John Markovetz is an experienced educator with 23 years teaching in Catholic schools. Raised in the Catholic faith and blessed with a Catholic education from elementary through high school, he has valued the opportunity to serve as a teacher and administrator in Catholic schools.

His career as an educator began at Antonian College Preparatory High School in San Antonio where he first served as a substitute teacher and later taught Geometry for two years. In 2006, Mr. Markovetz accepted a faculty position as a math and science teacher at The Atonement Academy where he taught classes in grade levels 6-12.

Mr. Markovetz earned his Bachelor of Arts degree in Economics, Math, and Physics from the University of Colorado, Boulder, along with his Air Force commission from the ROTC program. He later completed his Master of Arts degree in Computer Resources Management from Webster University.

Serving the homeschool community in the Catholic, classical tradition is an opportunity Mr. Markovetz is grateful to be a part of and is looking forward to a successful and rewarding experience for all students and families.

Justin Olinger is a military veteran with a lifelong passion for health and activity. His journey began in childhood when his parents encouraged him to participate in sports such as wrestling, soccer, and cross country. Although he never considered himself an athlete, Justin remained active throughout his youth. Growing up smaller in stature, he occasionally faced bullies who doubted his abilities. Determined not to let their words define him, he embraced weightlifting—introduced to him by his father—which strengthened both his body and his confidence. Through this experience, Justin discovered that personal growth is always possible and that everyone possesses untapped strength waiting to be found.

After graduating high school, Justin enlisted in the U.S. Air Force, where he continued to advance his knowledge of health and fitness. He served as a Physical Training Leader (PTL) for fellow service members and also trained as a martial artist. Following his military service, he pursued a degree in Kinesiology—a field he continues to study today. Justin remains dedicated to coaching both children and adults, driven by his mission to help others discover their own inner superhero.
