Meet the Students' Union Team

The St. Jerome's University Students' Union is here to support your experience as a student at SJU and the University of Waterloo. We look forward to connecting with many students at the university so that we can share your concerns at St. Jerome's Board of Governors, WUSA Council, St. Jerome's Senate Council, and Committee meetings. You can learn a little bit about us below to help you recognize us and reach out and talk to us when you see us on campus.


You can always stop by our office (located in SJU's Sweeney Hall, Fireplace Lounge) to chat or share your ideas; reach out using our president's email address at; or connect with one of the other members of our executive listed below. Keep an eye on our social media accounts, particularly Instagram - @sjustudentsunion, to find out about upcoming events!

Hi everyone! My name is Caitlin Roehrig and I am honored to be your vice president academic this year! I am entering my second year of UWaterloo's Psychology and Business co-op program and am eager to be involved in this year’s Union. My main focus this year is to integrate YOUR ideas into the St. Jerome's academic world of study and maintain the promotion of mental, physical and emotional health. I want to help St. Jerome students have the smoothest year possible academically and work through any concerns students have regarding their particular programs at SJU.

Tristan Chen, Communications Officer
Tristan Chen
Office Hour(s): Meetings available upon request.

Hi SJ! My name is Tristan and I am your Students' Union Communications Officer for the 2022-2023 year. I am currently about to start my fifth and final year at SJ and am doing a Visual Culture Major and Minors in Political Science and Digital Arts Communication. I came to SJ alone and was immediately welcomed by so many people, not only fellow students, but also student leaders and staff as well. Essentially, it felt like a home away from home.


In this position, I believe that I have responsibility to not only the voice of the Union but that of all of SJU's students too. My promise is that as your communications officer, I want to make sure your voices are heard, by ensuring that the Union knows and works to make sure systems that are working remain in place and to advocate for all your concerns. I hope that by doing this, all current, incoming and future SJ students can have that same amazing feeling that they not only belong here, but are also in their own home away from home.

Hello! My name is Caitlyn and I am your project manager and administrative officer. As your PMAO I work on several initiatives that help St. Jerome’s student life, such as The Menstruation Station and the Farmer’s Basket program. I am very excited to bring lots of fun and exciting initiatives this year as well as improve old ones to make them more accessible to our student body. If you have any ideas that you would like our Union to implement do not hesitate to reach out! I am a voice for your concerns and I want everyone to be as involved as they can with the exciting events that I have planned for this year!
