Leslie practices in a wide range of U.S. and international tax areas. She counsels clients on advantageous business structures for tax and estate planning purposes. Leslie has a particular focus on helping high-net-worth families manage estate planning goals in multiple jurisdictions. Her practice often focuses on cross-border matters, including structuring considerations in purchasing U.S. real estate, business expansion into the United States, tax considerations in private and public offerings, and the application of the U.S. anti-deferral regimes. She also regularly counsels clients on U.S. tax compliance matters as well as the ramifications of relinquishment of U.S. citizenship or lawful permanent ("green card") status.

Leslie's clients include business owners and investors, high-net-worth individuals and privately held businesses.
