Younger Member Group

If you are an ASCE member aged 35 or younger, ASCE National considers you a Younger Member – including student members! The Nashville Branch’s Younger Member Group would like you to be a part of what we do. Our mission is to create opportunities for our Younger Members to develop professionally and personally through active participation in social, educational, and community service events. We typically have at least one event every month! To learn more about what we do, feel free to review our 2014 Annual Report and our Bylaws.
