He received a Bachelor's degree in History and continued his education by earning a Master of Education in Education Administration from Grand Canyon University.

Mr. Guilbeau’s professional journey began in January 2012 as a permanent substitute teacher at Inspire Charter Academy in Baton Rouge, Louisiana, in a 6th-grade self-contained classroom teaching all subjects while searching diligently for a permanent teaching position. After a semester of hard work with his 6th-grade students, he was eventually offered the permanent position at Inspire with the opportunity to teach those same students again next year in 7th grade.

During his time as a teacher in Baton Rouge, Mr. Guilbeau taught grades 6-8 in English Language Arts and Social Studies. He was a grade-level lead teacher, mentor teacher, summer testing coordinator, and head boys and girls basketball coach. In 2015, Mr. Guilbeau accepted an opportunity to become the Assistant Principal at Advantage Charter Academy in Baker, Louisiana. During his time as a school leader in Baker, Advantage was recognized as a top gains school for the 2016-2017 school year on the Louisiana state test.

During the 2017 school year, change came as Mr. Guilbeau uprooted himself and moved to California to be with his wife, who was attending business school at Stanford University. While in California, Mr. Guilbeau served as a school leader at Summit Denali, serving grades 6-10 as the Dean of Culture and Instruction and head boys basketball coach.

After two great years serving students and families in California, Mr. Guilbeau and his family relocated permanently to the Atlanta metro area as he continued his career in education in a new city. Serving most recently as a Director of Instruction for 3DE Schools, Mr. Guilbeau worked with a network of high schools across the Atlanta Public Schools, Dekalb County Public Schools, and the Gwinnett County Public School districts, coaching and developing high school teachers.

Outside of school, Mr. Guilbeau enjoys spending quality time with his wife and two-year-old son. He is an avid crossfitter, fisherman, and die-hard New Orleans Saints football fan. Mr. Guilbeau is an outgoing, energetic person who loves to talk and build connections with others.

Mr. Guilbeau believes all students can succeed. Fostering a community with specific goals and high expectations and leading with a sense of urgency, he believes a great school can be a community that produces not just members but leaders in society. Mr. Guilbeau is delighted to join the Centennial team and eager to work to become a contributing member of the Centennial community
