It provides a broad range of medical services to active-duty U.S. military personnel under Joint Region Marianas.

Local CHamoru staff continued to offer medical care during the Japanese occupation until the hospital was destroyed in the U.S. liberation.

The hospital was re-established in its current location in Agana Heights in 1954 and treated many casualties from the Vietnam War.

In August 1899, the USS Yosemite arrived and Surgeon Philip Leach set about siting and establishing a "Naval Hospital and Dispensary at Agana [now Hagåtña]."

The sole medical providers on the island at this time were suruhånus and suruhånas, traditional CHamoru healers.

Recognizing the need for more medical personnel, the Navy began training local people, graduating the first Western-trained midwives in 1901.

For the remainder of the Japanese occupation of Guam, Sablan and the 14 CHamoru nurses were almost the only providers of medical care to the local populace.

The village of Hagåtña, including the hospital, was demolished by American naval bombardment during the liberation of Guam in August 1944.
