Tami Howard has witnessed a lot and experienced even more during the past 41 years she has worked at Marshall Medical South. She started when the hospital had only two floors and no computers. She helped convert the hospital from paper to electronic medical records in the 1990s and more recently helped steer it through a complicated conversion that replaced the aging system. That task, which took a year of preparation and training, turned out to be her final accomplishment. She is hanging up her scrubs and going home for good.
