Ending Week 1 in the best possible way…8th graders walking over to welcome our kindergarten learners and gifting them their first spirit wear, hard to tell which group loved it more! #YouBelongInD12

It’s been quite a week for our family. Harrison Francis Salsinger arrived three weeks early on July 20. From a few days in the NICU to now adjusting to life at home, he is already so loved. My family continues to grow in the sweetest of ways!

It's been a week! My baby girl married the love of her life and I couldn't be happier. To be surrounded by family and friends who are family made it all the better!

This week my baby, my only daughter, marries the love of her life. How is it possible when this is what I think when I hear, “White dress and veil?”

I kicked off Read Across America Week by bringing my favorite “assistant to the superintendent” to read with our kindergarten classes. Thank you, Parker, for making my day! #YouBelongInD12

Kicking off 2025 with a day of learning for our staff. It's always great when we can all be together in one place, and learning from each other is an even greater bonus! Thank you to our AI leaders for developing and presenting sessions on using AI. #YouBelongInD12

How does a D12 learner present when they graduate from Roselle Middle School…kind, compassionate, supportive, and ready to take on the world. A current cross country runner and his D12 graduate brother who stepped in to encourage and motivate to persevere. #YouBelongInD12

A full circle moment....anyone else recognize this VERY TALL DuPage superintendent? He has been a trusted colleague and his son (Even Taller) was one of the first students I met in D12....as a graduating senior, Henry came back and shared this thoughts with our 8th graders.
