The landscape of public health is shifting dramatically as demands grow for impact and approaches that address the social determinants of health. It is in this context that Public Health 3.0, the Health Impact Pyramid, and the Collective Impact Model have emerged. From these has come the need for public health and its leaders to learn to think and act as a chief health strategist. What does this mean? How do we go about it? This webinar will provide context and examples of implications while laying the foundation for change leadership.
