Our Faculty

Inspiring excellence - educating mind, body, and soul - a classical education in the Catholic tradition.


Divine Mercy Academy currently has four full-time faculty and one part-time faculty, and numerous volunteer educators. Our teachers work diligently every day to bring to reality the vision of Divine Mercy Academy as an institution of excellence in academics, prayer, faithfulness to Catholic teaching, and development of young men and women as heroic disciples of Christ’s Teachings. All DMA faculty have signed an oath to the Magisterium of the Roman Catholic Church.

Academy students experience their Catholic faith in a natural and holistic way because it permeates the curriculum, the classroom activities, and the teachers’ professional philosophy. Divine Mercy Academy teachers understand the importance of character formation and work in conjunction with parents to help each child develop virtues and a well-formed conscience.

Divine Mercy Academy teachers are not only excellent educators, but also individuals of faith. As a result, classrooms embody an uplifting Catholic culture. Our Faculty understand the importance of character formation and work in conjunction with parents to help each child develop virtues and a well-formed conscience. The staff of Divine Mercy Academy is committed to helping each student become capable of defending Truth in all aspects of personal and professional life. Our faculty accomplish this by teaching students the art of learning. We are are very blessed to have them join us in our mission.


  • After teaching first grade for 3 years in Polson, MT, I decided to move back to the Gallatin Valley to be closer to family. By the grace of God, DMA began that fall and I taught K-2nd grade. I have been blessed to continue teaching grades K-1st since that time. I am thrilled to be working with young children who are so eager to gain knowledge and grow in their faith. What a gift it is to be in a vibrant Catholic environment!

  • After teaching composition for 30 years at Montana State University, I am happy to teach in a Catholic setting, where the truths of our Faith flow naturally through all course work. Divine Mercy Academy’s classical curriculum fills the void I long perceived in public school education. Students at DMA learn to think clearly about all of reality. It is a pleasure to be a part of that instruction. My husband Bill and I have lived in the Gallatin Valley since 1977. Our daughter Ashley and her husband Dave Casto have been instrumental in the development of Divine Mercy Academy.
