Tremblay brings more than 20 years of leadership experience working with ultra-high-net-worth families and large single-family offices
NEW YORK – June 8, 2026 – Cresset announced today that it has appointed Mark Tremblay as Executive Managing Director, Head of Family Office Services. Tremblay brings more than 20 years of leadership experience in the wealth management industry with significant experience in investments, operations, and client service delivery. He will be based out of Cresset’s New York office and will join the firm’s Management Committee.
Prior to joining Cresset, Tremblay was Regional Director and Head of Family Office Management at Bessemer Trust, where he led all client service delivery for the Midwest region. Earlier in his career, he spent 12 years as a strategy consultant with the Monitor Group and was responsible for large-scale corporate transformations. Tremblay has an extensive background in delivering tailored fiduciary, tax, trust, and estate services for ultra-high-net-worth families and large single-family offices.
“Mark has spent more than two decades working alongside highly sophisticated families through liquidity events, generational transitions, and the ongoing challenge of managing multiple moving parts at once. That experience brings a level of judgment and perspective that is earned over time. His leadership strengthens our capabilities and accelerates how we deliver for clients whose needs continue to grow in complexity and scope,” said Cresset CEO Susie Cranston.
“I have spent my career working with families navigating complex, long-term decisions, and it is clear that what they value most is thoughtful coordination and true alignment. Cresset has built a platform and a culture that reflects that reality. I am excited to contribute to a team that is focused on delivering a more integrated and forward-looking approach,” Tremblay added.
Tremblay earned an MBA from Harvard Business School, an MLitt from the University of St. Andrews in Scotland, and a Bachelor of Arts, magna cum laude, from Harvard University. He lives in New York City with his wife and five children.
