Grayson Holden
Designer + Project Manager

Since joining envelope A+D, Grayson has attempted to supplement this understanding through bits of gloss afforded by technology. Alternately, Grayson hones his competitive edge by training for and playing quad rugby. Grayson took several top prizes upon earning his Bachelor’s of Architecture from the California College of the Arts, including the Henry J. Adams merit award.

Lizzie Wallack
Designer + Project Manager

Lizzie received her undergraduate degree in furniture design at the California College of Arts and Crafts in San Francisco. After a brief stint as a photo stylist back in Boston, she returned to (the newly re-branded) California College of Arts to explore her curiosities concerning the built environment, people, and space. Her Masters of Architecture included several competitive distinctions: Jury Prizes, Design Excellence Awards, and the highly regarded Thesis Prize. She has taught at CCA and continues to be active in the CCA community. Lizzie remains hungry to envision the future of design while bookmarking images of late ‘60s-early ‘70s muscle cars, which one day she will white, of course.
