My name is David La Boy and I am excited to serve as the Associate Principal of Dr. Joe J. Bernal Middle School. I received my Bachelorโ€™s degree in Family & Consumer Sciences from Texas State University-San Marcos (Eat โ€˜em Up Cats!) and my Masterโ€™s degree in Educational Leadership from Texas A&M- San Antonio. As a product of Northside, I am very passionate about serving the students and community of the very district in which I was raised. I previously served as the culinary arts teacher at Stevens High School, Career & Technical Education department coordinator and culinary arts teacher at Harlan High School, Administrator Intern at Pease Middle School, and most recently Assistant Principal here at Bernal. I am looking forward to building strong community relations and continuing to guide our students down the path to success in and out of the classroom.
