Katie Martinez

Katie is committed to designing interiors that are equally beautiful, functional, and livable. She approaches projects with order, organization, and a focused process that turns out effortless spaces with an undone feel. A medium for each client’s style, Katie draws out their unique preferences through collaboration and dialogue over the life of each project.

An East Coast native, Katie cut her teeth in New York at André Balazs and Rockwell Group before heeding the call of the West and moving to San Francisco. There, she worked at Wiseman Group and Nicole Hollis before establishing Katie Martinez Design in 2013. Katie has a BFA in Art and Art History from Dartmouth College and an Interior Design degree from Parsons School of Design. She lives in Ipswich, MA with her husband and two daughters and frequently travels to KMD’s San Francisco office for West Coast projects.

Kelly Berger
Senior Designer

Kelly’s love of art, architecture and interiors can be traced back to her immersion in all three at Des Moines Art Center where she took classes as a young girl. After class, she roamed free range for hours in the museum’s distinct wings designed by Richard Meier, I. M. Pei, Eliel Saarinen. Kelly studied art at the University of Iowa where she earned a BFA in Painting and Drawing and went on to earn a Master of Architecture at University of Pennsylvania. Before joining KMD, she worked at San Francisco architecture firms EHDD and Mark Cavagnero Associates. Kelly’s interest gravitated to interiors as she realized that true equilibrium results from a balance between architecture, light, color, texture, and furniture. She lives in Oakland with her husband and two cats.

Stefanie Sillin

Despite her affinity for beauty, building and craft, Stefanie was initially swept into tech after graduating from San Francisco State with a Bachelor’s in Communications. On her weekends, wandering through inspiring places including The Art Institute of Chicago stoked her interest in light, space, and design. Eventually, she left her tech job and returned to the Bay Area where she studied Interior and Architectural Design at Berkeley. As a designer at KMD, she understands that there is more to interiors than meets the eye; to evoke a mood or feeling, she begins with the functions of a space and then asks, how would you like to feel here? To cleanse her mental palette, she begins each morning at her home in Marin county with meditation and palo santo, and then kicks into gear with coffee.
