“As an oncologist practicing in a small group of five physicians, I need to stay informed of major developments in the business of oncology in order to effectively manage our practice. ANCO does an amazing job in sharing best practices and providing relevant, timely information. I also applaud ANCO for being the voice of Northern California Oncologists in its governmental advocacy work, which I have seen firsthand as a board member. Every oncologist in our region should be an ANCO member to continue to fortify our mission of providing quality care to all.”
