Our Founding Story

It all began with a story...

In the early 1970s, two families — bound by deep friendship, shared values, and a vision for the future — came together with a simple yet powerful idea:
that wealth, when guided by purpose, can be a force for enduring good.

Their decision to unite efforts marked the birth of a new kind of family office — one not only focused on preserving and growing assets, but also on creating positive impact in the world.

From this close partnership grew a philosophy of trust, responsibility, and long-term thinking that continues to guide us today. Over time, other like-minded families joined the circle, and what began as a quiet collaboration became a respected and influential firm — serving multiple generations and supporting initiatives that touch lives across continents.

Our legacy began with friendship. It continues with purpose
