Because of student interest, Texas A&M - Corpus Christi established a greek system from scratch in 1998, with 3 fraternities and 3 sororities (there were no locals before). I helped with the colonization, so I might be able to answer some of your questions, but you should probably contact their Greek Life Office:

I believe the colonization has been very successful, and hopefully they can provide you with some helpful guidance. Good luck!
