Local Architecture Firm Heightening Presence in Seattle Area

PORTLAND, OR-Sienna Architecture Co.’s commitment to the Puget Sound market is paying off, in jobs and architects. The urban design firm, based here, has been servicing Seattle-area companies for 25 years now. Indeed, the firm’s work in Washington has at times outstripped its Oregon work. It wasn’t until nine months ago, however, that CEO Gary Reddick and company decided to not only have a Downtown company apartment, but also open a small, two-person office in the nearby Maritime Building.

It’s paying off. With several new urban design wins in hand, Sienna last week brought on four well-known architects–three of them as principals–to grow its Seattle-area business even more. Joining the firm are Steve Harmon, Darryl Custer and Kirk Callison, all of whom previously held senior and principal-level positions with Mulvaney/G2.

Harmon brings 20 years experience in retail, office, commercial and mixed-use design to Sienna. Custer has 11 years of experience and specializes in high-end residential, commercial office, corporate headquarters, high-tech facilities, interior design, space planning and tenant improvement management. Callison brings 10 years of experience in commercial, retail, multi-family housing, master planning, and programming to the team.
