at the far end of this group is my boss, bill hoagland. bill is the senior vice president at bpc. he came here from cigna, where he was vice president of public policy. but most of his career was spent on the hill, where he was director of budget and appropriations for the office of the then senate majority leader bill frist. thank you all so much for being here. jeff, i'm going to start with you. we have talked about high-level framework, big picture models, and i want to go to the real world for a minute. more than probably any of us on the stage here, at least, you have the most experience with a number of the players on the ground who are really seeking to implement some of these experimental and new models of care that integrate clinics and communities. >> this is an exciting opportunity to see where prevention fits in the health care system but it is always important that we have a good conversation about how we value things and it isn't just about cost-saving but better health outcomes. to measure and prevention isn't just determined by how it would save health care costs.
