Duet exists to release ease, effectiveness, and harmony into the ways we work together.

We start by grounding in your purpose. Then we facilitate the use of dynamic and adaptive structures and processes that are best suited to help you express it.

Successful collaboration between people in different teams or organizations is our aim and specialty.

Our emerging offerings include professional services, workshops, training, coaching, and backbone support for collective impact work.

Duet is based and operates on the unceded ancestral land of the first people of Seattle, the Duwamish. Though the city named for the Duwamish leader Chief Seattle thrives, the Tribe has yet to be justly compensated for their land, resources, and livelihood. Duet is a monthly supporter of Real Rent Duwamish.
