About Us
Directors of WOOMB International
WOOMB International – World Organisation Ovulation Method Billings – continues the work of its founders the late Drs John and Evelyn Billings who established the Billings Ovulation Method® of natural fertility regulation. The Billings Ovulation Method® is a Method which empowers women, through knowledge of their patterns of fertility and infertility and the time of ovulation, to achieve or postpone pregnancy and to monitor their reproductive health.
Our Directors are passionate about:

Training and updating teachers of excellence
As one of the first group of teachers in Melbourne when the Drs Billings decided to spread the Method by women to women, Marian very quickly learned of the importance of the competent teacher. She is passionate about ensuring that all Billings Ovulation Method® teachers have the ability to expand their knowledge and skills to ensure that the authentic Billings Ovulation Method® is offered to all. She has been involved in the development of the curricula for the WOOMB Approved Basic and Correspondence Teacher Training Courses as well as the Extension Course and Advanced Online Teacher Training Course to ensure teachers remain upskilled. She understands the importance of quality visual aids and works to ensure the availability of PowerPoint presentations suitable for teachers and medical professionals. She was the original lead person for OMR&RCA in having Billings Ovulation Method® training courses and seminars approved for quality points with the Royal Australian College of General Practitioners.
