Miss Mehari is an invaluable member of the Trinitas community, as she brings a wealth of ideas, energy, and educational expertise to our school.  In the two years our students are in her classroom, Miss Mehari does a masterful job of transitioning them from kindergarten to the responsibilities of 3rd grade.

Before joining Trinitas for its inaugural year in 2006, Mr. Marth was senior pastor of St. Peter Lutheran Church in Hilbert, Wisconsin. In addition to his pastoral responsibilities, he taught 5th and 6th grade at St. Peter’s Lutheran school, where he designed and implemented a classically-based religion curriculum. Mr. Marth also taught Greek at Concordia College and courses in 7th and 8th grade at Zion Lutheran Academy, a classical school. A 2011 graduate of the St. Stephen’s Course in Orthodox Theology, he serves as a subdeacon in the Antiochian Orthodox Church. Mr. Marth brings to Trinitas a rare blend of administrative, pastoral, and academic experience in a classical setting. He has an excellent rapport with students, teachers, and parents alike. We are delighted to have a man of so many talents with us.


Liana Williams (B.A., Hillsdale College)

Liana Williams is a graduate of Hillsdale College where she studied English Literature and classical education and was involved in ballet, piano, and community leadership. Growing up in a homeschooled family of ten, Ms. Williams enjoyed assisting her mother in the education of her younger siblings. She continued to grow in her love of working with children through her time as a camp counselor, and her passion for education was increased by her education classes at Hillsdale. Ms. Williams believes it is the intentional focus on student character that sets the classical approach apart from other forms of education, and she hopes to pursue a Master’s degree in classical education in the future. We are glad to have Ms. Williams guide our 5th through 8th grade students in the reading of great works of literature and in the discipline and art of writing.


Rebecca Tellinghuisen (B.A., Augustana College; M.A., North American Baptist Seminary)

Mrs. Tellinghuisen teaches 5th-8th grade Latin. A lover of language study from her middle school years, she studied Greek and Latin while pursuing a master’s degree in Bible and theology with a focus on early church history and theology of baptism. She served as a classroom aide in our Latin classes for many years while her children were attending Trinitas as homeschool partners. In addition to part-time homeschooling, she held various church positions in the areas of early childhood, youth educational ministries, and worship leadership. A co-founder of the Reader’s Theater program at Trinitas, she looks forward to helping our students enhance their knowledge and love of Latin through skits and plays. She also serves the school as the Communications and Marketing Assistant. We are grateful for the combination of insight, creativity, and love of education that shines in all Mrs. Tellinghuisen does for Trinitas.

Although Mrs. Steenwyk has lived in West Michigan her whole life, she has been passionate about exploring the world and experiencing history through books and travel for as long as she can remember. Having worked as a children’s ministry curriculum writer, a theological editor, and an English composition and literature professor, her own educational and occupational history fits wonderfully with our goal of helping students learn to write and communicate well. She has also published children’s books on baptism and communion. Mrs. Steenwyk is drawn to classical education because it encourages discernment and invites students and teachers to join in meaningful, ongoing, and transformative conversations.
