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.Ed., D.M.A.
Principal / CEO
Philosophy and Culture, Advanced French
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.

Liturgical Calendar
Wednesday, April 15 - FeriaEpistle
First Epistle of Saint John 5,4-10.5,4For whatsoever is born of God overcometh the world. And this is the victory which overcameth the world: Our faith.
5,5Who is he that overcometh the world, but he that believeth that Jesus is the Son of God?
5,6This is he that came by water and blood, Jesus Christ: not by water only but by water and blood. And it is the Spirit which testifieth that Christ is the truth.
5,7And there are Three who give testimony in heaven, the Father, the Word, and the Holy Ghost. And these three are one.
5,8And there are three that give testimony on earth: the spirit, and the water and the blood. And these three are one.
5,9If we receive the testimony of men, the testimony of God is greater. For this is the testimony of God, which is greater, because he hath testified of his Son.
5,10He that believeth in the Son of God hath the testimony of God in himself. He that believeth not the Son maketh him a liar: because he believeth not in the testimony which God hath testified of his Son.
Gospel
Holy Gospel according to Saint John 20,19-31.20,19Now when it was late the same day, the first of the week, and the doors were shut, where the disciples were gathered together, for fear of the Jews, Jesus came and stood in the midst and said to them: Peace be to you.
20,20And when he had said this, he shewed them his hands and his side. The disciples therefore were glad, when they saw the Lord.
20,21He said therefore to them again: Peace be to you. As the Father hath sent me, I also send you.
20,22When he had said this, he breathed on them; and he said to them: Receive ye the Holy Ghost.
20,23Whose sins you shall forgive, they are forgiven them: and whose sins you shall retain, they are retained.
20,24Now Thomas, one of the twelve, who is called Didymus, was not with them when Jesus came.
20,25The other disciples therefore said to him: We have seen the Lord. But he said to them: Except I shall see in his hands the print of the nails and put my finger into the place of the nails and put my hand into his side, I will not believe.
20,26And after eight days, again his disciples were within, and Thomas with them. Jesus cometh, the doors being shut, and stood in the midst and said: Peace be to you.
20,27Then he said to Thomas: Put in thy finger hither and see my hands. And bring hither the hand and put it into my side. And be not faithless, but believing.
20,28Thomas answered and said to him: My Lord and my God.
20,29Jesus saith to him: Because thou hast seen me, Thomas, thou hast believed: blessed are they that have not seen and have believed.
20,30Many other signs also did Jesus in the sight of his disciples, which are not written in this book.
20,31But these are written, that you may believe that Jesus is the Christ, the Son of God: and that believing, you may have life in his name.
