My nonprofit business, the L.A. Kitchen, was looking for the right company to help rep us as we built out a new kitchen/social enterprise in Los Angeles. This was the first kitchen I’ve built from scratch, so I needed a real pro…but more importantly, a pro who didn’t see us as just another client. I was looking for a person who shared my sense of purpose, who really cared about “why” I was building it. I found that person in Sean Leonard. He’s a pro’s pro…but more than that, he’s a great guy. He and his team are rock solid. Timely, knowledgeable, professional and great people to do business with. We can’t say enough good things about them.

I want to start by saying that I could not have handled this project without the help and guidance of Sean’s team. Their professionalism is exemplary. Each member of the team, Sean, Pia and Dennis had their own “specialty” during the course of the project and all of them had a wonderful calming demeanor that made it a pleasure to work with. They kept the project progressing by not only maintaining detailed records of the myriad issues and decisions but by communicating consistently and often with the entire team. A project like this has so many moving parts and so many players that their roll was pivotal in maintaining the project timeline. The paperwork was overwhelming yet they kept detailed records throughout and tracked the various expenditures always analyzing them to protect our interests. We found them to be exceedingly fair and diplomatic in handling any conflicts or misunderstandings. Their in-depth knowledge of both construction processes and methods was not only very educational to our team, it was reassuring to us as clients navigating new territory.
