The Walter Reed National Military Medical Center, located along the Rockville Pike in Bethesda, provides treatment to wounded members of the military. The center is also equipped to treat traumatic brain injury patients and amputees. Staff at the hospital provide medical treatment around the world – its hospital ship, the USNS Comfort, responded to Haiti in the aftermath of the earthquake there. On Sept. 15, 2011, the hospital transitioned from the National Naval Medical Center to the Walter Reed National Military Medical Center after recieving more than 2,500 employees from the former Walter Reed Army Medical Center in Washington, D.C., as part of the federal Base Reallignement and Closure process.
