Response: Re: Social Justice as the Moral Core of Family Medicine: A Perspective from the Keystone IV Conference ================================================================================================================ * Steven A. Schroeder *To the Editor:* It is good to hear of these examples of collaboration between local public health agencies and family medicine. Given that the Keystone IV Conference focused on health care delivery issues, my “partial list” of potential allies for family medicine was limited to clinical disciplines. I fully agree with Dr. Schlenker that abundant opportunities to improve population health exist beyond those examples, including local public health agencies, state and federal government, advocacy groups, and many others.
