Kristina Spaid | she/her | Design Lead & Art Direction
Kristina is an Air Force brat born in the Philippines and raised in the South. She has great discipline for working out but no self-control when it comes to cheese fries or French pastry.
She likes her design concepts and files to be tidy but prefers her brainstorming sessions to be a hot mess. She loves learning new things, traveling to new places, cooking new dishes, and trying new experiences—except for durian, which she has tried but can't stand.
With 14 years of experience as an art director, Kristina still loves being a creative. Her portfolio can be viewed at www.kristinaspaid.com .
