About O’Brien Automotive LLC
50 Years of Keeping Marshfield Moving
FROM TECHNICIAN TO OWNER
Our Story
Owner Gary Schallock has always had a natural curiosity for understanding how things work. Fresh out of high school, that passion brought him to O’Brien Automotive, where he began building his career in automotive repair.
Over the years, Gary gained the hands-on knowledge and experience that would eventually lead him to become the owner of the shop he started at.
Today, he and the O’Brien Automotive team carry that same dedication into every vehicle they service combining decades of experience with a commitment to doing the job right.
I’d put one of the older shop/classic-car photos beside this section. It gives the page some history and makes their “since 1976” positioning feel authentic rather than just another marketing statement.
HONEST ANSWERS. INFORMED DECISIONS.
Your Vehicle. Your Decision. Our Expertise.
We believe vehicle owners should feel confident about the decisions they make for their cars and trucks. That starts with understanding what’s happening under the hood.
At O’Brien Automotive, the technician servicing your vehicle will personally explain what they find, answer your questions, and walk you through recommended repairs or preventative maintenance.
No middleman. No unnecessary confusion.
Just straightforward communication from the person working on your vehicle.
Our job is to give you the information and professional recommendations you need to make an informed decision about your vehicle and its longevity.
EXPERIENCE YOU CAN RELY ON
Quality Service Starts With the Right People
Our experienced technicians bring decades of hands-on automotive knowledge to the shop. The team is trained to service foreign and domestic vehicles and equipped to handle everything from routine maintenance to advanced diagnostics and complex repairs.

We also use quality parts from respected manufacturers and suppliers, including ACDelco, Carquest, Mobil, Bendix, and NAPA, because dependable repairs start with dependable components.

This section would be great with the current team photo outside the building. The combination of an old/classic-car photo near Gary's story and the current team/shop photo here visually tells the “then → now” story really well.
