What do you enjoy most about working on S+T projects?

“I love science buildings because no two are the same. We sit down with our clients and their researchers and inventors to learn about what they do, which is always fascinating. Then we work with them to design space that greatly enhances their science. It makes us feel like we are contributing to their research programs.”
