Design for what comes next.

If humans have a future, it’s a sustainable one. The products that get us there will be drawn from resilient supply chains, regenerative ecosystems and built by the teams who know how to design for participation - not just consumption.

I help product and sustainability teams design for the post-disposable economy. Hands-on workshops, custom field guides, and bespoke advisory. Design research approach developed at the Ellen MacArthur Foundation and Royal College of Art.

Ethos

Constraints are lenses, not limits.

Most consulting engagements end at the slide deck. Mine ends at something - a prototype, a workshop kit, a field guide a team can actually use. Informed by fifteen years of industrial design, three inside the Ellen MacArthur Foundation, and a working theory that big problems yield to small, testable questions.

FOUR WAYS TO ENGAGE

A large conference room filled with people seated at tables, engaging in discussions and activities during a workshop or seminar. There is a whiteboard and charts on the walls.

Activation
Workshops, sprints, and capability programs that build circular thinking into how teams operate.

Research
Original analysis, interactive data, and The Riparian - observations on the systems shaping circularity.

I'm a circular economy strategist and industrial designer based in San Diego. Most recently three years inside the Ellen MacArthur Foundation, working alongside the world's largest organizations on implementing circular strategies. Before that: fifteen years across toy design, escape rooms, public installations, and innovation consulting for the Fortune 100.
