A doctor from north central Wisconsin is helping to restore the public health infrastructure in Iraq.

Navy reservist John Williams of Marshfield is in charge of rebuilding the health system in the al-Anbar province. That includes the city of Fallujah which was devastated in the recent assault by U.S. Marines.

Williams says his unit has helped supply food, water and medicine for thousands of people who have evacuated the city.

His tour of duty ends Friday, and he's expected back in Marshfield soon.
