  • Former UK ultra-high-net-worth team from Credit Suisse to lead Zurich office

New York & Zurich, September 3, 2019 – Tiedemann Advisors, one of the largest independent U.S. investment and wealth advisors for high-net-worth families, trusts, foundations, and endowments, and Constantia Partners AG, an independent Swiss capital consultancy firm, today announced they have co-founded Tiedemann Constantia, effective immediately. Through this agreement, Tiedemann Constantia will offer a unique set of investment and wealth management services to high-net-worth individuals, families, family offices and foundations on multiple continents.

Tiedemann Constantia in Zurich will be led by Robert Weeber, founder of Constantia Partners. Joining Weeber, will be a team of specialized private bankers from Credit Suisse’s UK International Ultra-High-Net-Worth unit, Pierre Bose, CIO, and Gareth Maher, Managing Director. While at Credit Suisse, Weeber, Bose and Maher managed over $7 billion in client assets, and will look to leverage their extensive international experience and central location in Zurich to service international and multi-national clients based in the U.S.

“We are delighted to start operations with Tiedemann Constantia in Switzerland and look forward to offering a fully-fledged suite of wealth management services to our clients out of Zurich. We see the EMEA region as an important growth market offering attractive investment opportunities for our clients,” said Weeber. “Given the interconnectedness of today’s markets, we were actively seeking a U.S. partner to complement our investment offering. Today’s alliance with Tiedemann better positions us to assist our current and future clients with their multi-jurisdictional wealth management needs.”

“The opening of our Zurich office represents another milestone in our strategy to become a leading and preeminent, privately owned global wealth management firm that serves high-net-worth families and family offices across the globe,” said Michael Tiedemann, Co-Founder and CEO of Tiedemann Advisors. “The trusted relationships that Robert and the Constantia team have developed over their tenure established them as the ideal partner for growing our network across the Atlantic and for broadening our investment capabilities to seek global opportunities. As an independent, privately owned firm, we look forward to creating customized solutions for our diverse client base and develop a lasting foundation for future growth and success.”

Complementing its existing trust jurisdictions, Tiedemann Constantia will have the ability to offer clients trust services through Tiedemann Trust Company, a U.S. state-chartered trust company located in the state of Delaware. The firm aims to attract the growing number of international assets moving to the U.S. as opposed to less-regulated locations in recent years. At the same time, Tiedemann Constantia will draw from Tiedemann’s deep-rooted impact investing offering to engage with a sophisticated European client base.
