About Me

Upon completion of my doctorate in 1996 I was encouraged to apply for an adjunct position in the Center for Education and teach the School Design and Architecture course. At that time, I was working as a principal in a large urban school district.

During my tenure in the public sector I served as a principal, supervisor, public relations coordinator, facilitator with the Panasonic Foundation, and teacher. As my Widener students hear at the beginning of each course I teach, I tell them I'm Constructivistic, Transformational, and Inquiry based in my teaching style and will encourage their collaboration and creativity within all classroom projects and assignments.

Research Interests

Effects of mediation using student peer mediators in the prevention of bullying and the long-term effects of prevention and intervention substance abuse strategies which was a longitudinal study for my dissertation.
