Service Director, Old Orchard Nissan

Gary has worked in automotive service for more than 30 years, fifteen of them with Nissan in Skokie. Today he runs the service department at Old Orchard Nissan, and before an article about maintenance, repairs or safe driving goes live on our blog, he reads it for technical accuracy.

About

About Gary

Gary DeWig has worked in automotive service since 1993. He started as New Car Prep Manager at Arrow Chevrolet, getting new vehicles ready for their owners, and in 1998 moved to the service drive, where he spent the next quarter-century as a service advisor.

That career ran through Rizza Chevrolet, Grossinger Autoplex and Saab Exchange in Morton Grove, and then fifteen and a half years at Martin Nissan in Skokie, from 2008 to 2023. In July 2024 he became Service Director at Old Orchard Nissan, where he leads the service drive and the technicians.

In his own words: “I’ve been involved with the automotive industry for the better part of 30 years, so I have the knowledge, experience and understanding of all facets relating to automotive servicing.”

A service advisor spends the day turning what a technician found into plain language an owner can act on. That is exactly what a good maintenance article has to do, and it is why Gary reviews ours.

Customers rate him 4.9 out of 5 across 416 reviews on DealerRater (September 2026); his reviews also appear on Cars.com.
