I was the president of the eta mu chapter of ATO at florida atlantica university. I have spoken with our national accountant, advisors, even the damn CEO of ato. I will say this, there is almost no benefit after college. I even asked our national advisor why I should be an alumni of ATO and what the benefits are after college and literally told me only one benefit and that was it.
While your in college I feel a lot of people are just curious on what the hell greek organizations actually do, hence the curiousity to learn some of the majority not true sales pitches these orgainzations throw at you.
It is a business above all, you don't pay guess what your not affiliated that semester, your money is used for generating more members, hence more parties, hence larger amount of people joining in the future for growth of the member size/member dues.
All I say is this, check it out and if you have any Q's about going greek feel free to IM me and I can give you the input. I know the in's and out's with this shit.
