About Us
Serving Commercial Fleets Since 1991
Columbia Fleet Service has been committed to keeping commercial vehicles on the road since 1991. What began with a single road service truck and a pickup has grown into one of Central Maryland’s leading commercial fleet service providers.
In the early days, Pat’s father handled roadside service calls for customers he’d built relationships with over the years while performing repairs and yard work wherever help was needed. As demand grew, so did the business. One shop became a larger facility, new equipment was added, and the company continued expanding to better serve commercial fleets throughout the region.
Today, we’ve proudly operated from our Jessup headquarters for more than 16 years, serving customers throughout Central Maryland and the Baltimore-Washington metro area.




Built Around Fleet Customers
From the beginning, our focus has been on supporting commercial vehicles and the businesses that rely on them every day. We understand that every hour of downtime affects schedules, customers, and profitability, so our goal is always to get trucks, trailers, and equipment back in service as quickly and safely as possible.
Whether you operate a single work truck or manage a large commercial fleet, we tailor our services to your operation. Columbia Fleet Service provides complete fleet support, including heavy-duty truck and trailer repair, mobile fleet maintenance, roadside service, heavy-duty towing and recovery, construction equipment transport, crane and rigging services, collision repair, DOT inspections, and preventive maintenance.
Experienced People. Greater Capability.
As our company has grown, we’ve continued investing in the people and equipment that allow us to handle jobs of every size. Our ASE-certified technicians bring years of experience to every repair, and every employee is drug-screened before hire to help maintain a safe and professional work environment.
Our fleet includes 15 fully equipped mobile service trucks, multiple heavy-duty wreckers, a 40-ton rotator, Landoll trailers, tractors, flatbeds, and other specialized equipment. Combined with GPS-equipped vehicles and experienced operators, we’re prepared to support everything from roadside repairs to complex recoveries, equipment transport, and fleet maintenance throughout the Mid-Atlantic.




Trusted Throughout Central Maryland
Columbia Fleet Service has earned the trust of commercial fleets, municipalities, contractors, and government agencies by delivering dependable service and honest recommendations. We’re proud to support organizations including the Howard County Police Department, the Washington Suburban Sanitary Commission, and the Maryland State Highway Administration.
We’re also active members of the Maryland Motor Truck Association, are an AMBest Service Center, and we’re a Cottrell Warranty Dealer. These partnerships reflect our ongoing commitment to maintaining high standards throughout every aspect of our business.
Family Values Still Guide Us
Although we’ve grown considerably since 1991, we’re still a family business built on the same values that helped us get started. We believe in treating customers fairly, providing honest diagnostics, remaining flexible when unexpected problems arise, and working to minimize downtime for every customer we serve.
Giving back to the community is important to us as well. We’re proud to support Casey Cares, helping provide memorable experiences for terminally ill children and their families.
More than three decades after opening our doors, Columbia Fleet Service continues to help commercial fleets throughout Central Maryland stay productive with dependable repairs, responsive roadside service, and the equipment needed to handle jobs of every size.
