Ross Anderson and Stephan Collier established Anderson/ Collier Architects in 2002. Anderson/ Collier specialize in high-end residential and light commercial architectural design. They have worked on projects in Washington, California, Idaho, Alaska, Hawaii and Mexico.

Managing partners, Ross Anderson and Stephan Collier, were brought together by similar styles, design interests, and backgrounds. Anderson’s small design build firm, started in the 1980s, was expanding and needed to increase staff and ideally incorporate a business partner. Stephan Collier had been working for Anderson, Koch and Smith since the late 1980s and was looking to start his own design firm.  The partnership continues to grow.
