Getting Care

Construction

Construction is continuing at Mike O’Callaghan Military Medical Center! 

The overall objective of this project supports our facility's trauma readiness mission: increasing the number of inpatient beds, as well as reconfiguring multiple outpatient clinics with state-of-the-art features and operational efficiencies. 

Keep an eye out here and on Facebook for the latest information as construction continues.  And please “pardon our dust” while we continually improve your healthcare experience.
