Dr Brenner owned and operated a solo-practice, urban family medicine office that provided full-spectrum family health services to a largely Hispanic, Medicaid population including delivering babies, caring for children and adults, and doing home visits. Recognizing the need for a new way for hospitals, providers, and community residents to collaborate he founded and has served as the Executive Director of the Camden Coalition of Healthcare Providers since 2003. Through the Camden Coalition, local stakeholders are working to build an integrated, health delivery model to provide better care for Camden City residents. Dr. Brenner’s work was profiled by the writer and surgeon Dr. Atul Gawande in an article in The New Yorker entitled “The Hot Spotters” and in an episode of PBS Frontline. In 2013 he received a MacArthur award.
