We take pride in being a company that treats every customer with professionalism, honesty and integrity to create the highest level of trust between all parties. At National, we encourage an open exchange of ideas and stress teamwork over titles.


The nature of our business – quarrying rock from the earth – makes being a good community neighbor challenging at times. The people at National understand the need to work extra hard to meet and exceed obligations to the communities in which they work and live. From blasting to processing, from land reclamation to community involvement, National employees bring the very best they have to work each day and work hard to be the very best in the industry.

Work-Life Balance.

A company culture built on mutual respect makes it easier for us to work together and to relax together. Believe it or not, many of us bring our families back to National outside of work hours to enjoy a barbecue or a swim at Limestone Lake, an old quarry we turned into a private recreational facility exclusively for the benefit of our employees. This is just one example of the family-friendly environment that we value at National Lime and Stone. We believe that a healthy life outside of work enables us to focus when we are at work, allowing us to deliver top-quality services to our customers.

Career Advancement.

We pride ourselves in having a team of people who are dedicated to and rewarded for the success of our Company. The National Lime and Stone Company is an industry leader in the development and implementation of continuous learning practices for all of our employees. We take an interest in each person as an individual and believe in providing opportunities for our employees to learn and grow and have a strong philosophy of promoting from within our own team. The National Lime and Stone Company is proud of the professionalism and “Can Do It” focus of all of our employees. The employees’ commitment to life-long learning is the standard of excellence that separates National from the competition!
