Tony Porter is a co-founder of A Call to Men. I’ve had the pleasure of hearing him speak before, and TEDxWomen has hosted him in the past. Along with the video they have a conversation with him posted on their site. Click through to watch the presentation.
PreventConnect also has an archived session in which he was a featured presenter back in May, Prevention as Social Change: Bridging Sexual and Domestic Violence and Social Justice Movements. Search his name on their site for several other archived items, as well.
