Wiliam Bonfield, M.D., M.P.H

Chief Medical Officer, Internal Affairs, Government Programs

I have always been interested in systems. When I practiced I always thought of individuals in the context of the bigger systems that supported and frustrated them and viewed my job as helping people learn to manage those systems more effectively to accomplish their goals. My attraction to managed care was the opportunity to influence systems of care directly. I believe both our purpose and our opportunity as a managed care company is to improve systems of care so the people who use those systems have an effective, engaging and affordable experience; and so the people who work in those systems want to come to work every day.”
