Over her career, she directed multibillion-dollar budgets, drove audit readiness, and led efforts to modernize financial systems and strengthen fiscal integrity. Hunter’s expertise in both strategic planning and hands-on execution has been widely recognized across the federal CFO community. At MSI, she will lead the Finance practice, focusing on helping agencies modernize financial operations, enhance stewardship, and comply with evolving statutory and OMB requirements.
