For more than 14 years, Mary Jo Malino has worked as a substitute educator in the Charleston County School District. Mary Jo brings passion, adaptability, and a deep commitment to students—especially at the high school level and within the Junior ROTC program.
We sat down with her to talk about how she got started, what she loves most about substitute teaching, and her advice for others considering this rewarding role.
I’ve been with Kelly Education in Charleston County since 2012. Before moving to Charleston, I lived in California, where I was an elementary school teacher teaching second and third grade. When I came here, I decided to try substitute teaching—and I found my place quickly.
The little ones are adorable, and I loved teaching elementary school. But once I started at the high school level, I realized it was a whole different element. You can really talk with students. You can have discussions, debates—even negotiations sometimes! They’re challenging, but you see their curiosity and their desire to understand what’s happening in the world. That critical thinking piece is something I really enjoy.
I had a 10-month long-term substitute position in the Junior ROTC class, from December 2024 through September 2025. I’ve been affiliated with the Junior ROTC program since my kids were involved, and it’s just an incredible experience.
The students learn leadership skills, time management, interview skills, and the importance of community service. I enjoy watching them grow from freshman year through senior year—it’s incredibly rewarding. The whole goal is to help them go out into the world and make a difference.
Flexibility is one of the biggest benefits. I do what works best for my schedule. I also own a travel agency and work from home, planning cruises, destination weddings, and multi-day trips. Substitute teaching allows me to work around my business, my appointments, and anything else I have going on. I can work as a substitute teacher when I want to—and that flexibility is huge.
I would tell them to try it—and try everything. Different grades, different schools, different programs. Every classroom is different, and it’s not one-size-fits-all. Not everyone will feel comfortable in every setting, whether that’s elementary, high school, band, physics, or ROTC.
But you won’t know what fits you best until you experience it. Substitute teaching gives you that opportunity to explore, find your comfort zone, and grow along the way.
Mary Jo Malino’s dedication, flexibility, and passion for student leadership make her a shining example of the impact substitute teachers can have. Congratulations to Mary Jo on being named a Kelly Education Substitute Teacher of the Month in Charleston!
