Meet Our Interim President & Assistant Principal

Dear MSM Community,

We are pleased to announce and welcome two additional members to the administrative team at Mount St. Mary Catholic High School, Assistant Principal David Roberts and Interim President Tony Tyler.

David is returning to The Mount after two years as secondary principal at Oklahoma Christian Academy. He has previously served Mount St. Mary for over 15 years as an English teacher and later as the Dean of Curriculum and Instruction. As assistant principal, David will assist Mrs. Laura Cain in stewarding the school’s mission and values.

“David Roberts brings exactly the right combination of expertise and experience to the new administration at MSM. He shares our commitment to form well-educated disciples of Jesus and build meaningful relationships with students. I am thrilled that God called Mr. Roberts back to The Mount,” stated incoming principal Laura Cain.

Interim principal, Dr. Diane Floyd shared, “David Roberts return to The Mount is an incredible addition to our team. His alignment with our school’s mission and values is evident as he is deeply committed to a vision of education that prioritizes Christ as the root and apex of authentic learning.”

The Board of Trustees recently commissioned the creation of a school president position. The president will work closely with the Board, its executive committee and MSM’s administrative team to foster an environment of excellence in all operations, and add an additional layer of accountability for our leadership team. This position also will supervise the school’s business office, financial operations and external functions.

As our President Search Committee diligently works to fill this new role, we are pleased to welcome MSM alum Tony Tyler 1988, who will serve as interim president. Tony brings an extensive business background and will play a crucial role in creating long-term success for this position.

With a heart for The Mount and our Oklahoma City community, Tony brings a deep understanding of business and nonprofit board leadership, which will aid in the development of the new president role. During Tony’s time as interim president, he will be an active presence on campus and in the community to advance The Mount’s mission and core values. The Board knows Tony will passionately serve The Mount while creating, renewing and building relationships that are critical to our future.

“We are enthusiastic that Tony has agreed to serve The Mount,” said Board of Trustees Chair, Dan Carsey. “The Board unanimously supported Tony’s interim president appointment and trusts him to lead The Mount and ensure stability and momentum until the President search is complete.”

The Board of Trustees, The Sisters of Mercy and the Archdiocese of Oklahoma City have full confidence and support in the future of The Mount under our new principal, assistant principal and interim president. Please join us in welcoming them to their new roles.
