Joseph Petraglia
Joseph approaches public health and behavior change from his work in rhetoric and learning theory. He sees behavior change as a largely persuasive process in which members of the public need to articulate for themselves their barriers to change and identify their own solutions. Joseph established GHC in 2003 and provides input to GHC projects and strategic goals.
