Hello everyone, and welcome to Pi Sigma Epsilon, Delta Omega Chapter at Illinois State University! A huge thank you to all of our members for not only allowing me to be in the position of President of our amazing and prestigious organization, but also trusting me to be your leader for 2023.


I first joined this chapter my first semester of college looking for a group of like minded and driven individuals. Not only did I find just that, but I found a group of friends that push me to grow and be the best version of myself everyday. PSE is a place tailored for growth, but comes with so much more. This tight knit community is supportive and fun all at the same time. As we continue to grow my goal is to continue to improve upon this even more. 


My main focus for this year is to work closely with each and every one of our members to find the best ways for each of us to find more success and grow together. Our greatest resource is each other, so working with everyone to find solutions and generate new ideas allows for everyone to be included and share the success. This also improves communication and trust between our Executive Board and our members resulting in an efficient, smooth running organization.  


I am beyond thankful and appreciative for the opportunities this organization has offered me and I am extremely excited to lead my friends into another great year full of success and obtained goals. Thank you for visiting our website. I encourage you to look more closely at what we have to offer if PSE sounds like a place where you can fit in. If you have any questions, feel free to reach out to me directly at!

-Ian McAllister, 2023 Delta Omega President
