Who we are
Marshall Van Zandt is a family-owned accounting and financial advisory firm built to bring clarity, structure, and reliable support to organizations at every stage of growth.
We specialize in the work that often falls between traditional bookkeeping and a full-time financial executive: untangling complex financials, cleaning up accounting systems, strengthening internal processes, supporting nonprofit and fund accounting, and providing fractional controller and CFO leadership.
Behind that strategic work is dependable day-to-day accounting and operational support. This allows us to meet clients where they are, whether they need help solving a specific financial problem, completing a special project, or building an ongoing accounting function that can grow with them.
As a family business, MVZ is intentionally built to scale while remaining personal. Our goal is not simply to keep the books. It is to create financial systems that give business owners, nonprofit leaders, and boards the clarity and confidence to make better decisions.
Melissa Marshall | Co-Founder & Fractional Controller
Melissa leads MVZ’s accounting, controller, and financial advisory work, bringing more than 15 years of experience across public accounting, nonprofit finance, real estate operations, and privately held organizations.
Her specialty is stepping into financial environments that have become complicated, unclear, or have simply outgrown their existing systems and bringing them back under control. Her work spans financial cleanup and reconstruction, nonprofit and fund accounting, internal controls, audit readiness, financial reporting, budgeting and forecasting, systems implementation, and fractional controller and CFO leadership.
Before expanding MVZ, Melissa spent more than six years as Controller of Arrowhead Lake Association, where she oversaw multimillion-dollar operations, strengthened financial infrastructure and internal controls, managed audits and board reporting, and led major financial process improvements.
Today, she is happiest somewhere between the numbers and the puzzle: finding what isn’t working, understanding why, and building a financial system leadership can actually use.
Kyle Van Zandt | Co-Founder & Operations
Kyle is co-founder of Marshall Van Zandt and an integral part of the firm’s operations. For years, he has worked alongside Melissa supporting bookkeeping, data entry, administrative processes, and the day-to-day execution behind client engagements.
His operational support allows Melissa to concentrate her time where she creates the greatest value for clients: financial analysis, complex cleanup, systems improvement, controller oversight, and strategic guidance.
Kyle’s professional background spans logistics, property operations, maintenance, facilities, and hands-on project work. That experience gives MVZ a practical understanding of the operational realities behind the numbers and additional perspective when client needs extend beyond the accounting department.
Together, Melissa and Kyle have built MVZ around complementary strengths: the strategic work and the work that keeps the strategy moving.
Built to Grow With Our Clients
MVZ was designed as a family business with room to grow. Our model combines experienced financial leadership with dependable accounting and operational support, allowing us to build the right level of service around each engagement.
For some clients, that means focused help with a cleanup, audit, system implementation, or special project. For others, it means an ongoing relationship combining bookkeeping and day-to-day accounting with controller or CFO-level oversight.
As our clients’ needs grow, so can the team supporting them, while financial leadership and accountability remain closely held within MVZ.
