GEMMA HAMILTON – Head Agent/Managing Director

Gemma is an ex-professional actress/singer who trained at The Arts Educational Schools and worked professionally in West End, touring productions, TV & commercials. During her 15 years of performing she had the pleasure of working with directors such as Trevor Nunn, Gillian Lynne, John Doyle and Anthony Van Laast. It was a natural progression to change her career path to personal management in 2005 after she assisted Simon Beresford at Dalzell & Beresford. Eventually in 2009 LHA was launched and since then the agency has flourished and gained a significant reputation within the industry. Having experienced the life of a performer and with over 12 years agent experience, this has been an invaluable contribution to clients. She works with enthusiasm to develop & nurture careers and in addition occasionally sings to her clients to remind them she used to be on the stage - relishing any opportunity to help with song choice.


Adam has a wealth of experience as an agent, casting director and performer. He trained at Laine Theatre Arts and performed professionally until he changed his path over five years ago. Adam continues to work successfully as a freelance Casting Director and has worked on numerous productions including; for Paul Taylor-Mills Ltd, Amy Anzel Productions & Regan De Wynter Productions for The Union Theatre where he casts regularly.

MARIETTA BOUTROS – Assistant/Accounts Manager

Marietta has a background in accountancy and is particular good with numerics (useful). Having been with LHA now for 4 years, she brings to the office calm and serenity and often says ‘Bless you’ when one hasn’t even sneezed. Etta is an important member to the team, advising clients on any financial & tax queries.
