Gregory was born in Gainesville, Florida, moved to Dubuque, Iowa before the fifth grade, graduated from Iowa State University and earned a Masters at Auburn University studying fish. After marrying a blue-eyed tall blond by the name of Karen Joan Schimek, from Milwaukee, they resided for a short time in Ankeny, Iowa, and discovered he couldn’t make any money growing fish in the arctic. He landed a job as a farm manager on Alabama’s largest catfish farm. He made his first attempt at floating a pickup truck there. He then was hired by Auburn University as an extension specialist where he could tell all the other farmers about the floating characteristics of pickup trucks. He then met his writing mentor, Aileen K. Henderson of Brookwood, Alabama, and she suggested that perhaps he should write a novel about sinking trucks. In the meantime, at the age of forty-four, he suffered a major midlife crisis and then proudly graduated fourth in his class at the Tuscaloosa Police Academy. He served ten years as a deputy sheriff for Hale County and spent twenty years writing his debut novel, Blue Green. Karen and Greg reside in Greensboro, Alabama, and have two grown sons, Andrew and Jason. He has run eleven half-marathons and his doctor still says he’s too fat. Most of his writing epiphanies sprout between the bouts of boredom while running.
