Preferred provider organization
In health insurance in the United States, a preferred provider organization (PPO), sometimes referred to as a participating provider organization or preferred provider option, is a managed care organization of medical doctors, hospitals, and other health care providers who have agreed with an insurer or a third-party administrator to provide health care at reduced rates to the insurer's or administrator's clients.

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.
