Looking to get involved at Mountainside? If you missed Club Fair at the beginning of the year, there are still plenty of opportunities to find a club that interests you!
Check out the Club Board in the band hallway, right next to the office when you walk into school, to explore the different clubs available. You can also learn more about clubs through our Virtual Club Fair Slideshow, Instagram Club Spotlights, and the Mountainside website under Activities & Clubs.
There are so many ways to get involved, meet new people, and find your community at Mountainside. Take a look and find a club that’s right for you!

Step into the spotlight at our Halloween Fashion Show during both lunches on the stage! Every participant will receive a treat just for showing off their outfit, and the top winner will take home a pack of Oreos. Please remember that masks or anything that hides your identity are not allowed, and no fake weapons or dangerous props can be brought to school. Bring your best fit and see you on stage, Mavs!
