"Very professional. Completed the job in two weeks. The deliverables were as promised. They were very independent, requiring only minimal involvement from the client. However, communication with the owner could be enhanced a bit."

"We worked with Ali (sales manager) and Tony (project manager), who took the time to design a project that made sense for our property and our budget, made a number of suggestions and recommendations and were never pushy or tried to "sell" us on something. The crew really went above and beyond to provide top quality workmanship and overall we were in very good hands. Highly recommended!"
