About us


Professional Staff

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.

What our clients say

Had brian make us 2 seats for our prostock race sleds. Beautiful work, 3 seasons of racing on them and still look like brand new. He built them right to spec for us. Beautiful job and very light. Highly recommended

Bryan DeBaere

The craftsmanship was impeccable and one year later, zero problems. The seat looks factory new again/still and I can’t imagine you could do better going anywhere else. Thanks again Brian. You rock!
