A tragic loss. That’s how Dodge County Patrol Captain Molly Soblewski described the death of Benjamin Schmidt, a doctor in the Waterloo-area for more than 20-years. Schmidt was killed Monday night after a tractor he was riding tipped over. Soblewski says after going away for medical school the 48-year-old Schmidt came back to Waterloo and ran his family practice out of UW Health Partners in Waterloo. Schmidt also served as the city’s EMS director.
