HOUSTON – The Houston Christian high school senior class is stepping up to take care of healthcare workers at Memorial Hermann’s Memorial City Hospital. The seniors donated about $3,000 of their graduation funds to help provide 150 free lunches. Allen Tseng, chief operating officer for Memorial Hermann’s Memorial City Hospital, said the gesture goes a long way. The Houston Christian high school senior class isn’t just stepping up to help healthcare workers though. They plan to donate $10,000 to the Houston Food Bank on Friday to help families in need.
