about us
Leonium
My name is Leon Keller, born and raised in Switzerland. I bring over 10 years of experience in the world of investments, with the past 5 years dedicated to crafting smart, tailored investment solutions for Family Offices and high-net-worth individuals.
I specialize in delivering a discreet, personalized, and strategic advisory experience, designed to align with each client’s unique goals, values, and risk profile. My Swiss background shapes my approach—precise, thoughtful, and always grounded in trust and integrity.
I work closely with clients to navigate complex financial landscapes, offering access to distinctive opportunities across global markets, private investments, and long-term wealth planning
