Principal's Message

Building Principal - Charles A. Mims, Ed.D.


My name is Charles Mims, and the 2022-2023 school year marks my fourth year as principal of Rio Vista High School.  I have served students in many educational roles throughout my career, including as a classroom teacher, as a coach of multiple sports, as well as an administrator.  I'm looking forward to an excellent school year working with some of the best educators and students in Texas!  As we navigate through this school year, I hope that my staff and students experience many successes in their academic, extracurricular, and personal endeavors.
