I’d like to say that it was a pleasure working with GSI. I would like to personally commend the efforts of Josh Kelly and his crew; Steven, Lee, Austin, and Trent. They went above and beyond to meet our schedule by working long hours, more importantly long “hard” hours. They are an extremely hard-working bunch who never complained and did whatever it took to get the job done, they are a crew that I would recommend to anyone. This speaks more importantly than anything else to the caliber of work that GSI performs. I believe that the relationship formed between [our company] and GSI on this project will lead to future partnerships on projects down the road and I hope that the mutual respect we’ve developed on this project will continue for years to come. Thanks again and please let Josh and his crew know that their hard work was greatly appreciated.
