Gail Warrior has held many titles in her life: Boss. Mother. Even former body builder.But there’s one that probably suits her best: Entrepreneur. She started a construction- management business in a male-dominated industry, founding Warrior Group in 1997. She grew the Dallas-based company gradually until she landed her share of a $40 million contract in 2006 to provide modular Army barracks for Fort Bliss in El Paso.Today, Warrior Group pulls in more than $150 million in revenue every year.But it hasn’t always been simple.
