For Richard L. Adams, leaving Hunton & Williams last year to join Vinson & Elkins as a partner in Dallas was a smooth transition because he had spent many months working daily with V&E lawyers as co-counsel for a group of clients acquiring TXU Corp.

Three partners and three associates from Hunton’s utilities regulatory group joined Adams in the move. But leaving the Dallas office of the Richmond, Va.-based firm was difficult, he says. “I had worked with several people at Hunton for three decades,” Adams says. “So it was hard to tell some of the people that I and the group were leaving. But at the same time there was no question in my mind that it was the right decision. So in a sense it was difficult, and in a sense it was easy.”
