Mariandl Hufford, President & Head of School, Miami Country Day School

Invest: sat down with Mariandl Hufford, president and head of school of Miami Country Day School, to discuss mission-driven culture, global learning, and how independent schools are adapting to new expectations from families and employers. “At the end of the day, my job is two things: advance the mission of the school and take care of the adults on campus so they can take care of the kids,” Hufford said.

How do you bring Miami Country Day’s mission to life across all grade levels, and how does it shape the school’s culture?
We are an incredibly mission-driven school, and visitors feel that quickly. Our mission is reinforced through our core values and the way we talk about them with students from the earliest grades through graduation.

In the early years, students learn what the values look like in daily life. As they grow, they are recognized for living those values, and we reinforce the Spartan spirit as part of who we are. Culture is not separate from academics. It is how we define excellence and community.

Our Board of Trustees re-adopted the mission at the end of 2020, and we built shared language around it, including a phrase we repeat often: every student, every day, everywhere. Because we start at age three and go through age eighteen, we are making a fifteen-year commitment to a child and a family, and the language helps keep that responsibility front and center.

A key practice is the Spartan Pledge. Every adult signs onto it, and it is recited at the beginning of meetings across the school. It is a simple reminder to put children at the center of what we do and say and to model values like purpose, respect, compassion, honor, and wisdom.

What prompted the extension of the Spartans Around online program, and how do you see digital learning intersecting with traditional education going forward?
The school is forward-looking by design, and COVID pushed every school to learn faster. During the pandemic, our global community dispersed, and students were logging in from many places. We asked ourselves what lessons would last beyond the moment, and one clear answer was flexibility. Online learning is not the same as being in person, but we learned we could deliver a rigorous, mission- aligned online experience. As a result, our board invested resources to build and grow Spartans Around in a way that matches our academic standards.

This year, we have roughly 55 students enrolled. More than half are full-time online, and others combine online classes with on-campus coursework. For some, it supports intensive commitments, including athletics. For others, it provides an option that better fits family schedules or travel.

As we grow, we are refining the model, especially around engagement and connection. Looking ahead, I see digital learning as a tool that expands options, not as a replacement for the relationships and community that make education meaningful.

How do partnerships with universities and other organizations benefit students and support the school’s strategy?
Partnerships expand what we can offer beyond the limits of our footprint. We are about 1,405 students on a 22-acre campus, and we are landlocked, so relationships help us provide the experience families expect.

For example, our partnership with Barry University allows us to use athletic facilities we do not have on campus, supporting sports like baseball and softball. Another key partnership is with the University of Miami, which supports faculty development. Teachers can participate in graduate-level programs that are heavily subsidized. For those who remain at the school for several years, the school covers the full cost of the graduate program, and no tuition repayment is required.

For me, investing in people is essential. You can have great facilities and a great curriculum, but if you do not have great teachers bringing it to life, you do not have a great school. Our board has been strongly supportive of workforce investment, including compensation, benefits, and growth opportunities, because strong schools are built on strong adults.

We are also preparing to launch a new strategic plan, and partnerships are one of its pillars. We want to deepen relationships beyond education, so students have more relevant, real-world experiences and access to people doing the work in the community. When learning connects to real settings and real problems, it sticks.

How do global programs like Gateway prepare students as global citizens?
Gateway is one of our signature programs. Its cornerstone is a four-week summer immersion experience designed in-house. Students travel with our teachers, take classes in the mornings, and learn about the country they are in through history, policy, and cultural study, paired with local experiences.

Students receive academic credit, and the program connects to our global studies diploma endorsement. That pathway includes a Gateway experience, additional language study, selected courses, and a senior presentation based on student research. The topics vary widely, but the common thread is students learning to make connections across cultures and communicate what they have learned with confidence.

We define global citizenship intentionally across pre-K to 12. The progression begins with understanding the self, then community, then the broader forces that shape who we are, and ultimately, how students can make their world better. Gateway is one visible part of a much longer developmental goal.

What leadership principles guide you as president, and how do you ensure the school remains responsive to students, families, and faculty?
I try to keep leadership grounded in a few priorities: leave the school better than I found it, remember the work is not about me, and do the right thing even when decisions are hard.

Trust also comes from consistency. A mentor told me, do what you say you are going to do. If you cannot, go back and say so. In education, credibility matters because families and faculty rely on it.

At the end of the day, my job is two things: advance the mission of the school and take care of the adults on campus so they can take care of the kids. Advancing the mission means staying centered on students and holding high standards for every student, every day. Taking care of adults means clarity, accountability, and support, including competitive compensation, strong benefits, and professional growth.

We also work hard to maintain joy on campus. If the adults do not feel supported and energized, students feel that immediately.

What excites you most about Miami Country Day’s future and priorities over the next few years?
We are fortunate to be in a growth market like Miami, and strong enrollment gives us the ability to plan and invest. We recently opened a new athletic facility, and we will break ground on a new upper school building that will expand learning space and student experience for years to come.

Our current high school was built when we were much smaller, and the ways students learn have shifted alongside technology and the world they are preparing to enter. As we expand, we are focused on creating space that matches our academic ambition and supports the full student experience.

Academically, our program continues to broaden. High school students have more than one hundred elective choices, which helps them discover interests and build real expertise. When students can pursue a passion deeply, with guidance from teachers and access to outside mentorship, it can shape their trajectory in meaningful ways.

My priorities include launching and executing our strategic plan, deepening partnerships, continuing to invest in faculty strength, and ensuring growth stays aligned with our culture and mission.
