  • Doug Mummert
    General Manager
    302-629-9144 ext 1308

    Doug Mummert first started his career with the Hertrich Family as a Sales Consultant at Hertrich Buick GMC.  After two years, he became Used Car Manager at Frederick Ford for three years, then held the same position for five years at Ford of Easton before becoming General Sales Manager.  Doug has now been in the automobile industry and with the Hertrich family for 10 years, during which time he has worked with Pontiac, Buick, GMC, Isuzu, Hyundai, Ford, and Chevrolet. His favorite part about the automotive industry is that every day is something different. He believes that what makes the Hertrich family unique is that the family ownership is involved in the day-to day workings of the business and they really do care about their people.

    Doug wants every customer to know that customer satisfaction is his biggest goal and he is available for his customers 24/7.  Every customer that walks in the dealership should expect to be treated as a top priority by the entire team, every single time.  He wants to tell his team that "the future is up to us." 

    When Doug is not at work you can find him at the gym, watching the Eagles, or spending time with his wife, 8-year-old daughter and 7-year-old son.
