Tournament Organizers/Premier Tournament Organizers
A Tournament Organizer (TO) is someone who runs tournaments for their local community. Usually, he or she runs them within a weekly or monthly basis at a local store. However, a Premier Tournament Organizer (PTO) has the ability to run major tournaments and Prereleases as well in any major place at a particular time. Like Pokémon Professors, TOs and PTOs have to be 18 or older.
