Want to help ATLAS grow?


We continue to meet with interested state agencies from many states across the country and hope to add additional states to ATLAS as we work towards our goal of being in all 50! More information will be available on which states we will be adding in the coming months, but we are always interested in talking with new states we may not already be connected to.

We are continuously in talks with state agencies and local stakeholders about expanding ATLAS, and welcome any suggestions you have on individuals to reach out to. A typical agency we’d partner with might be a state health department or a bureau of alcohol and substance abuse services. If you know of anyone interested in learning more about bringing ATLAS to the state, please reach out today at
