What do you love most about AACS?
Jesus says that how we love one another will let others know we are His disciples (John 13:35). AACS offers an environment that loves the whole child through spiritual formation, academic rigor, and athletics, all in Christian community. The staff actively partner with my wife Jami and me to make sure our children know and love Jesus, love others, and equip them to learn what God has called them to do in advancing His kingdom.
Why do you serve on the Board?
I’m passionate about the school’s mission to raise up children that know how to walk with Jesus as leaders and disciple-makers in today’s society. I’m honored and excited to guard and champion this mission as I believe that AACS will continue to grow and increase its impact for God’s kingdom purposes.
Why should families give AACS a hard look for their children?
AACS will uniquely partner with you to instill God’s truth in your children and help them to live an abundant life, with purpose, and on mission.
What is your favorite passage from the Bible?
“The Lord passed before him and proclaimed, ‘The Lord, the Lord, a God merciful and gracious, slow to anger, and abounding in steadfast love and faithfulness, keeping steadfast love for thousands, forgiving iniquity and transgression and sin, but who will by no means clear the guilty, visiting the iniquity of the fathers on the children and the children’s children, to the third and the fourth generation.’” – Exodus 34:6-7

What makes AACS so special to you and your family?
AACS is not just a school. AACS is our family, it is our home. When we first came from Germany and searched for a Christian school, all the ones in the area were declining us due to our children barely speaking English. Only AACS invited us. When we first stepped into AACS we felt the deep faith and love. The teachers and the AACS families helped all our children and us coming from a different country. We have such a close bond to all the teachers and they all have gotten to know our children so well over the years.
Why do you serve on the Board?
AACS has given our 3 teenagers a strong Christ centered foundation, which is so important when they go into high school and college. The experience I have gained from 3 teenagers, the differences in public and Christian high school, and the outlook to college is something I like to bring into the board as AACS adds a high school.
Why should families give AACS a hard look for their children?
Excellent academics which prepares our children well. All teachers and staff have and share their deep love with Jesus Christ. All our 5 children went through AACS and 2 still are. Having experienced how wonderful AACS and how it shaped our children, is the best testimony I can give.
What is your favorite passage from the Bible?
“I can do all things through him who strengthens me.” -Philippians 4:13

Rose and I were part of the group that founded AACS, and two of our children attended during the early years before our family moved overseas. We have remained long-term supporters of the school and have watched with awe and gratitude as AACS has continued to grow and flourish. I love seeing how God has blessed AACS and the lasting impact it has had on students and families throughout the community.

AACS has a mission to teach the whole child and prepare students for service in God’s kingdom. The school is blessed with outstanding teachers and staff who are committed to academic excellence, the development of lifelong learning, and the building of strong interpersonal skills—all while nurturing a personal commitment to Christ as Lord and Savior. As a parent, AACS is exactly the kind of partner I would want in equipping my children to live lives of faithful service in God’s kingdom.

What do you love most about AACS?
There are so many things that I love about Ann Arbor Christian School. The community is probably what I love the most. From day one of our family joining the school we have felt welcomed. The transition for both of our children was as seamless as we could have ever asked for. As a parent, knowing that our children are loved by every person that they come into contact with at school is priceless. Not only are they loved; they are challenged, cared for, prayed for daily, and pointed to Jesus in all things.
Why do you serve on the Board?
AACS means so much to our family and has had such a positive impact in our lives. I would love to see that impact reach other families throughout our community. I believe in the school’s history, mission and vision and I want to help to continue to grow His school in the city of Ann Arbor. We are in a season of growth at AACS – which is very exciting! I feel that by contributing and providing input at the Board level, I can continue to give back to the school that has given our family so much.
Why should families give AACS a hard look for their children?
AACS looks at every child in their own unique way and with the gifts that God has created in them. The staff and teachers all work together with great intention to develop and grow each student. Not only do they focus on academics, but they focus on the social, spiritual and emotional components of each child. AACS has created a community where students feel safe, loved, cared for, and challenged. It is within this community that students find the freedom to truly grow and thrive to become disciples of Christ.

What makes AACS so special to you and your family?
For the past 12 years, this school has been much more than a place where our children have received an education—it has been an important part of our family’s story. We are deeply grateful for the staff, who have invested in our children personally, and for the community, where we have built meaningful friendships and shared in the joys and challenges of raising our children together. Most importantly, we value the school’s commitment to Christian principles, which reinforces the faith, character, and values we strive to instill at home. We are equally thankful for the strength of the academics, which has challenged our children to work hard, think critically, and pursue excellence. After 12 years, we have seen firsthand how this school has not only educated our children, but helped shape their character, strengthen their faith, and prepare them for the people we hope they will become.
Why do you serve on the Board?
I serve on the Board because I believe deeply in the mission of our school and want to help steward the community that has invested so much in our family over the past 12 years. I want to use my experience, leadership, and perspective to help ensure the school remains strong and continues to provide an excellent Christian education for future generations. Serving is also a way for me to give back to a community that has played such an important role in shaping our children and supporting our family. Most importantly, I want to help preserve what makes this school special while helping it thoughtfully navigate the opportunities and challenges ahead.
Why should families give AACS a hard look for their children?
Families should give AACS a hard look because it offers a rare combination of academic excellence, strong Christian principles, and a genuine community that cares deeply about its students. AACS partners with parents to provide an education that prepares students not only for college and careers, but for lives of purpose, integrity, and service. It is a place where students are known, challenged, supported, and encouraged to pursue excellence.

The staff is quick to recognize and respond to individual strengths and challenges, while upholding a standard of academic excellence. What amazes me most is their commitment to shaping not only skills, but also the character and habits that make learning a lifelong pursuit—always rooted in the purpose God has for each child. At AACS, the staff doesn’t just teach—they nurture and guide children in the way of Christ.
