Thank you for choosing AJ's Services!

Our Story

Thank you for considering doing business with AJ’s! We are a family-owned & operated oil field service company based in the historic town of
El Dorado. Our family legacy in the oil business is currently in its 5th consecutive generation in Butler County, Kansas. Here’s our story:

The Past

The Present

The Future

Don grew up working every summer with his dad in the oil patch. After he served our country in the Korean war, Don hired on at Cities Service in the 1950s. A few years later, Don opened an oil field chemical supply company in El Dorado and eventually purchased and operated his own oil production.
Don passed away in November of 2019. He will be dearly missed by his family.

Ray began working for Cities Service in 1927, at the age of 18. Ray spent his whole working life there and retired with honor in the 1960s for his career-long faithful service.
