Greet became a producer and theatre manager in his own right in 1894, as licensee of the Avenue Theatre, starting successfully with the long-running "Dandy Dick Whittington" by George R. Sims and Ivan Caryll, "The Lady Slavey" (1894) and a popular comedy by F. C. Burnand, "Mrs Ponderbury's Past" (later billed as "Mrs Ponderbury"), directed by and starring Charles Hawtrey. In 1896, Greet gave up the licence at the Avenue and moved to the Lyric, where he presented the long-running "The Sign of the Cross" by Wilson Barrett, also producing an American tour of the play. He followed that success with another, "Dandy Dan the Lifeguardsman" by Basil Hood and Walter Slaughter, starring Arthur Roberts and W. H. Denny. Greet sat on the Board of Directors of The Lyceum Theatre Ltd. from 1899 until 1902.
