“I worked with Sierra Dann on the short film, “This Promise” Sierra was the First AD. Sierra was outstanding in every regard. She was super prepared and always early. She is a really strong communicator and bubbly with everyone on set. We had lots of extras and she organised them perfectly for us. She was a real gem on the shoot. We were utterly delighted with her and her work. I would hire Sierra again in an instant.”

Office / Publicity & Branded Content

I had the pleasure of working with Sierra on creative campaigns for Revive Active, and she was fantastic to collaborate with. Sierra brought incredible energy, creativity, and professionalism to every aspect of the project.

As a producer, she seamlessly managed everything—from shaping creative concepts to directing talent on shoot days—ensuring we got the most out of every shoot. Her approach created a fun, collaborative environment that made everyone feel at ease.

Sierra also pushed the boundaries of our creative strategy, introducing fresh ideas like educational UGC content and nostalgia-driven ad concepts that truly resonated with our audience. Her input directly contributed to strong performance and high ROAS on our ad accounts.
I would happily recommend Sierra for any creative or producer role—she would be a fantastic asset to any team.
