History
Sainte-Marie Mère de Dieu School came into existence in July 2022 as a result of the joint efforts of Mr. Ubertelli, a group of teachers, parents, and benefactors. Its purpose is to advance Catholic education with a traditional mindset in a rigorous, welcoming, and respectful environment, and to meet the needs of families seeking to educate their children through a thoughtful and conscientious approach. The school has assembled qualified and dedicated teachers who are recognized and experienced, each specialized in their respective fields of expertise. These teachers provide a classical and faithful education. The school has extensive premises in the Saint-François d'Assise church in the Hintonburg area of Ottawa.
MANAGEMENT and ADMINISTRATION
Francis P. Ubertelli, B.A., B.Ed., M.A., D.M.A.
Principal / CEO
Advanced French, History, Catholic Culture, Philosophy, Grades 9-12
Writer and composer by profession, Professor Ubertelli has taught for over twenty years in Ontario and Europe at the secondary and conservatory levels, and has significant experience teaching music, French, history, and philosophy. His studies and expertise include a Master’s degree in Music (Accademia Nazionale di Santa Cecilia, 1996), a Bachelor of Education (Laurentian University, 2009), and a Doctorate in Philosophy of Music (University of Toronto, 2020). A published author, he founded Sainte-Marie School in 2022, partly for his three children. He continues to write and compose alongside managing the school and teaching. For Professor Ubertelli, reason must necessarily be illuminated by faith—a faith informed by history.

A graduate in Social Work Technology from La Cité College, Mrs. Pion worked for several years in security, then as an administrative assistant for a provincial member of parliament until her first child. A stay-at-home mother, she joined the Sainte-Marie School team in 2025 with joy and enthusiasm.

He is a long-time catechist for the Catholic RCIA (Rite of Christian Initiation) where he lectures on Catholic apologetics in a scientific context as opposed to deceptive environmental “scientism.” For Professor Knight, faith and reason are intimately linked to the true spirit of discipleship.
