From Body Shop to Full-Service Auto Repair Shop

Arn's journey began in 1978 in this very same location, initially opening as Arn's Body Shop. The business grew, and soon Arn's Radiator was added to the services we offered. Then, in May of 2000, founder Steve Arn saw an opportunity and decided to expand into full-service automotive repair, officially opening Arn's Auto Service.


To bring this new vision to life, Steve partnered with Casey Kloepping, a mechanic who shared his passion and work ethic. For 25 years, Casey honed his skills and business acumen under Steve's mentorship. Today, Casey is the owner of all three businesses: Arn's Auto Service, Arn's Radiator, and Arn's Towing. He serves as our full-time service writer and shop manager. What drives the team at Arn’s? A simple passion for solving problems.


Serving Brodhead, WI

At the core of Arn's Auto Service is longevity—not just in our history, but in our people and our relationships with you. 


Our Team: We're proud to have employees who treat this place like home. Most of our staff have been with us for over 10 years. For instance, Jeff, our radiator specialist, has been with us since 1978!


Our Customers: Many of you have been trusting us with your vehicles for as long as some of our employees have been here.


We work hard to maintain a reputation built on trust, not just transactions. Our technicians handle everything (excluding transmission rebuilds), and we take the time to listen and work with you to ensure you have the best experience.


Community Outreach

Supporting and engaging with our local community is a vital part of who we are.
