The Latino Commission on AIDS developed the Navigating Changing Environments: A Leadership Toolkit as part of its capacity building assistance work with communities in the Deep South of the United States as well as Puerto Rico and other states with Latino populations. However, the toolkit is meant to be used by community organizers, advocates, healthcare providers, community-based organizations, faith-based organizations, and others that work with marginalized communities impacted by HIV/AIDS who are looking for examples, approaches and tools utilized by those leaders who have been hard at work mobilizing their communities in a variety of contexts. The Commission recognizes the challenges of working with marginalized and emerging populations moving into, and interacting with, any community. We invite you to use the contact information that follows below. It is our hope that users of this toolkit will provide us with feedback on the usefulness of this resource in their community and the leadership efforts that they undertake.
