Welcome to the 2025-2026 school year! 

I am so privileged to begin my 12th year as the Principal of Mullanphy.  I have served in SLPS since 2004 as a teacher, instructional coach, and assistant principal on several campuses, working with students from PreK-12th grade.  It is a joy to see the accomplishments of our students over the years! I am very thankful for the supportive community of family and staff that surround our students to see them through to success.

We are excited to launch our school year and Explore! Learn! Grow! Together!  Our team will be working hard to create an environment for students where they feel they belong and are able to gain all of the skills they need to be successful academically and socially.  Students will be able to learn and practice valuable skills throughout their day. We look forward to partnering with you as we work to create a safe and welcoming school environment, We ask for your support at home to practice these important skills, bring your child to school every day, and let us know when you need extra assistance.  

Should you ever have any questions, concerns, or needs, please contact me at Mullanphy (314-772-0994), on my district cell phone (314-437-8396), our school app, or via email (kelli.casper@slps.org).
