Calvin Calvin Smith has worked at PathAdvantage almost since it began. He is truly one of PA’s most valued, devoted and long-standing team members. Originally a courier, Calvin now works in the laboratory, in specimen accessioning and processing. Calvin is a man of few words, and lists “Life, the country and PathAdvantage” as his passions. He is much more than this, however; Calvin is a devoted father and husband, is a strong participant in his church and related charities, and also loves the Cowboys and playing basketball.
