Rain will NOT stop us. What. A. Day.
It wouldn’t have been possible without Mrs. Lippe, Jenn, Erica, Kristin, and Joni. Thank you for pivoting and absolutely nailing it.
Until August, SJ23…✌🏻
And just like that… another school year comes to a close.
As summer begins, we hope our students and families take time to slow down, rest, recharge, and enjoy every moment together. Sleep in a little, soak up the sunshine, make memories, and enjoy all the simple joys this season ...brings. Thank you for sharing your year with us — for the laughter, learning, growth, friendships, and countless moments that made this year so special. We are incredibly grateful for our SJ23 community.
Have a safe, relaxing, and joy-filled summer break. We can’t wait to see you again soon! ☀
A Final Farewell…🎉
You’re always welcome…please come visit! ♥️
Field Day is one of our students’ favorite days of the year…for obvious reasons! ☀️💦
A huge thank you to the Port Washington Fire Department for helping make this year’s Field Day extra spectacular.
What a fun way to celebrate an incredible year and close out the ...2025–2026 school year. We are so grateful for the memories made and the community that helps make days like this possible. #SJ23Proud #FieldDayFun
No shortage of posts from us today (or this week, for that matter), but that just shows how much joy, excitement, and celebration fill these last days before summer break!
A huge thank you to our amazing staff and volunteers for making our annual Field Day Lunch possible!
