About the shop

We're T&A Auto Service

Four bays on the south side of Minnesota Avenue, a crew that knows your name, and half a century of Sioux Falls drivers handing us their keys. That is the whole business, and it has been enough.

The owners

Mark and Deb Compson

Mark came home to Sioux Falls from the North Dakota oil fields in 2016 and went to work at T&A. He learned the shop from the inside out. In April 2021 he and Deb bought it from the owners who built it.

Deb spent her career as a nurse before she came into the business full time. If the front counter here runs a little tighter than you would expect from a repair shop, that is why. She runs it the way she ran a floor.

Since taking over they have bought the building, opened a second business inside it, and kept the same promise that came with the keys. Fifty years of goodwill is not something you inherit lightly.

Take a look

A minute inside the shop

Easier to show you than to describe it.

Fifty years later

Now we look after the
next generation's first cars

The kids who rode along in the back seat while their dad waited on an oil change are bringing in their own vehicles. Some of them bring their kids. That is the part of this job we would not trade.

What we do

Three things fill
our bays every week

01

Repair and diagnostics

Brakes, check engine lights, transmissions, suspension and steering, exhaust and catalytic converters, radiators and cooling. Factory grade scan tools and a plain answer about what they found.

See what we fix →
02

Maintenance and tires

Oil changes, batteries, alternators and starters, heating and air conditioning, tires, balancing and four wheel alignment. The routine work that keeps the big repairs away.

03

Fleet and accessories

Commercial accounts with priority scheduling, plus backup cameras, keyless entry, remote start, trailer hitches and towing wiring.

Clean bays, straight answers,
a one-year warranty, and a call
before we start

Equipment changes, vehicles get more complicated, and the shop has grown into the building next door. The way we treat the person standing at the counter has not moved an inch.

Rooted here

We live here too

Our name is on the jerseys of teams our kids play on. We run into our customers at the county fair and in the checkout line. When somebody leaves this shop happy, we usually hear about it at church on Sunday.

Mark and Deb have four kids. Keaira is in graduate school studying to become a mental health therapist, and Karsin, Elsie and Jack keep the house loud. When the shop is closed you will most likely find all of them at the campsite on the Missouri River, fishing and swimming until the light goes.

Without our customers there is no business. That is not a slogan we picked, it is the arithmetic of running a shop in a town where everybody knows everybody.
