Biography
Marie Gleeson is an inspirational leadership and resilience speaker who brings to life the lessons learned from a twenty-year career at sea with the Irish Navy. Rising from cadet to Commanding Officer of the LE AOIFE, Marie’s story is one of courage, composure and commitment under pressure.
During her service, she operated in some of the world’s harshest environments, leading crews through high-risk missions, from international drug interdictions to humanitarian operations and crisis response. She has faced moments of intense challenge, including the tragic loss of a colleague at sea, experiences which forged her deep understanding of what it truly means to lead with purpose, resilience and compassion.
As one of the first female officers in the Irish Navy, Marie has consistently broken barriers and redefined what leadership looks like in male-dominated fields. Her authenticity, humour and grounded storytelling style engage audiences from boardrooms to conferences, connecting across industries with a message that is both powerful and profoundly human.
After leaving active service, Marie founded NavMar Leadership, a consultancy dedicated to helping organisations and individuals develop high-performing teams and sustainable leadership cultures. She now works with a wide range of clients — including Microsoft, Kerry Group, the Institute of Directors, Northern Trust, and the Irish Primary Principals’ Network — delivering transformative keynotes and leadership development programmes.
A graduate of the Smurfit Business School Postgraduate Programme in Corporate Governance, Marie also serves on the Boards of Bord Iascaigh Mhara and the Organisation of National Ex-Service Personnel (ONE), contributing her expertise in governance, risk and leadership culture at the top.
Whether addressing the Pendulum Summit, guiding senior executives, or inspiring school leaders, Marie’s presentations blend military precision with warmth and relatability. Her sessions leave audiences energised, reflective and equipped with practical strategies for leading through uncertainty — making her one of Ireland’s most compelling voices on leadership, resilience and human performance.
