The Spirit of Josef Award

The Spirit of Josef Award recognizes a current Mater Dei employee who exhibits the spirit of Josef by exemplifying his best traits either through quiet random acts of kindness, as a model of faith, a good listener, passion for Mater Dei, care for our planet and beloved school campus, or small quiet displays of compassion that often go unseen.

Who do you see walking Josef's path? We challenge you to not only look around for the "Josefs" among us in our faculty/staff community, but to also aspire to that type of quiet leadership and service as well.

Thank you to all who nominated an MD Employee for the 2024 Spirit of Josef Award. Congratulations to this year's winner - Anthony Vasquez '85.
