Principal's Message

     Hi all!  Welcome to TMS!  Iā€™m Brittaney Cassidy, the principal of Trinity Middle School, and I want to take this opportunity to tell you a little about myself and a lot about our school.  This upcoming school year will be my 3rd year to be principal of TMS and my 17th year in education at Trinity ISD.  I take pride in being a graduate of Trinity High School, and I am honored to say that my children will be Tiger alumni as well!  I received degrees from Sam Houston State University with a B.S. in Academic Studies and a Masters of Education in Administration.  Trinity is my home.
      I am truly blessed to be the leader of an amazing school.  Our students participate in the National Jr. Beta Club, student council, U.I.L. academic competitions, Scrabble tournaments, TCEA Robotics competitions, football, basketball, volleyball, track, cheer and pep squads.  I have a dedicated staff of teachers and paraprofessionals who go above and beyond to educate and care for our students.  We use the TEKS Resource curriculum at Trinity ISD to ensure alignment from Pre-K ā€“ 12th grade. 
    You can follow TMS on twitter @ms_tigers and me @bcassidy5 to see all of the wonderful activities that our kids are involved in.  I love my tigers and encourage you to follow the calendar of events on our district website to see when you can come out to support and celebrate our students. 
If you have any questions, feel free to email me at your convenience.
