Daniel’s practice includes individuals, families, and closely held businesses that have contacts in California, the United States, and the world beyond. He advises clients on all of the traditional tools of wealth planning, with an eye for holistic planning to minimize federal, international, state, and local taxes. Daniel uses these tools in service of clients’ desires to raise capable and responsible children, to support charitable endeavors, and to live happy and productive lives.

For domestic and international clients, he implements trust structures in appropriate jurisdictions to maximize benefits relating to their tax and family wealth planning goals.

Daniel represents the principal general partners of a number of funds, including private equity, venture capital, and hedge funds, and advises on the unique tax and other planning opportunities available to these fund managers.

Dan represents trustees, executors, and beneficiaries in the administration of trusts and estates, and litigates and settles disputes between trustees and beneficiaries. He has litigated throughout California and in the Surrogate's Court of Manhattan in New York. He has also resolved trust and probate litigation matters regarding the interpretation of instruments, defending trustees’ conduct, and interpreting tax allocation clauses, for example.
