LaQuinci,
Kudos to you and your friends for trying to do something positive!
First, since I am probably old enough to be your mother, let me go into mommy mode. I pray that you did NOT place your given name on the 'net! While I would like to think that the folks on GreekChat are wonderful, law abiding citizens, I don't know them and neither do you! You put a whole lotta information about our self out there. Edit, please!
Now, to your question....there are a few Tau Pi Omega (the AKA chapter chartered to serve the Stone Mountain/Lithonia area) chapter members that teach in the area. As a matter of fact, there is one that I know of that works at Stephenson Middle School. I'm sure if you seek them out they will be happy to give your group a little assistance.
Good luck.
