Hi Latasha, and thanks for contacting CTB.
I know very little about resources for information about system management in public health, but I was attending a meeting this morning that included the Assistant Director of our city-county Health Department. When I asked her for advice, she suggested that you contact the Center for Disease Control (CDC) and Emory University for leads to the information you are seeking.
I suggest, also, that you take a look at our Table of Contents: Chapter 2, Section 13. It provides one model for strengthening public health.of a community.
