Ms. MacLean is a seasoned litigator with experience in federal and state court as well as arbitration. She has represented individuals and corporations in a wide variety of commercial disputes, in industries including steel, precious metals, luxury goods, energy, entertainment, technology and more.

Her practice there, in addition to the commercial disputes described above, included a significant pro bono component, primarily in the areas of immigration and family law. She has also enjoyed coaching high school students in mock trial and moot court competitions. Ms. MacLean is the author of Choosing Your Rules: Considerations When Drafting Arbitration Clauses, in 40 under 40: Upcoming Issues of International Commercial Arbitration (Carlos Gonzalez-Bueno ed.)
