      Christopher Tiritilli

      Phone: (630) 968-6155


 My name is Christopher Tiritilli, and I am so very excited to be the new principal of St. Mary of Gostyn Catholic School.  Professionally, I am also excited to continue my administrative career.  I have many great experiences to draw on from my past two years as Principal of Holy Family Catholic School.  Throughout my time in education, I have been able to confirm my belief that successful schools require strong leadership. I hope to provide that for SMG by empowering teachers and students in order to achieve success. 

Prior to my administrative career, I was the 6-7th grade Social Studies, Reading & Religion teacher at St. Joseph School in Downers Grove.  I began my career in education at O’Neill Middle School in Downers Grove, where I was a special education instructional assistant, as well as long-term substitute teacher and coach.  Each of my teaching experiences has taught me many lessons and helped prepare me to lead SMG forward.

I believe in transformative leadership, which invites input from all stakeholder groups.  Building strong relationships within our school and surrounding community is critical.  I am looking forward to getting to know everyone and sharing ideas as we work together to support our students. 

I strongly believe in a safe school environment, positive school culture and clear communication.  If you should have a concern or question regarding a policy, procedure, or situation, please contact your child’s teacher or me at the school office.
