Ashurst strengthens New York tax team

People Thumbnail

Ashurst has made Jeffrey Koppele and Sharon Kim partners at the US tax practice. This expands the New York tax practice to 21 lawyers, including five partners.

With almost 30 years of experience, Koppele joins the firm after seven years as a partner at Dentons. He began his career at Weil Gotshal & Manges before moving on to Latham & Watkins and Thacher Proffitt & Wood. Koppele developed a speciality in tax and derivatives, particularly for hedge funds and swap dealers. He later joined Sonnenschein Nath & Rosenthal in 2009 and stayed on after the merger with Dentons the following year.

Kim has been at Ashurst since 2009. Before joining the firm, Kim was an associate with McKee Nelson for six years. She has advised leading international financial institutions and investment houses on aspects of US federal income tax for capital market transactions, such as debt and equity.
