Our main school website at gcmsk12.org has been updated to a new look! As we move forward with our new site, we will no longer be using the GCMS apps that were previously available in the App Store and Google Play. If you have these apps, you may remove them. If you would like to add a mobile friendly version of our new site to your homescreen, directions are linked below.
