Charles Forbes leaves the Regent on Broadway after 20 years leading the theatre.
On Friday, Charles was farewelled in the theatre at a function attended by invited guests.
Acting general manager David Walsh said Charles was a very likeable chap.
"He has a lot of theatre knowledge and has done all the hard yards."
Charles started at the Regent in 1998 as staff technician, and, in 2000, stepped into the role of general manager.
