About Us

Quality you can see since ’93

Serving the Black Hills Area

The Family Business

My name is Brian Powell (pictured, left), owner of Little Slim’s Trim Shop LLC, since 1993, located in Rapid City, South Dakota. I have over 35 years of experience in the upholstery business. I started doing upholstery work in my parents’ shop (Slims Auto Trim) that was opened in 1961.

I carry my Dad’s name (Slim) in the business name, as well as my parents’ traditions, quality, and values in every job I produce for my customers. Now a 3 generation company because our youngest son, Aaron has been working with me for many years now.
