(First airdate: March 27, 2018) AUDITOR ROSE ANN CARROLL – A HEAD FOR NUMBERS. Our Town Host Maryanne McNellis interviews Rose Ann Carroll, Jefferson County’s Auditor. Marriage licenses, car registration and taxes on your home are all handled by the Auditor’s office. Perhaps one of her most complex responsibilities is handling all elections from small county elections to the presidential races. Rose Ann has her fingers on the pulse of Jefferson County – a county that has seen the 60+ age category increase by over 25% since 2010.
