A special sendoff for the Class of 2030! 🎉

Yesterday, our eighth graders were celebrated with a clap-out as faculty, staff, parents and classmates lined the halls to cheer them on as they left campus for the final time as middle school students.

We’re excited to celebrate this milestone with them and can’t wait to welcome them back in the fall as high school students. Congratulations, Class of 2030! 🧡💙

At our final assembly of the school year, we celebrated students as they prepare to step into their next grade and the next chapter of their EC journey. One of the assembly's most meaningful traditions took place as seniors handed roses to juniors, symbolizing the passing of leadership and responsibility to the Class of 2027 as they become EC's next senior class. As each class moved to its new seating section in the gym, eighth graders took their place among the high school students, marking the beginning of their next chapter at Eastside Catholic.

We also recognized several incredible accomplishments, including the Girls Lacrosse team winning the State Championship, our Boys and Girls Tennis teams for earning WIAA 3A Academic State Champion honors, and Owen and Aidan C. for capturing the State Doubles Championship.

As the school year comes to a close, we're grateful for the hard work, sportsmanship, leadership and service our students have shown in the classroom, in competition and throughout our community.

✨ Congratulations to our newest National Honor Society inductees!

This week, we celebrated 72 students inducted into the National Honor Society, in recognition of their scholarship, service, leadership and character. The ceremony also marked a special transition as this year’s NHS board passed the torch to next year’s student leaders.

Thank you to the outgoing NHS officers for their leadership and service. We look forward to seeing what the incoming board accomplishes in the year ahead.
