In 2000, Scottish-born conductor and organist Joseph Cullen was appointed director of The Academy of St. Martin-in-the-Fields Chorus. Since then, the amateur choir, which ranges in size from sixteen to sixty and whose members come from all walks of life, has not only maintained its preeminent reputation but has increased its versatility still further, covering new repertoire and augmenting its a cappella appearances.

In 2001, Cullen also became director of the London Symphony Chorus. He has appeared as a guest chorusmaster and conductor with the BBC Symphony and BBC Concert orchestras, the BBC Symphony Chorus, the Philharmonia Chorus, and the BBC Singers.
