Rosie began her career working with Alan Partridge and Vic and Bob.

During this time, she worked extensively with comedy and drama scripts and collaborated with a wide range of writers, producers and talent.
“Rosie is pretty uniquely placed in the comedy telly fraternity. Lovely to work with, a can-do approach to anything big or small AND she can write and direct. In fact is there anything she can’t do? I’ve changed my mind, she’s annoyingly talented and needs to be stopped."
-Lucy Lumsden, Yellow Door Productions
“Rosie is next level. She is a kind and considerate director, who respects everyone’s roles, and collaborates constantly with producers, creators and writers. She is talented, passionate and deserves all the great things that are about to happen to her career. I would personally work with her again on any project.”
-Gina Lyons, Award Winning Producer Dreaming Whilst Black and In My Skin
