About Peak

Our Story

Our founder’s vision for vital, thriving, and meaningful work thrives within our team today. Over a decade ago and after half a lifetime of working in public service, David Roberts left the safety of a full-time job to start an environmental consulting firm called Kulshan Services. Over the past ten years, we built a solid reputation for getting things done.

Kulshan Services rebranded in 2020 as Peak Sustainability Group and have grown from a single-shingle consultancy to a firm of twenty-plus environmental, science, and sustainability professionals. Peak’s stellar team is willing to roll up their sleeves and work on some of the stickiest, wicked problems facing our planet!

We are determined optimists and exist to help you plan and act so that you and our world can thrive.
