• Deep technical mastery of federal transfer tax law, trust and estate administration, and advanced wealth transfer planning techniques.
• Proven ability to design and implement sophisticated multi-generational estate plans that address the full complexity of a UHNW family's balance sheet — across entities, jurisdictions, and family dynamics.
