As many of you may already know, a valued member of our Nonnewaug school community, Jon Cheung, was recently diagnosed with Leukemia. Just as he always has done in the classroom, on the sports fields, and in life, Jon is giving his all in this fight and the whole community is behind him. Our chapter of the Math Honor Society, of which Jon is a member want to show support and help raise funds to assist with the medical costs that his recover process involves so that him and his family can focus their attention on his health. To that end, we have planned a charity 5K walk/jog/run on Nonnewaug's campus for the 23rd of May. We hope you will show your support by signing up and enjoying a fun race with music, games, food, and more. If you have any questions, please email [email protected] or text 860-605-3730.
