Nurses Jan Berry, left, and Cathy Butler, center, join Sally McGann, director of women’s services, in smashing a wall with a sledgehammer inside Henry Mayo Newhall Memorial Hospital’s old intensive care unit on Tuesday. At far right is pediatrician Krishan Vashistha, also participating in starting the demolition of the building. A wall-busting celebration was held in preparation of the hospital’s new 11-bed neonatal intensive care unit, which is set to open in 2011.
