Founder & CEO
Guillaume Decalf
Guillaume Decalf has spent more than twenty years advising first organizations on their processes, then individuals on their wealth. He began his career in France as a consultant in operational strategy, before spending several years in the United States, where he deepened his understanding of the financial decisions facing globally minded families.
Over time, his focus shifted from efficiency to legacy — from solving problems to preserving what matters most. What remained constant is his commitment to structure, clarity, and intention.
At Lengrand & Henri, Guillaume serves as the firm’s strategic architect. Known for his discretion, precision, and integrity, he guides the firm’s philosophy and ensures every solution reflects the values, goals, and complexity of the families it serves.
Financial Planner & Investment Advisor
Smara Savoy
Born in Switzerland’s French-speaking region, Smara built the early part of her career with Nestlé before relocating to the United States in 2013. Having lived and worked across multiple states, she experienced firsthand the challenges of navigating finances between Europe and America, a perspective that would later define her professional calling.
After a successful career in Human Resources and Talent Acquisition, Smara redirected her expertise toward her true vocation: helping families bring clarity to financial complexity. She became a Financial Coach, then earned her Series 65 license, joining We Financial in 2024 as a Financial Planner and Investment Advisor.
Today at Lengrand & Henri, Smara combines her cross-cultural insight with a disciplined approach to wealth planning. With discretion and empathy, she helps families manage the intricacies of cross-border wealth, ensuring their legacy is preserved with clarity and confidence.
