The History of Shannon
In the 1930s, two pioneers changed the face of health care for the people of the Concho Valley. J.M. and Margaret Shannon brought tough work ethics, a keen business sense and frugal natures to West Texas.
Their dedication to their land, their neighbors and to each other laid the foundation for the establishment of Shannon West Texas Memorial Hospital, which grew to Shannon Medical Center and has now matured to Shannon Health System.
A pioneer by nature, J.M. Shannon brought an interest in sheep ranching, developed in Australia and New Zealand, to this area. Frugal to the point of wearing "breeches pinned together with safety pins or mesquite thorns," Shannon acquired land, insurance and banking interests, attributing his success to "always staying with the herd." A native of Scotland, Margaret Campbell, while traveling the world as a complement to her formal education, met Shannon on a ship in an Australian port. By the time the ship docked in San Francisco, the two were engaged. Two years later, they were married. Some years later, Shannon received a contract for fencing the vast XIT Ranch in the Texas Panhandle.
