Aaron has been a practicing lawyer since 2010. After law school, he was a Skadden Fellow and Staff Attorney in the Employment Law Unit of the Legal Aid Society for over three years, where he represented Chinese and other immigrants in a variety of employment and labor disputes. His legal victories were covered in publications such as the New York Times, Wall Street Journal, Newsday, New York Post, and a wide variety of Chinese language media. From 2013 to 2014, Aaron served as a law clerk to the Honorable Richard J. Sullivan of the United States District Court for the Southern District of New York.
The $474,000 court award obtained by Aaron and his colleagues at The Legal Aid Society after a jury trial in the Babi Nails Salon case (Song, et al v. 47 Old Country, Inc., et al., 09-Civ-5566 (E.D.N.Y.)) was mentioned in the New York Times article on exploitative conditions in New York's salons that brought about executive action to reform that industry.
Aaron co-counseled with the Urban Justice Center to successfully represent Chinese restaurant workers in a federal court trial in 2016.
A sexual harassment case litigated by Aaron and his colleagues at The Legal Aid Society resulted in an imposition of the largest fine in the history of the New York City Human Rights Commission against an employer. (See story in the New York Post.)
