Warren Brussee began writing after retiring from GE, where he managed an engineering team and was trained in Six Sigma. Frustrated by overly complex resources, he authored Statistics for Six Sigma Made Easy, followed by two more books with McGraw-Hill. His interest in economic trends led to The Second Great Depression, later updated by Wiley as The Great Depression of Debt. He also published a children’s book, Laoch the Guide Dog Puppy, and a mystery novel, The Child Remover, showcasing his diverse writing interests across nonfiction, economics, and fiction.
