Jones Walker, a 360-lawyer firm founded in New Orleans, has formed a “strategic alliance” with the D.C. lobbyists at TCH Group. The two will remain separate entities while serving shared clients, Jones Walker said in announcing the deal this week.

Jones Walker services clients in the southeast and is looking to expand on its Louisianan roots. R. Christian Johnsen, leader of the firm’s federal government relations practice in D.C., noted that his firm doesn’t have a presence in South Carolina, where TCH represents the city of Charleston.
