In an interview with NPR’s Susan Stamberg, Saoirse Ronan described Sam as “worth [his] weight in gold” (link).
"I really enjoyed working with Sam on what was a complicated hybrid accent. The sessions were relaxed and fun and Sam‘s thorough approach and keen ear were hugely reassuring. He also recorded scenes for me to listen to between our sessions which was extremely helpful.” - Simon Pegg, Nandor Fodor and the Talking Mongoose
“The absolute best, most reliable and enjoyable dialect coach I have ever worked with. Immense ability coupled with clarity of communication and as a bonus, a lovely human being. I only work with other coaches when Sam is busy.” - Alex Sharp, The Hustle
"I have been working with Sam for nearly five years now and he is without a doubt one of the best dialect coaches I have encountered. Incredibly precise, encouraging and a terrific asset to any actor who wants to improve their vocal range and experiment with different dialects. He has always gone above and beyond to ensure I feel confident and prepared and has become an invaluable part of my process as an actor.” - Janet Montgomery, New Amsterdam
