Dr. Mike Kimbrell is retiring after practicing internal medicine for 34 years in Lancaster and seven years in the Army. Kimbrell, 68, said he’d miss the patients and people he’s worked with over the years. “Unfortunately, there’s a time when you just have to step down,” he said. “I’ll miss coming to the office.” Kimbrell came to Lancaster in 1983, looking for a small town close to a big city.
