Big Thompson Diesel and Automotive

Loveland and Northern Colorado's Diesel and Automotive repair Specialists

About Us


Big Thompson Diesel and Automotive is a company founded on a dedication to the art of customer service. With over 30 years of experience in the automotive industry, our independent repair shop in Loveland is efficient, affordable, and honest, but most importantly, we understand cars better than the competition.  We started BTDAA to be different. As an employee Erik, the owner, had seen the dark side of the automotive repair industry.  He witnessed poor management and shop owners treating employees like pawns.  They were underpaid, under appreciated and overworked. He witnessed greedy shop owners overcharging for vehicle services and thy had many dishonest upselling practices. There were overstressed flat rate mechanics flying through repairs and not thoroughly or properly diagnosing and fixing vehicles. All of the above listed contributed to Erik's decision to change the industry. When Erik and Sarah created BTDAA in December of 2011, they swore not to treat employees and customers the way they had been treated while working for others. First of all we treat all employees and customers like family. We treat them the way we want to be treated.  With our repairs, we are highly trained. We employ 2 ASE certified master mechanics.  We have many factory scan tools that are shared within the shop so we get the same data and have the same capabilities to diagnose your vehicles as the dealerships. We also have many aftermarket tools as well as factory and aftermarket trained technicians. We specialize in diagnostics and repairs that simply stump most other technicians.  We offer almost all automotive, truck, diesel, and electric vehicle services. The list of things we do not do is body work, tires, and emissions tests. Please see our Services page for more information on the services we perform. With remarkable knowledge and skill for all types of cars, trucks, ATV’s and dirt bikes, we have what it takes to give you the results you are looking for at a price that will make you smile.

Nobody knows Colorado like us.  Having worked in Loveland for over a decade, Big Thompson Diesel and Automotive has become famous for the ability to diagnose automotive problems that have stumped other companies.  Colorado has a terrain that is so different from many others, and often that takes its toll on your car.  You can rest assured that your vehicle will be at home here.
