Rock solid science starts with rock solid scientists who have a strong desire to seek answers, reasons and explanations not just for their subject of interest but for many things that surround them. The scientists involved in the development of the Billings Ovulation Method® were Drs John and Evelyn Billings and Professors Emeritus James Brown and Erik Odeblad. What started as a collaboration between scientists became a life-long friendship.
