Initially, I joined as a way to make new friends and find people with similar interests. As I became a part of the brotherhood, I found that I could work on more professional skills in terms of working different positions in the organization. All of the positions I have held have taught me things that I can use later in life.

Triangle taught me how to lead, through professional development and executive position opportunities. The work I’ve put into this organization has reciprocated tenfold by providing me with the network, tools, and skills I need to further my career. I am certain that joining has been the single greatest decision in my life.

Five years ago, I wanted nothing to do with joining a Fraternity.  Here I am now, 5 years later, in Triangle, serving as a founder and President of a new colony. Triangle has a place in my heart now, and it will characterize my time in college.

Being in Triangle I’m surrounded by guys who want to make the most of their college experience. They’re guys who help each other with classwork, guys I go to football games with, and guys I enjoy being around. Joining Triangle Fraternity was the best decision I could have ever made.
