On or about March 8, 2003, the National Board of Alpha and Delta Psi Omegas officially formed a Regional organization structure.

The Regions are:

REGION 1: Washington, Oregon, Wyoming, Alaska, Idaho, Montana, California, Arizona, Hawaii, Nevada, Utah

REGION 2: Colorado, Iowa, Kansas, Minnesota, Missouri, Nebraska, North Dakota, South Dakota, Illinois, Indiana, Michigan, Ohio, Wisconsin

REGION 3: Connecticut, Maine, Massachusetts, New Hampshire, Rhode Island, Vermont, Maritime Provinces, Maryland, Delaware, DC, New Jersey, New York, Pennsylvania

REGION 4: Alabama, Florida, Georgia, Kentucky, Mississippi, North Carolina, South Carolina, Tennessee, Virginia, West Virginia, Puerto Rico

REGION 5: Arkansas, Louisiana, New Mexico, Oklahoma, Texas

The new Regional Representatives were charged with increasing activity and organizing conferences among the casts in their respective Regions.

As this is relatively new, the details are still being fleshed out and will be added here over time.
