Justus was an amazing and devoted friend to so many and graduated 8th grade on May 18, 2024.  Throughout Justus cancer battle he inspired many people with his strength and determination.

    Justus has made a difference in so many lives. I’m grateful to have known him while he was at Coulee Christian. Each time he was seen in the health office he always remained positive. He was a wonderful guy to have around. Always with a smile on his face no matter what he was facing. My heart aches with you.

    That was a beautifully written tribute to him. It must have bern so painful to write. I love Justus and each of you. He was incredibly strong and is the definition of perseverance. He has parents who walked alongside of him sharing every pain and celebrating all his moments. His siblings shared in it all too. I love you, Auntie Honey.

    I got the honor of spending time with you and your family at the lighthouse retreat in Florida with my daughter Hailey and son Gavin. Though your story reminded me of my son’s battles, it was a healing and eye opening experience to spend that week with you. It was if your family helped me more than we were there to serve you. You will be missed, but your memory will live on. You will not be forgotten…our love to you through our tears of sadness knowing we will have to wait to see you again. Love you Justus Heise
