Quickly a dispute with the city over the name, the building became the Jefferson Hotel in 1908. However, Mangum’s need for a hospital, a two-story southern addition was added to the building around 1911 and another addition of a top floor and the three-story west wing in 1929. Dr. Border’s fame as a physician and goiter specialist attracted patients from a wide area. He also created teaching hospital and added the first “Air Ambulance” in OK, possibility the United States.

The next occupants of the building were young women of the National Youth Administration (NYA) project. Their sponsor and house mother was Mary McGregor, wife of Dr. Frank McGregor.

In 1948 the Baptists purchased and operated the “Southwest Baptist Hospital” for 17 years before selling it to the City of Mangum in June 1965. The city moved the hospital facilities to a new location in 1967. In 1973 the city leased the building to The Old Greer County Museum and Hall of Fame Inc.
