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.
Lead petty officer
A leading petty officer or LPO is a title given to the senior petty officer in the pay grades of E4-E6 in the United States Navy and Coast Guard. A LPO is the chief petty officer's "go-to person" for the lead of the division and to help with administrative tasks. While most often the leading petty officer is the senior ranking petty officer, this is not always the case. The LPO is chosen by the "leading chief petty officer" or LCPO (grade E7 or above) for his or her demonstrated leadership abilities and knowledge in the job or rating.
