The Team

Jean Diamond

Jean Diamond began her long career in the entertainment world as a junior in the literary department of the largest international agency of the day, MCA. Within a few months she took over the running of the repertory rights to all the catalogue of their client plays - including the very famous Dial M for Murder, which was released at this time. While at MCA she was offered the chance to be the assistant casting director for MGM Studios, who had a major studio just outside London and was later promoted to casting director. She worked with many great directors on many wonderful films including Ben Hurr, Dunkirk and Bhowani Junction etc.

After three years she was invited to join and create a new agency - London Management, with two partners and over the years this became one of the top three agencies in the country.

Seven years ago she decided to return to the boutique style, with which London Management had begun before it grew and grew, and started Diamond Management with partner Lesley Duff. 


Lesley Duff

Lesley was successful actress working in Film, TV, Theatre and Musicals, from the age of 16 until she decided to change the course of her life.

After two years with the RSC she was invited to take the Drama and Musical Theatre chair at James Madison University in Virginia USA. This sabbatical away from acting gave her a chance to reflect on the direction she wanted her career to go in.

On her return to the UK she decided to become an agent. For the next few years she worked for a number of top London Agencies. She joined London Management in 2002 where she met her now business partner Jean Diamond.
