About Us

John’s Service and Sales was started in 1962 by John E. Senica with nothing more than hard work and a passion for serving others. John started the company in his garage where he used a donated pick-up truck from his best friend to get his first job. The company quickly grew with his father-in-law joining the team as well as several other local friends.

As John’s continued to grow the business moved from the garage to a local store front. In the 1970’s his two sons joined the team as well. In 1980, John’s built its current location in the heart of downtown Oglesby. It is conveniently located in North central Illinois and is capable of performing work throughout the state of Illinois and surrounding states.

Today, John’s is a third generation family owned business with over 40 dedicated full time employees. Although John E. Senica has passed, his legacy remains in the hearts of his family members who currently own the business. His son, Randy, and grandsons John V., Nathan, Luke, and Sam Senica all work hard to continue the example of hard work and dedication to clients that John taught them.

Our mission is to provide customers with superior workmanship and outstanding customer service through honesty and integrity.
