Randy and Jo Dee started JNR in 2005. They wanted to raise well-bred Quarter Horses that could go into several different directions and could be used by the whole family. 

​

In 2019, their son became interested in horses and wanted to carry on with the JNR brand if anything should happen to his parents. Randy, Jo Dee's husband and Robert's father, passed in March of 2021. JNR originally stood for Jo Dee and Randy and now stands for Jo Dee and Robert.

​

JNR Quarter Horse bloodlines include Blue Valentine, Playgun, Peptoboonsmal, Leo Hancock Hays, Doc Bar, Genuine Doc, Peppy San Badger, and High Brow Hickory.
