America's favorite businesses

Launched by artist Jessica Adams more than 18 years ago, Living Design Studios creates custom metalwork for commercial and residential projects, designing things like fireplaces and staircases. Some of the company's work even adorns bus stops in the nearby city of Boulder.

"We're part of a whole ecosystem in the construction industry. We work with architects, designers and other tradespeople of all kinds," Adams said.

Biggest business challenge: "We're a small company and often have to compete with really large national companies for large commercial projects," she said.

Her best advice: "If you love it, go for it -- and know that it's going to be a roller coaster of a ride," Adams said.
