Delts Talking About Alcohol (DTAA) has paid Delts who travel to every Delt chapter once a year. Every Delt must take the program.
It was the first alcohol awareness (not anti-drinking) program in the Greek world to get government support in its development. I have taken it as an advisor, and it's pretty well done.
We have shared it with a number of national fraternities and sororities who use it under their own names.
ETA it sounds very much like AGD's above. It may be that Alpha Gam is one of the nationals using DTAA -- but I don't know for sure. They may have developed their own program -- they do sound very similar, though.
