We guide our clients through all legal and tax aspects of their wealth planning, management and succession. The firm has two primary focuses: (1) international families and private investors with connections to the United States, owning investment assets or business interests and with family members living in or moving to the United States; and (2) domestic families needing succession planning for intergenerational wealth.

In addition, the firm represents fiduciaries and beneficiaries in the administration of trusts, estates and other United States entities. Members of the firm frequently serve in trusted fiduciary positions for our clients, whether as trustees, agents, limited liability company managers or corporate officers and directors.

Our principal attorneys are Peter Rosenberg and David Elwell.
