• CMS Hosts Community Vigil to Reflect and Honor

    CMS is so grateful for the beautiful opportunity to gather together for our Community Vigil this week. We honored loved ones lost this year and the challenges we've faced while holding hope and gratitude for what we have (and have endured). Thanks to the students, parents, and staff members who shared on Monday, and for giving us hope about the days ahead. Please see the resources we have put together for healing by clicking here.
