Tom Breen grew up on the Triangle X Ranch and lived there until he graduated from Jackson Hole High School. At that time, Triangle X was primarily a dude ranch having about 150 horses and mules as well as a herd of cattle until around 1970. Tom went to work, mounted on a horse, at the age of 11, working as a camp jack on pack trips into the wilderness. He worked with several old-time packers including Bill Daniels and Jack Davis. Tom was leading pack strings and pack trips while still in high school. He broke colts and mules for the ranch as well as his own. He learned to be a horseshoer and became a fine leather worker. He has made hundreds of chaps and chinks over the years. In 1985, Tom and his wife Susie moved to the Walton Ranch just west of Jackson Hole where he still works.
