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.
The Philharmonic Orchestra
The Philharmonic Orchestra (TPO) is an amateur orchestra in Singapore, initiated as a project by Maestro Lim Yau in 1998. The orchestra consists of adults who have a keen and serious interest to perform music. Formerly known as the Philharmonic Chamber Orchestra Society (PCOS), the group became The Philharmonic Orchestra (TPO) to better reflect its intention to perform both symphonic and chamber works.
