Welcome to St. Mary's School, Tracy MN


St. Mary’s School is a Christ-centered school where all students preschool through 6th grade enter to learn and exit to serve!  The value of developing the whole child is evident in the many programs and offerings at St. Mary’s. Through the integration of our academic classes, extracurricular activities, and spiritual growth opportunities, we invite our students to cultivate their God-given abilities. Our Catholic faith is at the heart of all that we do. The faculty and staff at St. Mary’s include individuals who are living out their vocations and whose unwavering commitment to both the students and teachings of Jesus Christ has made

St. Mary’s a very special place.

The combined contributions of our faculty and staff, students, and members of the community yield an environment of faithful witnesses to the vitality of the Church and the importance of education. We strive to seek the Truth in all that we do and attempt to make it our way of life. Our hope is that anyone who is present at St. Mary’s will see the Gospel witness of Jesus Christ in all our members as we work to create outstanding citizens of this world, but more importantly, citizens of Heaven.


It is my pleasure to introduce myself.  I am Mrs. Lisa Dieter, and I am the principal of St. Mary’s School as well as the instructor for physical education, social/emotional/mental health and music.  I received my Bachelor of Arts from the University of Minnesota – Morris and my Master of Science in Educational Leadership from Southwest Minnesota State University – Marshall.  I am a lifelong learner and have a very inquisitive mind.  I have 4 children and 8 grandchildren.  During the 2021-2022 school year, I was fortunate to have 6 of my grandchildren attend St. Mary’s School. Prior to my career at St. Mary’s, I worked in the public school system for 10 years.  When I joined St. Mary’s as an administrator in 2017, I experienced an overwhelming sense that this is where I truly belong.  I feel the love of God working within me and sincerely believe this is my calling to serve.  I extend my warmest welcome to you and encourage you to join our St. Mary’s School family!
