“It is always an absolute pleasure to work with William. His work on HAMLET was vital in taking three performers from vastly different areas of expertise, and bringing them all together vocally; pushing and supporting equal measure. It’s not always easy juggling the demands of verse speaking, accent and voice work, but William guides his companies with technical expertise and, even more vitally, respect for the rest of the process. Everyone leaves his sessions empowered.”

Simon Evans

“Thank you so much for your truly creative sessions” – Linda Bassett in Nilo Cruz’s Hortensia and the Museum of Dreams at the Finborough.



“Working with William is a joy. He immediately grasps the direction of the work and feeds into it so exactly that actors feel they are on a path that is going in the right direction. All my actors loved William, responding to his breadth of experience, his intelligence and his sensitivity. He was able to inspire each actor with texts which were in the main unfamiliar to them.” Kristine Landon-Smith, director/lecturer/writer, Sydney

“William ran a series of voice workshops for myself and several other performers at The Actor’s Centre – one of the venues where he works. His insight, experience and intelligence made the afternoon incredibly valuable as well as enjoyable. He is vastly experienced and has worked with some of the best voice coaches in the business. I’d recommend him highly. ” Finlay Robertson

“William was and is one of the best voice tutors I’ve ever had in my acting career. He knows his craft and he is very friendly, imaginative and an expert. My year was blessed with his presence and his humor and the things I have learned from him are still with me.”  Alexander Logothetis (Actor/Producer, Athens )

“To this day I am reaping the benefits of having worked with you” – Karim Saleh, shown here in  Le Mariage at the Arcola for which William Trotter helped Karim to adapt to stage after work in film. “You showed me that strength has to come from a place of freedom.  Working with you changed how I see life and acting in general.” Karim Saleh

“You coached me for the audition and for the shoot of David is Dying. We did voice and speech coaching, and script and character analysis. This was most beneficial, and I was awarded ‘Best Supporting Actress’ for the role at the International New Wave Film Festival in L.A.” Brigitte Millar
