– Dr. Angel Munoz honored by Memorial Hermann, Northeast Hospital Authority – By Tom Broad Tribune Correspondent Neonatologist Angel Munoz knew little Nathan Reynolds was going to be a challenge. Little Nathan was a newborn and he kept dying. That’s why, back in 1996, Nathan was in Memorial Hermann Northeast Hospital’s new Neonatal Intensive Care Unit (NICU). “He kept dying on us,” recalls Margaret Miller, a NICU nurse trained by Dr. Munoz, who spent many days caring for little Nathan.
