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.

  • MArla Reynolds
    Marla Reynolds
    Assistant Principal

    My name is Marla Reynolds, and I am honored to serve as the Assistant Principal at Dr. Joe J. Bernal Middle School. As a proud graduate of Northside Independent School District, I attended Locke Hill Elementary School, Hobby Middle School, and Clark High School. I earned my Bachelor of Fine Arts in Dance from Texas State University and my Master of Education in Educational Leadership from the University of Texas at San Antonio. Before serving as Assistant Principal, I was the Administrator Intern at Bernal Middle School. My experience also includes serving as a Fine Arts Dance Teacher, Physical Education Teacher, and Drill Team Director at Taft High School, as well as the Dance Teacher and Dance and Drill Team Director at Warren High School. Each of these opportunities strengthened my commitment to serving students, supporting teachers, and fostering a positive school culture. I believe every decision should be centered on what is best for students. Leading through service, fostering meaningful relationships, and maintaining high expectations are essential to creating a school where every student feels valued, supported, and challenged to reach their full potential. My background in Fine Arts has reinforced my belief that students thrive when they are connected beyond the classroom. I am a strong advocate for student involvement in clubs, athletics, fine arts, and extracurricular activities because these experiences build confidence, leadership skills, teamwork, and a sense of belonging. I am committed to partnering with our families, empowering our staff, and creating a safe and engaging learning environment where every student has the opportunity to discover their passions and achieve success.
