Our Family

Since the beginning, the business has been built on honest, quality, and reputable work that they always stand behind.  J & R Auto Service continue to serve their customers based on the same principles as our founder.  We pride ourselves on our quality work and the reputation we’ve built over the years.

​Our goal at J & R Auto is to build long lasting customer relationships.  We know each of our customers and the history of their vehicles!  Our best advertising is word of mouth, which starts with all of our valued customers.
