OPN has been a leading oncology partner for 25 years, serving as a benchmark for value-based cancer care in a variety of US regions.

Oncology Physicians Network (OPN) is a Management Services Organization (MSO) focused on cancer care. OPN has been extremely successful at developing systems and capabilities built around delivering quality, value-based cancer care to the community. It offers its partners a flexible array of services to meet their unique oncology care needs, meeting the partner in a way that is suited to their particular structure and healthcare focus. This approach translates into a sustainable solution for both payers and providers with improved cancer care for patients.

OPN has a long history facilitating value-based cancer care for the community. Initially founded as Greenwave Health Technologies in 1999, OPN developed the Southern California Oncology Associates (SCOA) network which transformed California community-based oncology care in the region. OPN has grown markedly over the past two decades and now manages the oncology needs for over 1.7 million beneficiaries. The company is currently adapting its model in other regions and is operating in Oregon and Washington.
