Preble Street assumes operations of two temporary shelters in Lewiston Share Preble Street last month took over operations of the 44-bed quarantine and temporary wellness shelters in Lewiston that had been run by Community Concepts Inc. since early last year. “The critically important role of emergency shelters has never been more evident than over the last year,” said Preble Street Executive Director Mark Swann. “CCI staff have done a remarkable job managing the Lewiston shelters, and we’re looking forward to working with them to continue providing this critical resource.” Many CCI shelter staff will continue their positions as Preble Street employees.
