Mrs. Lacey Oettel


My favorite aspect of my current role is watching the teachers and students grow in their love for their Savior.   I am amazed at what God is doing at CCA and how he continues to bless and grow the school over the last six years. It has been a joy to watch a dream and a desire of mine turn into a reality-only because of Jesus.

Mr. Colin Rueter

Dean of Students, Logic & Omnibus

My favorite part of CCA is growing in relationship with my fellow teachers and with students as we pursue Jesus. My favorite part of the day is our morning assembly and chapel when the entire school is together to fellowship, recite, and learn together. My favorite book is "Confessions" by Augustine of Hippo. An honest look at the Christian faith & the struggles of life in this world amidst the abounding grace of God.

Mrs. Theresa Hafstad


What I love most about CCA is that the class sizes are small. This makes it easier for teachers to really know their students and help them in areas they struggle and push them in areas they excel.  The favorite part of my day is first thing in the morning when the day is new and fresh and the anticipation of the amazing things that could happen today! I love books!!!  I don't want to hurt other books' feelings by choosing just one!

Mrs. Cathy Williamson

first & second Grades

Teaching at CCA affords teacher and curriculum accountability, encourages like mindedness among staff, and insures doctrinal safety. Did I mention that the class size encourages learning, joy, and a personal touch for students? And did I say we all laugh a lot? Teaching at CCA is the greatest gig of my many years. My favorite part of the day is Bible class, and every time I see an “ah-ha” moment in any subject. My favorite book-that’s a hard one. Being married to a pastor, and having taught for quite a number of years, I’d have to pick favorites from categories: Children’s Humor: “Hank the Cow dog” or “The Best Christmas Pageant Ever” Dialectic level motivation: “Carry on, Mr. Bowditch “ Theology: (After the Bible): “Delighting in the Trinity”

Mrs. Abby Vollmer

third & fourth grades

I love the students and staff of CCA. I especially like how we encourage each other to glorify God and enjoy Him forever! My favorite part of the day is when I get to work one on one with students or when students are collaborating with each other. I love to see students encourage and support one another. Two of my favorite books are "This Side of Paradise" by F. Scott Fitzgerald and "East of Eden" by John Steinbeck.

Mrs. Susan Rueter

5th & 6th GradeS

I LOVE the Classical model of education and watching students connect the dots between history, science, writing and tying it all back to God.  It is truly a gift to be at the same place as my sons and husband.  A ministry we are all involved in is such a blessing. History is a favorite part of my day.  I have too many books to name that are favorites: ministry book - "Adorned" by Nancy DeMoss Wolgemuth; "Parenting" by Paul David Tripp; "The Landing Place" by Clint Kelly; and bibliographies of missionaries.

Ms. Olivia Busch

UPPER SCHOOL Latin, writing & Rhetoric

It is very hard to choose just one thing I like about CCA, but I love the "light-bulb" moments in the classroom when students "get it" and want to explore more and ask more questions. I love being a lead learner. My favorite part of my day is standing in front of my Latin class and seeing the effects of training another generation of young minds to see the world through a language that shaped Western culture. My favorite book is "Emma" by Jane Austen. Emma Woodhouse is a witty, inquisitive, refreshingly-imperfect heroine, and I see much of myself in her.

Mrs. Melba Ratliff

Kindergarten Music, 3rd & 4th Grade Art

Students are interesting to interact with and younger students are great with their enthusiasm and spontaneity, hence I enjoy teaching. My favorite part of day is hearing the kindergarten  students sing  plus observing the artistic talents of 3rd and 4th graders. I have many favorite books. I read the Bible in Spanish  "Dios Habla Hoy"  and I just finished reading for the second time, a book entitled The Story of the Trapp Family Singers
