    What is a GPO?

    A GPO is an entity that is created to leverage the purchasing power of a group of businesses to obtain discounts from vendors based on the collective buying power of the GPO members. In our case, the primary vendor is the wholesaler.

    Why join a GPO?

    Fiscal health is of paramount importance in today's changing healthcare market. Office Administrators and Physicians do not have the resources, time or purchase power individually to negotiate the best possible prices on their contracts. Having a GPO perform this task for them, allows them to focus on their patients and practice.
    OSI believes the time for an immunology GPO Is now.
