The Glenbrook High School Foundation

The Glenbrook High School Foundation can also offer you many valuable services. The Glenbrook Foundation has a comprehensive Alumni Database, which may provide you with additional information on alumni contacts.  The Foundation will work with you to create a database of classmates, which can be accessed by future reunion planning committees. In addition, the Foundation can provide you with a list of local restaurants and venues that have hosted reunions in the past and provided a discount. Lastly, it can help you set up a social media platform to connect with your classmates and share pictures and information after your reunion has concluded. For details, contact:

Dr. Jim Shellard
Director of Development
