Established in 1986 by Doreen O’Neill, with a remit to nurture young talent in Wales, Harlequin Agency now has a global reputation for its personal management of artists by its team of dedicated staff.

Harlequin has a growing roster of singers, instrumentalists, conductors, accompanists, composers and arrangers, and an increasing number of concert productions and projects, in addition to its broadcast division, Harlequin Media.

The meteoric rise to stardom of bass-baritone Bryn Terfel continues to be instrumental in the company’s development.  Together with the independent television company, Boom Cymru, Bryn is now a co-owner of the agency.
