About Us

To carry forward the engaging programs of the Health Career Collaborative, we have assembled an exceptional team of health care professionals, physicians, public health educators, school administrators, teachers, and students. The group has a wealth of knowledge and expertise and brings together a diverse set of backgrounds, experiences and insights. In team meetings and planning sessions, there is a high level of collaboration, thoughtful listening, and great energy. Everyone shares perspectives and contributes ideas to build highly effective and inspiring presentations and learning activities for all participants.

We are grateful for the support of Aetna and Main Line Health whose generosity has made it possible to build and grow the Health Career Collaborative.
