About ESD

Designing Safer, Healthier, Sustainable Spaces for Today
 With an Eye Toward Tomorrow

Designing Infrastructure To Improve the Lives of People

We believe buildings should be designed with people in mind. When projects are created with the environment in mind, all lives are better. When plans become future-proof, tomorrow is a better place. At ESD, we believe that expertise and empathy can improve the built environment, and we work to do so for our clients. This is built on three pillars:


Recognize your goals. Understand your budget. Figure out the best path forward that redefines what is real.


We have a plan. We have a goal. What’s the smartest and most efficient way to get there? We’ll design it.

Our team of engineers and experts works with you to realize the dreams we’ve defined together

We Improve Society Through the Built Environment

We create design solutions that not only meet our client/partner’s needs and expectations but provide a safe environment to communicate, inspire, create, innovate, and evolve. To do this we champion inclusion and collaboration both in-house and with our clients.

We are committed to the environment and approach all of our work with sustainability as a fundamental construct. We strive to develop fit-for-purpose approaches that responsibly consume the earth’s resources both initially and over time.

Above all, the value we place on the health and safety of our employees and our clients through our design is paramount in our philosophic approach.

See Around the Corner

Buildings are complex. Changes in technology, regulations, and the social and literal environment mean that today’s genius is outdated tomorrow. That’s why our culture doesn’t look to only solve today’s problems…it looks to prevent tomorrow’s.

How do we do this? By combining experience with vision.

  • Ask the thousand little questions that generate the big answers
  • Employ experience-grounded innovations to find evidence-based solutions
  • Know that what we’ve done before isn’t always the answer
  • Don’t just rely on subject-matter expertise. Build empathy into every part of the project
  • Adapt. Imagine. Change.

Seeing what’s around the corner requires the confidence to be curious. We can’t wait to discover how to solve your problems.
