David Yake

We were thankful to find sustainability expertise with Peak Sustainability Group. Their team examined our carbon footprint from production output, our roastery’s footprint, and our delivery fleet’s fuel usage. By measuring what matters, we have been able to better tell our story and move boldly forward on our sustainability journey.

Arnie Klaus

Peak's facilitation was essential in our organization’s ability to address critical issues with a large stakeholder group among a diversity of topics and interests. Their ability to formulate issues and move the audience and agenda in a short time frame helped us to formulate strategies and next direction.

Mark Gardner

The people at Peak facilitated all Climate Task Force meetings to help Bellingham create a climate plan. I was impressed by their reliability, consistency, and steady commitment to excellence. I would recommend Peak without reservation for work involving high analytical and political complexity on projects of critical real-world importance.

Mark Gardner, Legislative Analyst, City of Bellingham
Lyn Wiltse

Peak's work is thorough and exacting and their integrity is beyond reproach. Their technical experience and background helps clients understand complex issues and potential unintended consequences of a range of actions. David Roberts, the founder, knows the importance of stakeholder engagement and how enduring agreements come from informed consensus.

Aspirational recycling is a big problem here in the San Juan Islands. Your videos candidly illustrated our commingled recycling challenges. Peak's community outreach, videos, and survey data provided great material for our “Talking Trash” Community Forum. Peak's outreach efforts are already improving the recycling contamination issues at our Transfer Station.

Corky Smith

Call Peak if you need environmental services. Their team has done a great job addressing the complexities of Swen Larson Quarry's planning and permit process. Peak's ability to develop strategy, patiently communicate, and advocate for us has smoothed the way with the regulatory agencies. As a result, we will have predictability for our operations for many years to come.

Steve Seymour

I have worked with a lot of consultants and David Roberts is different. Our watershed process with stakeholders was successful because he and his team know how to listen. People participated because they felt heard and it was worth their time.

Since 2012, Peak has delivered the Managing Stormwater Facilities Training to homeowners. Peak provides an excellent overview of stormwater management. Their step-by-step instructions for routine maintenance can prolong the life of stormwater facilities, improve appearance, and keep them functioning properly. Their presentations play a key role in the success of our program.
