1907 – A Humble Beginning

William Howard Craig MD

William Howard Craig, MD originally founded San Antonio Regional Hospital at the corner of Arrow Highway and San Antonio Avenue. With only 18 beds and a staff of 5 physicians, the new hospital brought much needed medical care to the beautiful inland valley. Dr. Craig graduated with a degree in medicine from Johns Hopkins University, known as the College of Physicians and Surgeons of Baltimore, in 1886. He served the Upland community as a general practitioner and surgeon for 37 years.

1919 – Young Nurses in Training

Young Nurses in Training

Not only did San Antonio Hospital minister to the sick directly, it also conducted a training school for nurses. The San Antonio Hospital School of Nursing graduated its first nurses in 1919. The wage scale during nurses' training began at $1.50 per month for the first year and increased to $2.00 a month for the second and $3.00 for the third. The superintendent of nurses received $100.00 per month. The nurses shown here are having tea in their boarding house—quite a civilized existence!

When Dr. William Howard Craig began caring for his community over a century ago, our patients came from just a few square miles. As the population grew, our hospital expanded to meet the growing demand for healthcare services. As the decades passed, our original community hospital with basic services became a sophisticated healthcare organization with advanced technologies to serve patients from throughout the Inland Empire. We literally outgrew our name and based on input from our community, we became San Antonio Regional Hospital.
