Meet our Team
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.
JOSH MERCER
Service Team
Josh has been at Duncan’s since 2008. He is a sixth generation auto worker, descendant of Samuel Bailey of the Bailey Company out of Amesbury, MA, who, in collaboration with Thomas Edison, developed one of the first electric cars, the Bailey Electric. He spent more than 12 years performing diagnosis and repair before he becoming a Service Advisor early in 2020. Josh lives with his wife, Melissa, and daughter, Ruby in Nashua NH.
Olivia Patsfield
Service Team
Olivia is one of our Service Advisors (miracle workers) here at Duncan’s. In 2004 Olivia acquired a degree in Automotive Technology and become an automotive technician for 6 years, 2 of which she spent fine-tuning her proficiency in Mercedes-Benz diagnosis and repair. She has been with us for 3 years and is fluent with translation of “vehicle-ese”, helping to create a foundation of trust transparency with our clients.
CELESTE DUNCAN
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.
Craig Duncan
Old Man Duncan
Craig Duncan is the founder of DEA and former owner. He is also Ben’s father. Craig opened the shop in 2004 after spending many years as a Saab tech. Affectionately known as “OMD” or Old Man Duncan around the shop, Craig will still come in regularly to say hello or share a joke.
