US lawyers are spreading the word about northern firms following a flying visit organised by the Cowen Group.
The group is named after its founder, Booth & Co joint senior partner Maurice Cowen.
American members of the group gave seminars to Booth & Co clients in Leeds and to those of Addleshaws Sons & Latham in Manchester.
The speakers included child abuse specialist Valerie Hoffman of Seyfarth Shaw, Fairweather & Geraldson.
The firm's Peter Eikenberry says: "We look forward to spreading the word in the US that you don't have to go to London if you want to find first class legal work in England."
Booth & Co spokeswoman Rachel Culver says: "We really appreciate them coming over. The feedback from clients has been positive."
