Since they're often the first person students will encounter, greeters will be ready to answer questions and address concerns as they arise.
Greeters will assist students arriving from airports or bus stations to navigate to the appropriate pick up area. They may also be the source of information about planned activities and will direct students to the right location or person to answer more in-depth questions.
