Where Our Consultants Have Worked

(and what it’s taught us)

In our nearly ten years of combined experience, we have worked on projects in more than 20 states across the U.S.

We’ve learned that no two communities are the same and each project needs to be built from the ground up. We don’t do copy-and-paste planning. We approach each new project with curiosity and without preconceived notions. We pride ourselves on taking the time to learn about our partner communities and consider the qualitative and quantitative data equally.
