Firm Profile

Our responsibility as lighting designers is to provide
human experiences in man-made spaces.

We believe that light shapes experience.

In your space, there is a place where beauty, function and the environment can be supported and enhanced by light. With your design vision at the forefront, we help you find this place.

Since 2001, we have been creating lighting solutions as unique as our clients’ needs — through a mixture of insight, experience, and judicious use of vetted technology. With more than 30 projects having achieved LEED, NetZero, and Living Building ratings, we are committed to outstanding results.


Our team’s diverse experience and skills infuse your team with technical expertise plus unique and creative vision. We can customize a cross-discipline team to elevate even the most complex projects.


At work, we pride ourselves in positively impacting our clients and our global environment. In our daily lives, these principles remain. We use light rail and car share systems, commute by bike, participate in eco-challenges, teach, and volunteer in our communities.
