Her desire to join the Capstone community began by learning about the classical model of education. She is drawn to its intentional pursuit of what is Good, True, and Beautiful in all content areas and its goal of forming critical thinkers and articulate communicators. She feels it is a great gift to participate in a community striving to draw students closer to Jesus through classical education.

Roxanne and her husband, Brian, are members of Sts. Anne & Joachim church. They have been married for almost 30 years and have the privilege of raising six children from 12 to 26 years of age. Their family enjoys playing board and card games together. In her spare time, Roxanne enjoys reading, scrapbooking and baking.

Greta Railing holds a bachelor’s degree in English and Writing from Liberty University. After serving as a classroom aide during the 2024–2025 school year, she quickly came to love Capstone’s joyful, Christ-honoring community and began her teaching career with us the following year.

Greta is excited to be part of a school that emphasizes character formation and a biblical worldview. Her goal is to model and teach strong academic habits and a love for learning.

Kendra Kudrna holds a bachelor’s degree in Elementary Education from the University of North Dakota. This will be Mrs. Kudrna's 7th year of teaching, and her 4th year as a 4th grade teacher! 

Mrs. Kudrna feels deeply encouraged by the intentional way the classical model cultivates lifelong learners and ignites curiosity in all that is true and beautiful.  Kendra strives to cultivate peace, humility, and goodness in her students so that they may carry those virtues with them outside of the classroom. "There are so many things that just feel right about Capstone, but most importantly that God is at the center of all we desire to do and are able to do."

Kendra lives in West Fargo with her husband Mitch and their three boys. They love to hike, ski, and travel to the mountains to explore God’s beautiful creation together. In her free time, Kendra loves to read, organize, paint, and play sports with her family. She looks forward to building relationships and growing in her faith alongside colleagues, students, and their families.

Mrs. Georgia Thompson holds degrees in Human Development and Family Science and Elementary Education from North Dakota State University and Valley City State University, graduating in May 2026. Having attended a Christian elementary school herself, she is grateful for the strong foundation of faith it provided and is excited to bring that same Christ-centered perspective to her classroom.

Mrs. Thompson is thrilled to begin her teaching career at Capstone and to become part of a community committed to educating the whole child in truth, goodness, and beauty.

Outside the classroom, Mrs. Thompson enjoys crafting, baking, traveling, and spending time with her husband and their two sons. Her family attends St. Joseph’s Catholic Church in Moorhead.

Molly Wobbema holds bachelor’s degrees in Elementary Education from Valley City State University and Child Development and Family Science from NDSU.

She served as a tutor and director of a classical homeschool community, where she helped others classically educate their own children, for five years. Mrs. Wobbema loves helping 5th graders cultivate wisdom and virtue as they begin to desire more dialectic conversations.

Robert Brandau was born and raised in Colorado. He earned his B.A. in History with a minor in Classical Education at Hillsdale College. He and his wife, Emelie, are excited to join the Capstone faculty in the fall.

"Capstone won us over to its mission and vision because of how it balances the classical and Christian elements of a good education, wherein students are invited into the enchanting world of learning about the source of the three Transcendentals—God Himself," says Mr. Brandau. He continues, "If that was not enough, the school community revealed its heart for hospitality and the noble commitment of spurring on one another to love and good works. We are thrilled to move to Fargo and extend the same hospitality to our new neighbors."

Mr. and Mrs. Brandau have been married since May of 2024. They enjoy quality time with each other in its various forms: daily devotions, reading their favorite books to each other, camping, hiking, and visiting museums. In his free time, Robert enjoys rugby, volleyball, and Brazilian Jiu Jitsu. Even more often than athletic pursuits, he finds himself delving into a work of theology, history, or literature, and subsequently trying to share what he learns with others. He and his wife are new to Fargo, but they are considering membership at a church in the Lutheran Church-Missouri Synod.

Kaylie comes to Capstone after teaching for 12 years in Enderlin and Casselton. She earned her B.A. in English Education from NDSU and her M.S. in Education with an emphasis in English from Valley City State. She is a Colson Fellow and is passionate about seeing life through the lens of Christ. She is excited to be able to educate students in a classical model that also shows the centrality of Jesus Christ.

For Kaylie, good teaching is modeled after the greatest teacher, Jesus himself. She believes that through his words, she and her students learn what it is to truly become wise and virtuous. She strives to be a living example of Christ in fulfillment of the Great Commission. Her prayer for her students is that they learn and grow and become smarter than her.

She and her family attend West Prairie Free Lutheran Church in rural Kindred. She and her husband, Dustin, have three beautiful children and live on a farm in southeast North Dakota.

When Kaylie is not teaching, she loves to travel, read, and craft. You will often find her on her front porch reading and taking in God's beauty.
