Ben Duncan

Owner & Technician

Ben Duncan is a master certified Mercedes-Benz technician and the owner of Duncan’s European Automotive (DEA). His hobbies have included converting two Diesel engines plus his former home heating system to run on used vegetable oil without any kits. He is a very involved Daddy with his two young ladies, Drew and Zoë, and is referred to as “Saint Benjamin” by his wife Celeste, for his patience, kindness, and honesty.


Da Boss

Celeste is our bubbly Customer Service Representative and Ben’s lovely wife. Referred to as the “shop mom”, Celeste will make sure you are comfortable and your requests are brought to the correct set of ears. If you stay and wait for your car, she will likely woo you into having a cup of coffee while flashing her seemingly ever-present smile.
