Sheila Dunleavy

About The Principal

I come to Most Holy Trinity School with 35 years of experience in public education as a teacher, administrator, and consultant.  As a mother of four grown-children, I feel that it is my greatest responsibility to ensure that your child is successful academically and spiritually.

My large Irish family and fourteen years of Catholic education have prepared me for this mission by shaping my core values and giving me the faith and strength to succeed. As a mother and a catechist, my convictions challenge me to instill in others the importance of education, faith, and the responsibility each of us has to make a difference.

Because I'm passionate about education, I have earned a Masters in Education and 30 additional hours in Educational Leadership. I am certified in both Elementary and Secondary Education, and I hold Detroit Archdiocese Catechist Certification.

When I'm not at Most Holy Trinity School you can find me hanging out with my kids who are also continuing their education. For fun we've discovered rafting, hiking, biking, and yoga.

If you have concerns, my door is always open.

Our Staff
The faculty at Most Holy Trinity School is outstanding and shows by their years of service dedication to this community and love for these children. Our students know that our teachers and staff will be there for them. Some of them have been here for more than thirty years! We feel the energy of those who are at the beginning of their career and continue to draw from those who are veterans and collectively they exchange strength from each other. The teachers are certified and the school has been accredited since 1994 by Michigan Association of Non Public Schools.

We have helped the neighborhood remain viable even through difficult years and are now experiencing a rebirth of housing and community- building in the area. You are always welcome to come for a homemade lunch or to visit us during the school day. We hope you will become an integral part of our life. We are confident you will feel proud to be associated with Most Holy Trinity School.
