Ellen joined Fragomen as a Partner in 2001 when the law firm she previously co-founded was merged with Fragomen’s practice. She began her legal career serving as a corporate lawyer for seven years and headed the Canadian Practice Group for a Buffalo, New York firm of more than 100 lawyers. Thereafter, she co-founded a law firm in Buffalo that primarily advised Canadians doing business in the United States in connection with corporate, tax and business immigration law matters.
Ellen concentrated her practice on Canadians entering the United States under the provisions of the North American Free Trade Agreement (NAFTA). Following the merger of her practice with Fragomen, Ellen assisted with the opening of our firm’s first office outside of the United States in Brussels, Belgium.
She practices exclusively in the area of U.S. business immigration law with an emphasis on small and medium-sized corporations. Ellen works with a wide range of industries and highly-skilled or high net worth individuals, primarily citizens of Canada or European countries.
