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.

In addition to representing foreign clients in obtaining permission to work or live in the United States, Ellen is actively involved with several international bar associations. She serves as President of the American Foreign Law Association. Ellen is a frequent speaker and author, and she represents the firm at international conferences and meetings with both governments and non-governmental organizations in connection with global business migration.

Ellen is the founder of the Pro Bono Immigration Project of the Bar Association of Erie County, which represents indigent aliens detained at the Federal Detention Facility at Batavia, New York.

Ellen speaks English and French.
