For me, going Greek was much more than just making friends and creating an atmosphere for my college experience. I joined a house in the hopes of getting more involved on campus (and I have, becoming a BGR supervisor and PUDM executive). Even if your end goal for joining an organization was to join more organizations, many people throughout the Greek community end up participating in other campus groups. In fact, members of the Greek community tend to be the individuals who hold leadership position within organizations. But there also seems to be a great divide with in the Greek community. Either you have the incredibly involved members or those who do absolutely nothing. So how do we change that? How do we get members to start participating on campus?
On of the major deterrents for people to branch out is not knowing anyone. Asking a brother/sister to come check out a club you are involved in will allow them to ease into involvement and give them a foundation to build off of.
Another way to increase house involvement among your house is to be passionate. Make sure your house knows and sees your passion for the organization you are involved in and tell everyone why you love it. Passion is addictive and infectious!
A way that usually pays off for me, but requires work, is approaching your brothers or sisters one-on-one. This method requires you to do some research and match a club with your brother/sister. Once you find about two or three organizations that coincides with their interest and personality, you need to speak with them in person. Talk about how you think that they would enjoy the organization greatly and the benefits that they would get from it.
There are many other ways to increase chapter involvement on campus, as long as you use creativity, make it individualized, and show your passion. One person really can make a difference. And if five brothers/sisters say no, don't let that discourage you; there are some people that just don't want to be involved. But for every few nos you will get a yes; and with more members in your house getting involved, there will be more people to help you to encourage house involvement on campus.
