Wealth management is an ongoing, ever-evolving service for our private clients, which include domestic and international high-net-worth individuals, family-owned businesses, trusts and trustees, personal investment vehicles, other closely held business entities, and family offices. The complex problems confronting individual clients involve local, federal and international tax, estate planning, trust and estate administration, and litigation and alternative dispute resolution laws, rules and regulations. We focus on creating and implementing an integrated structure that will accomplish the client’s business and personal objectives in a tax-efficient and predictable manner, with sufficient flexibility to address unanticipated change. High-net-worth individuals and their family offices turn to us for unique, holistic solutions that respond to their wealth, business and estate planning needs and to their particular wishes for family governance and succession.
