We are excited to announce the return of the After Prom at ThunderRidge!
The 2026 Prom will be on Friday, April 24th (more information to come in the spring), with After Prom taking place afterwards at Sporty Pickle. The kids will have plenty of fun and safe activities to do immediately following Prom. But we need community support to make this happen for our students! Our goal is to raise $7,000. You can make a donation by clicking here, or by scanning the QR code.
Please email Thomas Sullivan at thomas.sullivan@dcsdk12.org with questions.
