Kindergarten Teacher

Jill Hultink

Mrs. Hultink studied elementary education at Cornerstone College and has worked in a variety of educational and administrative settings aiding in preschool, developing a catechesis curriculum and program for school-age children, and managing the office of her family’s business. She also previously assisted with office responsibilities and was a classroom aide at Trinitas. We are pleased to have her as our kindergarten teacher. Mrs. Hultink is well-suited for this position and is a warm and welcoming presence for all who come to the school, including our youngest students.

1st/2nd Grade Teacher

Susan Mehari (B.A., Hillsdale College; M. Ed., Cornerstone University)

Both a National Merit Scholar and honors student at Hillsdale, Miss Mehari majored in history and minored in Spanish. Classically educated herself, she is a teacher who has both an excellent rapport with children and extensive knowledge of classical education. 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.

She helped launch a new Classical Conversations home school program in her area and served as Children’s Ministry Director, K-12, at her church in Pennsylvania. She has received ongoing training in classical philosophy and methodology and has a passion for classical education. With her 16 years of experience in education, Mrs. Bodine brings maturity, creativity, and energy to the classroom and the Trinitas community.

Bible/Greek/History/Logic and Headmaster

Peter Marth (B.A., Concordia College; M. Div., Concordia Theological Seminary)

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.


Mary Beth Roossien (B.A., Calvin University; M.A., Aquinas College)

Mrs. Roossien has taught in a variety of educational settings including the homeschool association. She is passionate about opening the world of art history to students, using the great masters to teach the students the elements of art. Mrs. Roossien also introduces the students to the great masterworks of art history as inspiration for their projects, having the students create art projects in the various styles of those masters. Mrs. Roossien has a master’s degree in education as well as certification in art education for K-8. Mrs. Roossien is not only experienced in the visual arts but also in music having been a band director for Lamont Christian, Allendale Christian, and Grace Homeschool Association and a General Music teacher for Lamont and Allendale Christian. We are delighted that she brings her wealth of experience to the fine arts program at Trinitas.


Maureen Richards (B.S., Central Michigan University; M.A., Aquinas College)

Mrs. Richards teaches 7th and 8th grade grammar and 5th through 8th grade literature and composition classes at Trinitas. She retired from the United States Army Reserve at the rank of lieutenant colonel after 24 years of service, the last seven as a history and leadership adjunct instructor for the Army’s Command and General Staff College. She spent four years teaching 11th grade English and 12th grade rhetoric at a Christian K-12 school where she developed a love for the classical and a passion for joining “The Great Conversation.” Although her master’s degree is in education and her bachelor’s degree is in English and Psychology, she believes that her real education did not begin until she started studying logic, rhetoric, history, and English through a biblical worldview and discovered God’s thumbprint in literature as man’s restless soul cries out for the rest that is only found in his Creator. Mrs. Richards brings to Trinitas a wealth of knowledge and experience and a tireless commitment to classical education and our students.

Kellie Roblin (B.S. and B.A., Grand Valley State University; M.A. University of Illinois; MFA, Queens University of Charlotte)

Mrs. Roblin has degrees in psychology, English, English literature, and non-fiction writing. Before joining the Trinitas faculty, she taught college composition and literature courses for twelve years. Always seeking ways to grow, she also coordinated a college writing center for five years and started a small business in which she helps people with writing projects outside the academic realm. She is trained in the Orton-Gillingham method for literacy ed and is a certified EFL teacher. Making connections with students and learning alongside them is her passion. She most enjoys moments in which students are willing to stretch their skills and try new techniques or achieve a new goal. Mrs. Roblin’s work has led her to a great appreciation for Classical education. The in-depth understanding it provides each subject works like a craftsman’s toolbox; each instrument is well-worn and familiar to students who by nature have compelling questions and are eager to learn effective means for finding true, good, and beautiful answers.


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

Mrs. Tellinghuisen teaches 5th through 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.

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.
