Rianne Dritty
Every career tells a story. Mine began in finance and control, where I built a strong analytical foundation. Over time, I moved beyond managing numbers towards shaping strategy and governance. Having worked across corporate, public, and educational sectors, I bring a broad perspective that enables me to connect financial insight with organisational vision.
Since 2021, I have worked as an interim professional and entrepreneur, partnering with boards and senior leadership to strengthen financial governance, execute strategy and drive organisational transformation. I am valued for bringing energy, clarity, and decisiveness to complex issues, while ensuring that choices are grounded in both data and people. I do not just provide figures: I help organisations make strategic decisions with confidence.
Lifelong learning is part of who I am. Over the years, I have completed the post-HBO Registered Financial Controller® programme (2015) and a master’s degree in Business Process Management & IT (2020). I am currently pursuing the Executive Master of Finance & Control at Maastricht University, which I will complete in December 2025. In addition, I am a certified Supervisor (Board of Supervisors). This combination of expertise reflects my ambition to contribute at the highest level of governance and control.
My style can best be described as sharp in analysis, strategic in outlook, and people-oriented in execution. I enjoy working in environments where vision and practice must be aligned, and where sustainable results depend on both strong governance and engaged teams. Outside of work, I recharge through travelling, reading, and enjoying good food: because balance is the foundation for lasting impact.
