I've been on the board of my alumnae chapter for about 4 years...so I had a chance to watch & learn what works & what doesn't.
We have 200 members. Our Founders' Day brunch is usually the most attended event, but a lot of our Nite Kites (social hours) bring out a fair number of Thetas...mostly younger. We even had an exchange with the local Sigma Chi Alumni chapter. It went really well!

We hope to have photos up soon..there are currently some in the newsletters. Our webmaster is getting married very soon, so she'll do a big update after the honeymoon!
