Ambitious goals, turned into real results
Led by a former Statewide Sustainability Officer with 20+ years of experience, WSS gives agencies, communities, and consulting firms the technical depth of a large practice — without the overhead of one.
Good intentions rarely survive a budget cycle
Most sustainability plans stall the same way: strong vision, thin implementation, and no one left to carry it once the consultants move on. Technical work that doesn't account for procurement rules, funding cycles, and staff capacity ends up as a report on a shelf rather than a program that runs.
Bringing in the capacity you're missing
Subcontract Support
Technical and program expertise for prime consulting firms on public-sector, corporate, and utility engagements.
Fractional & Interim Leadership
Short-term sustainability officer or program-lead capacity for agencies between hires, or scaling a new initiative.
Project-Based Advisory
Defined-scope engagements for planning, research, policy development, and grant strategy — with a clear start and finish.
Extension of Staff
Ongoing advisory support that supplements an internal sustainability team on an as-needed, month-to-month basis.

- Produced annual sustainability reports for industry associations and school districts, providing accountability and documentation of progress.
Facilitation, Guidance & Training

Dave Wortman
Dave is a former Statewide Sustainability Officer for the State of Oregon (2017–2025) and a national consultant with more than 20 years in enterprise GHG accounting, statewide procurement policy, and sustainability program management.

WSS turns technical work into well-funded projects and successful implementation — for communities, state and regional governments, the education sector, nonprofits, and companies dedicated to authentic change. The model is deliberately small: senior-level expertise and direct access, without the overhead structure of a large firm.
