Christ and humbly looking to each other, not ourselves. We need to have the mind of Christ as we serve those around us.

Why do you choose to serve at Dayton Christian School?

I am starting my 36th year at DCS. God called me here in 1982 to be used of Him in the generations to come. To have the privilege to use His Word daily and encourage children and parents in their walk with the Lord is awesome. I have the opportunity to help teachers become the best role models they can be. Also, I have the joy of working with parents to raise their children to become godly young men and women. Working at Dayton Christian allows me to be a servant and instrument of God for the building of His kingdom. Why would I not want to work here? It is a honor and a blast!

What are your hobbies or Interests?

My wife and I enjoy gardening. We raise all kinds of vegetables in our backyard. Working in the yard is also an interest of mine. I enjoy working with wood and doing projects around the house. Our nine grandchildren are more than a hobby or interest — they are a big investment for us, and we enjoy it. Reading historical books and books that will develop my walk with the Lord is a great interest I have. My wife and I enjoy going for hikes throughout the Metro Parks and in our neighborhood.
