ION contracts directly with leading pharmaceutical and biotech companies to support their products within the organization’s membership. As a value-added group-purchasing organization, ION excels in educating oncologists about the clinically-appropriate utilization of manufacturers' products. Members are always encouraged to exercise their own independent professional judgment related to the usage of all therapeutic agents.

ION uses the nation’s leading oncology-specific distributor, and one of its sister companies under the AmerisourceBergen Specialty Group umbrella, Oncology Supply http://www.oncologysupply.com/, to fulfill all orders.
