Meet the Assistant Principals

Monta' Jeffley - 6th & 7th Grade Assistant Principal

My name is Monta’ Jeffley, and it is with great pride that I serve as an Assistant Principal at Field Middle School. I obtained a Bachelor of Science in Kinesiology and a Master of Educational Leadership, both from the University of Texas at Tyler.

I am entering my 12th year in education and my 4th year with Carrollton-Farmers Branch ISD. I began my journey in CFBISD as a teacher-coach at Creekview High School, where I taught Geometry, Fundamentals of Mathematics, and provided inclusion support. I was also honored to serve as Creekview’s Head Boys Track Coach.

After two years at Creekview, I transferred to Ranchview High School, where I taught Geometry and served as the Special Teams Coordinator for the football team. Now, I have the honor of stepping into a campus leadership role here at Field Middle School. I am excited about the opportunity to work with—and continue to serve—the brilliant students of Carrollton-Farmers Branch.

If you have any questions or concerns, please don’t hesitate to contact me at jeffleym@cfbisd.edu.

Christin Siller - 6th & 8th Grade Assistant Principal

With 23 years of experience in education, I am proud to serve as an Assistant Principal at Vivian Field Middle School. Over the course of my career, I have taught middle school for 13 years and held roles as a reading interventionist and instructional coach. I am a student-centered leader who is passionate about creating an environment where every student feels seen, supported, and empowered to succeed.

Outside of school, I’m a proud mom to two amazing children. I enjoy traveling, reading, and cooking in my free time. I truly believe that the students and staff at Vivian Field are the best in the state, and I’m honored to be part of this incredible school community.
