Mike O’Callaghan Military Medical Center’s Multi-Service Unit (MSU) is a 30-bed medical-surgical ward that provides ready, reliable care to all ages ranging from pediatrics to geriatrics.

We serve our Active Duty service members, Retirees and other DOD beneficiaries. The MSU operates 24/7.

  • Management of exacerbations of chronic health conditions such as: diabetes, hypertension or chest pain that are directly admitted from the Outpatient Clinics, the Emergency Room, or transferred from the Intensive Care Units.

The MSU is located on the third floor, utilizing the A elevators.


Visiting hours are 24/7 and are subject to change.

Two visitors are permitted in a patient’s room at a time.

Children under the age of 12 are permitted, but must remain under parental/adult supervision at all times.


Patient rooms are designed as such that there may be two patients per room with privacy curtains. The exception is if a patient requires isolation precautions and will be placed in a room alone.

Patients under the age of 18 must have adult/parental presence at all times. One parent/guardian is expected to board with the patient overnight.
