This summer, we’ve been hard at work planning for an exciting year ahead! Our goal is to raise $60,000 so we can give back to support students, staff, and programs for next year.

Every purchase and every event makes a difference. When you visit our outdoor concession stand, purchase Booster spirit wear, attend the craft show, participate in our dine-out events, or join us for Trivia Night, you’re helping us move closer to our goal. Thank you for your support!

We have a seat waiting for you!
