📣Meet Your TCS Team📣
Sherri Mangum
•Hi, my name is Sherri Mangum. I have been married to Kevin Mangum for 38 years. We have four grown children and 4 Grandsons. We have lived in Habersham County for 18 years. I will be starting my 16th year here at Trinity. My husband and I developed the Bible Curriculum for the school. I am very proud and excited to teach God’s Word year after year. I hope to make many disciples that love and follow the Lord, that are grounded in their faith, and that go beyond the doors of this school and make even more disciples! I love to teach here where I can pray and be bold in the classroom for Jesus! I love the smaller class sizes where I can get to know the students and encourage them on a personal level in their faith. I am also a Children’s director at River Point Community Church, where my husband Pastors. I love to go on mission trips, read, and make family memories!

•*Hi everyone! My name is Celina Chitwood, or Coach C depending on who you talk to 😉. My husband, Jo, and I will celebrate our 23rd anniversary this October and we have 6 wonderful children, Owen, Hanna, Nathan, Rilyn, and Garrett and the recent addition of our son in law, Tyler. I joined TCS originally as the assistant coach for the high school volleyball team 4 years ago. Since then I served as a long term sub before joining the staff full-time 2 years ago. This will be my 3rd year serving as a teacher, 2nd as head of the volleyball program, and my first full school year serving as the athletic director. I am looking forward to seeing what God has in store for our school this year!
Robert Barron
•Hi! I’m Dr. Robert Barron, and I’m excited to begin my second year teaching at Trinity Classical School.
I have lived in Habersham County my entire life and am a proud graduate of Cornelia Elementary School and South Habersham High School.
In June 1972, I married my high school sweetheart, Nancy. Together we were blessed with two wonderful children, Jeff (born in 1974) and Anna (born in 1983), who have given us five cherished grandchildren.
I earned my Bachelor of Science in Education from Western Carolina University in 1972, completed my master’s degree at the University of Georgia in 1976, and received my doctorate in Science Education in 1987.
I began my teaching career in the Science Department at Habersham Central High School in 1972 and retired in 2008. Following retirement, I continued serving the Habersham County School System, where I am now in my eighteenth year.
From 1976 to 2001, I also served as an adjunct professor at Truett McConnell University, teaching all four levels of Biology as well as Ecology.
In the fall of 2001, I began teaching at Mountain Education High School, where I remained until the COVID-19 pandemic brought classes to a halt.
From the fall of 2010 through the end of the 2023–2024 school year, I had the privilege of teaching at Tallulah Falls School. During my time there, I taught Sophomore Biology, College Biology, Human Anatomy & Physiology, and College Prep Physics.
In March 2022, my amazing wife, Nancy, passed away due to complications from systemic lupus. Although I miss her deeply, I am grateful for the many wonderful years we shared together.
Today, I reside in Cornelia with my daughter and her family. I look forward to another wonderful year at Trinity Classical School and the opportunity to invest in my students both academically and personally.
