Duncan has broad experience handling complex civil litigation matters.  He has achieved outstanding results for his clients through a combination of zealous advocacy and creative problem-solving and counseling.  He is well-versed in all phases of litigation, and has argued multiple cases before the Washington State Supreme Court.

Before joining Savitt Bruce & Willey, Duncan was a partner at Riddell Williams and a principal at Rafel Manville, both in Seattle.  He is a cooperating attorney with the ACLU, and has represented the Fremont Sunday Market and many other clients pro bono.  He is the Immediate Past President of the Board of Directors of On the Boards, a contemporary performing arts organization.  Duncan is a graduate, cum laude, of the University of Chicago Law School.

When not in the office, Duncan spends as much time he can with his wife (also a lawyer) and their two lovely little girls.  His other interests include cycling, hiking, and taking many, many photos, some of which are in focus.
