Knoxville Postmaster Rosetta Roose works her last day on Friday. Roose will retire after working for the post office for 27 years, including the last 21 in Knoxville. Roose says she’ll miss both the people she’s worked with and those that she’s served over the past two decades. There will be an open house for Roose at the post office on Friday from 9am-2pm. Residents are welcome to stop by to congratulate and thank her.
