Gerry Maddoux is a board certified cardiologist who practiced for many years, while contributing a large number of research articles. For years, patients asked him to write down his comments in a book. Finally, he did so. Your Heart: Treat It Like You Love It! is the world's most complete resource book for the heart patient and his or her family members. A second book, 50 to 60: Now What?, is based on the principles of heart-healthy prevention. He has also made eight health-related DVDs for SmartChannel.

Dr. Maddoux then turned to medical thrillers to carry his message regarding the realities of medicine: about both those who practice it to the best of their ability, and those who choose to profit from it unduly. The dark side of medicine is the greatest story never told. But now it is, in novels such as: Oath For Sale, Harvest Time, Geronimo's Gift and Wrinkle.
