First step, you should do some research. Registered student groups are listed in the PennClubs database. Search the database to find out if there is already an existing group with an identical or very similar mission to the one you wish to start on campus. Second step, contact the Office of Student Affairs to check if a group with a similar mission exist but may not be currently registered. With over 700 active clubs on campus each year, you want to ensure a similar group does not already exist. Once you are confident you are starting a unique group, you can register the new organization in PennClubs.
