On the weekend of Hurricane Sandy we couldn’t find anyone to help us. Our client in Lower Manhattan desperately needed 10 tractor trailers of pre-bagged sand to prepare for the storm. Within 3 hours Celtic had scrambled a team in place and the trucks were on their way.Celtic really saved the day for us and our client.
