Through the years, Warren Petroleum steadily grew and prospered to great heights, as did the Warrens' desire to give something back to the community. On October 1, 1960, their dream finally became a reality. After five years of planning and construction, Saint Francis opened its doors with 275 beds.
In order to meet patient care requirements as well as the demands of a rapidly growing population in southeast Tulsa, the hospital was expanded in 1969 to 735 adult and pediatric beds and bassinets. The expansion included a new "Y" section to match the original structure and a seven-story specialty wing.
Planning began almost immediately for a third phase of development at Saint Francis Hospital with expansion projects planned for completion during the 1970s.
A major milestone occurred on December 3, 1975 -- the 15th anniversary of the hospital -- when the Natalie Warren Bryant Cancer Center opened its doors. It was one of the first centers where radiation therapy, chemotherapy services, laboratory and support services were grouped in a single location for the patient's convenience.
