Months after leaving his position as chief counsel to Mayor Eric Adams, Brendan McGuire has returned to Wilmer Cutler Pickering Hale and Dorr to form a new practice with his old firm that will guide clients through the thickets of New York City’s vast bureaucracy, among other services.

McGuire left City Hall after a 20-month stint as the top attorney for Adams, advising the mayor as his administration grapples with major issues that include a massive influx of more than 100,000 migrants into a city with a “right to shelter” law and a potential federal takeover of the jail complex on Rikers Island, where inmate deaths have spiked in recent years.
