Degrees and Certifications:

Mr. Derek Leary

I am excited to serve our Rountree families as an Assistant Principal. This is my 3rd year in Allen ISD and my 21st year in education. I have previously taught 5th and 6th grades and also served as an assistant principal, principal, and in student services.

I was born in Cedar Rapids, Iowa, and moved to Texas in 2001. My education includes a Bachelor’s degree from The University of Northern Iowa and a Master’s degree from Illinois State University. In my free time, I love to watch sports, travel, and spend time with my family.

I am so blessed to get to work with such great teachers, administrators, students, and parents! I am looking forward to working with you and your child!

Derek Leary, Assistant Principal
