Today, Alpha Delta Gamma operates nine active chapters at private and public colleges across the United States, stretching from Los Angeles, California, to Atlanta, Georgia.

Active chapters annually support at least one function for the benefit of orphans such as a Christmas toy drive or spring picnic.
