I would like to express my sincere appreciation and gratitude for the professional and excellent service you and your team afforded us when wiring our 7th floor and meeting our rigorous deadline. Without Delta, I fear this project would not have been completed in time. Your project lead is an asset to your organization -he knows his trade better than anyone I have seen, and his expertise and competency is most prevalent when he is managing his crew. Please allow this letter to serve as some small testament to his technical and managerial abilities.
