Alma Mater

Fling out that vibrant spirit of Mission High.

Our loyalty to you will brighten the sky.

We pledge our full alliance,

Placing reliance, shouting defiance, ALMA MATER.

Our hearts are filled with courage, keeping us true,

Spreading our fame and fair name, we dare and do,

And homeward turn with burning love and zeal


Dominican Blessing

May God Creator bless us.

May God Redeemer heal us.

And may God the Holy Spirit fill us with light!
