With over a decade of experience guiding affluent families through the complexities of wealth management, Guillaume is known for delivering advice that is both highly personalized and strategically sound. His approach is grounded in trust, discretion, and a deep understanding of the financial realities facing entrepreneurs, executives, and professionals.

Before joining BMO Private Wealth, Guillaume traveled extensively throughout Asia and Africa, advising successful high-net-worth and ultra-high-net-worth individuals on sophisticated investment strategies designed to preserve and grow multigenerational wealth. Additionally, his background as a commercial banker sharpened his ability to assess financial opportunities and risks across a wide range of sectors — giving him a unique edge when structuring tailored solutions.

Outside of work, Guillaume is driven by a deep intellectual curiosity, with a passion for geopolitics and a constant desire to expand his understanding of the world. He has an appetite for “type 2 fun” — the kind of challenges that push limits and leave lasting stories. Above all, he values relationships — both personal and professional — and sees trust as the cornerstone of every successful partnership.

With over 15 years of experience working with high-net-worth individuals around the world, Simon is recognized for his integrity, thoughtful guidance, and ability to simplify complex financial decisions. His client relationships are built on trust, discretion, and a commitment to delivering a seamless wealth management experience.

Simon works closely with entrepreneurs, senior executives, and professionals, offering tailored strategies that reflect both their ambitions and their realities. His multidisciplinary background and global exposure — from Africa and the Middle East to Asia and Europe — have shaped his deep understanding of international markets, cross-border wealth considerations, and the evolving needs of global families.

Beyond his professional expertise, Simon is a dedicated family man who finds balance in nature and draws inspiration from travel. Whether hiking through the woods or discovering a new culture, he believes that time spent away from the noise is key to staying grounded and focused on what truly matters — for himself and for his clients.
