Founded in 1939, Jefferson Landmark Inc. is a member-owned local cooperative. Members/owners share in the profit of the company annually through patronage dividends. We are owned by the community and are proud to be part of the community.

With our primary focus being on agriculture and petroleum, through the years we have expanded our locations, products, and services offered. Currently, we serve the community through two retail locations, a bulk petroleum facility, and a convenience store. Our experts are available to assist in all aspects, whether it be agronomy, energy, or farm and home supplies. We value our relationship with customers and suppliers and are committed to providing a professional experience with the personal attention you deserve.

We continually strive to be a good neighbor and give back to the community. We proudly support local 4-H, school and booster programs, law enforcement, and many other non-profit organizations. Proud to be your neighbors and friends, we are working with you side-by-side to help achieve a successful result.
