    John Foster Fairfax has spent more than three decades working where law, government, and public service meet. His career did not follow shortcuts or headlines. Instead, it followed a steady path of responsibility, long-term thinking, and service. From local government to one of the largest public school systems in the country, John Foster has focused on building systems that last.

    “I never set out to chase titles,” he says. “I wanted work that mattered and institutions that served people well.”

    That mindset shows up across his career.

    John Foster: Building Public Trust Through Law

    Early Life Shaped by Service

    Foster grew up as a military child. He was born at Camp Pendleton and lived on Marine Corps bases in California, Hawaii, and Virginia. His father, James F. Foster, was a career Marine officer and a decorated combat leader in Vietnam who retired as a Colonel.

    Living on bases shaped how John Foster saw leadership. “In the military, you learn early that the mission is bigger than you,” he says. “You also learn that systems only work when people trust each other.”

    His mother, Marian K. Foster, was an immigrant from England who became a U.S. citizen in her twenties. She worked as a paralegal for Virginia law firms for 40 years. She was also a World War II refugee who survived the London Blitz as a child.

    “My mother showed me resilience in a quiet way,” John Foster says. “She believed in doing your job well, every day, even when no one is watching.”

    Education and Early Legal Career

    John Foster earned a BA in History and Foreign Affairs from the University of Virginia in 1989. He stayed at UVA for law school, earning his JD in 1992. The combination shaped his interest in public institutions and how law supports them.

    “I was drawn to how decisions made today affect people years later,” he says. “History teaches you that.”

    He began his career as a Senior Attorney at Buonassissi Henning Campbell and Moffet, where he spent seven years. The work gave him a strong legal foundation and exposure to complex cases.

    “That period taught me how to think clearly under pressure,” John Foster says. “It also taught me that preparation is everything.”

    Moving Into Public Service Law

    In 1999, John Foster moved into government work as an Assistant County Attorney with Fairfax County. He stayed for nearly a decade. The role deepened his focus on public accountability and long-term planning.

    “When you work for a county, your client is the public,” he explains. “You have to balance legal risk, public trust, and practical outcomes.”

    In 2008, he became City Attorney for the City of Falls Church. There, he worked closely with city leadership during a time of growth and change.

    “You see decisions up close,” John Foster says. “Small choices can have big ripple effects in a community.”

    General Counsel for Fairfax County Public Schools

    In 2013, John Foster stepped into his current role as General Counsel for Fairfax County Public Schools. The system is one of the largest in the nation. The job requires legal clarity, steady judgment, and collaboration across many stakeholders.

    “Education law is about people,” he says. “Students, teachers, families. You can’t lose sight of that.”

    John Foster is known for translating complex legal issues into clear guidance. He focuses on helping leaders make informed decisions rather than reacting to problems after the fact.

    “My job is to help good ideas survive real-world pressure,” he says.

    Leadership, Recognition, and Professional Service

    John Foster is AV-rated (preeminent) by Martindale-Hubbell, a recognition based on peer review. He also serves on the Virginia State Bar Council for the 19th Judicial Circuit, a role he will hold through 2028.

    “These roles are about stewardship,” he says. “You’re helping set standards for the profession.”

    Outside of work, John Foster is a long-distance cyclist. He spends time riding gravel and mountain bikes through rural and remote areas.

    “Cycling clears my head,” he says. “Long rides teach patience and endurance. Those lessons carry over to work.”

    He has also served as past president of Christ Lutheran Church, reflecting his long-standing commitment to community involvement.

    A Career Built on Consistency

    Looking back, John Foster sees a common thread. Each role built on the last. Each step added responsibility without losing sight of service.

    “I believe in showing up prepared and staying steady,” he says. “That’s how trust is built over time.”

    His career shows how big ideas do not always arrive with noise. Sometimes, they arrive through consistency, discipline, and a willingness to serve institutions that matter.

    “That kind of work isn’t flashy,” John Foster says. “But it’s important. And it lasts.”
