Restructuring is taking place at Warren County EMS. It appears the controversy that gripped the department for more than a year is quietly coming to an end.Preston Denney has been named interim director of EMS after he was asked by County Executive Herschel Wells to take the reins of the department.“I didn’t ask for it, but Herschel discussed it with me and I volunteered to try it,” said Denney. “Of the supervisors who are there, I’ve been there longer than any of the others. I’ve volunteered to do this, until they decide what they are going to do.”Denney has been with EMS since 1999.
