He brings 19 years of experience to education and has served in a campus administrative role since 2006. Vaglienty began his education career as a Special Education teacher and coach at Watkins Middle School in Cy-Fair ISD from 2001 to 2006. He then joined that campus administrative team as Assistant Principal and served in that role from 2006 to 2009.


He continued as an Assistant Principal at Arnold Middle School in Cy-Fair ISD from 2009 to 2011 before becoming an Assistant Principal (2012 to 2015) and a Curriculum Principal (2015 to 2017) at Nimitz High school in Aldine ISD before landing in Tomball.


“My previous junior high experience allowed me to build a passion for this age group of students and to serve as a role model for students as they transition into high school,” Vaglienty said. “I look forward to supporting student and teacher growth and serving an amazing school community in Creekside Park Junior High.”

Vaglienty earned his Bachelor of Arts in History from the University of Houston and his Master of Education in Administration from Sam Houston State University.


“Tomball ISD is a special place to work because of the students, great teachers, a super supportive community, and amazing innovative leaders at all levels that passionately care about students and I look forward to the opportunity to lead the CPJH campus.”
