Gene’s strength is to work collaboratively with his client to ensure the project meets the customer’s expectation. This project changed a couple of times based on what we found during demolition. Gene provided options and was always upfront about the cost of each option. We set out a schedule and the crew showed up on time for the day and on schedule for the week. I am very happy with the work."
