Community Life


If there is a key to making the most of “the Mullen Experience,” it is to get involved! 
Over 90 percent of Mullen students participate in at least one extracurricular activity throughout the year. Find the activities that best suit you and discover what we mean when we say, “WE ARE MULLEN!” Due to the fluid nature of clubs, the below list is not exhaustive. At any time, students who wish to create and maintain a club should speak with Director of Student Life for approval and instruction.

  • Drum Line

    The Drum Line’s purpose is to support our school, primarily, but not limited to, through our sporting events. Drum Line is first and foremost a family where students give their best effort to grow as people and as musicians. It is an entity that is unlike anything else at Mullen. It will consist of hard work with great joy. We want students on the Drum Line to love the ensemble and show that love through their musicianship and effort during performances. The Drum Line is open to any student who wishes to give it a try. Most of the current members of the ensemble do not list percussion as their first instrument, but have enjoyed the pleasure of learning to play in a percussion ensemble. In everything that we learn and do, we work to: "Praise the Lord with our thunderous sound."
