  “Your work in ensuring that the building represented the architects’ vision of a modern, architecturally stimulating building is evident in the final product. Moreover, there were many minor construction details and specifications that had not been used in previous buildings and your creativity and experience allowed us to save time and money while also assuring that these specifications were followed properly. The City of Los Angeles is known to be very stringent in its regulations and your navigation of the different city departments was instrumental in achieving our desired results”
