This historically is a Lock-in style party every year for all Hendrickson High School Graduating Seniors, featuring a safe, drug and alcohol free, event with entertainment, games, food, and hopefully fabulous prizes / supplies for their future journey.
This event is organized by anyone interested in supporting our Seniors. Each year community members, especially the voices of our Seniors, come together to plan this event. We call it: Senior Celebration Committee. Come to our meetings every 2 weeks in the Hendrickson Library or Cafeteria. It is never too late. Encourage our senior students and their biggest fans to attend meetings. We brainstorm together, contribute to planning the fundraising, volunteering and creating the events. GroupMe is how we are sharing communication. SignUp Genius for volunteer scheduling.
Who sponsors and pays for this event?
This is a 100% community funded event. There are donations of time, materials, prizes and money. Traditionally the community comes together to run nonprofit fundraisers and events to raise about $35,000 throughout the year with the ultimate goal of funding the Senior Celebration lock-in.

Celebrating our 2025 Hendrickson High School’s Seniors
May 27th-28th from 11:30pm-5am
Location: Spare Time
Hendrickson Seniors gather after graduation with their classmates. Senior Celebration is a free, fun, inclusive, safe, drug and alcohol-free event planned for the sole purpose of celebrating our graduating seniors on their very important milestone in life! All graduating seniors are highly encouraged to attend!
In addition, we’re hoping to have prizes. Items such as tv’s, laptops, dorm room essentials, gift cards, ear buds and headphones, speakers, travel essentials and lots more! (Disclaimer: While our intention is to provide prizes for the seniors, as of now we have not raised the funds for them, our priority is paying for the venue for the event. Should we raise enough to cover the venue, all remaining funds will go to prizes.)
