Meet Your Teacher
HI, I’M ROSIE!
I'm the heart and hands behind Rosie's Casting Studio, a successful lifecasting business based in New Zealand. My journey into the world of casting began when my son was born prematurely. I had his little hand and foot cast, and they became my most treasured keepsakes!
Initially, I wanted to learn casting just for a hobby. So I began learning…and ended up turning into a business! The success of Rosie's Casting Studio pushed me to take things a step further…so I launched 'Rosie's Casting Academy' to share my knowledge and skills, guiding aspiring lifecasters on their journey.
I can't wait to be a part of your story! Here's to creating and growing together!
