In the words of Jessica Hische:
Sarah Parmenter is a web-centric wonder-woman and owner of You Know Who Design, a multi-disciplinary studio that specializes in interface design for iOS.
When not spending hours upon hours in her Essex studio making pixel-perfect creations, she can be found on stages around the world inspiring and educating others.
Aside from her work for clients like Blackberry and the National Breast Cancer Foundation, she also co-hosts the Happy Monday podcast and always has another fun project in the works.
In 2011 she was named .net magazine’s ‘Designer of the Year’, she’s never afraid to point out English-isms, and is the girliest “dude-girl” I know.
