Our Team

Sustainable Development is also about People

This image of sustainability is not just in our services and what we build, but in our people, too. It’s in how they develop and grow with us while becoming trusted members of our community.

Sustainable communities are developed by service to others. It begins with our management team setting the example. By serving on boards and donating their time and resources, leaders not only help develop sustainable organizations, they model a culture of success to our entire team.

Success for us is not marked by how much we receive, but in how much we give. And giving for us, to achieve a meaningful level of sustainable development, is nothing less than a total team effort.

In addition to the staff shown below, but not shown, are our office support staff and site superintendent personnel.
