For more than two decades, Mark Sheffield served his country as a U.S. Navy commander. Today, his mission is to help young musicians discover their confidence, creativity and passion.
As owner of School of Rock Otay Ranch, Sheffield has created a place where South Bay students can learn music, collaborate with other musicians and experience the excitement of performing as a bandThe transition from military service to music education may seem unexpected, but for Sheffield, the connection is clear. The leadership skills he developed in the Navy now shape the way he mentors students.
“This picture is from my first ship,” Sheffield said while reflecting on his military career.
“Everything about myself, everything about our country, I learned a lot about the world.”
During his Navy career, Sheffield traveled the world, was deployed five times and spent a year in Iraq. After years of service overseas, he eventually returned home and settled in Chula Vista, where he began a new chapter focused on helping young people grow through music.
Asked why he chose to settle in Chula Vista, Sheffield said, “You bet, I dropped it here in Chula Vista.”
School of Rock Otay Ranch opened in 2020 with a different approach to music education. Rather than focusing only on traditional lessons, the program combines individual instruction with group rehearsals, allowing students to learn together, build confidence and prepare for live performances.
For Sheffield, that teamwork is familiar territory.
“Personnel development,” Sheffield said when describing one of the biggest lessons he carried from the military.
That philosophy has become part of the school’s culture, where students learn that music is not only about playing an instrument but also about listening, cooperating and becoming part of a team.
Students at School of Rock Otay Ranch have opportunities to learn a variety of musical styles while rehearsing and performing together as bands. The collaborative approach encourages students to build confidence, develop their musical abilities and gain experience performing before live audiences.
Although Sheffield said he does not play an instrument himself, he understands the importance of helping others discover what they can accomplish.
“Absolutely, absolutely. I love seeing people become what they want to become,” Sheffield said.
That mindset has carried over from his years of military leadership into his role today.
Instead of leading sailors, he is helping young musicians find their confidence, express themselves and discover their own potential.
At School of Rock Otay Ranch, students do more than take lessons. They rehearse together, perform for audiences and experience what it means to be part of a band. The goal is not simply to develop stronger musicians, but to help students build confidence, teamwork and skills that extend beyond the stage.
For Sheffield, the mission has simply changed.
After decades spent protecting and serving others, he is now helping the next generation find its voice — one song at a time
