NFP Teachers
Billings Ovulation Method
The Billings Method is an "ovulation method" of NFP which means that the bio-marker that is tracked while using this method is cervical mucus.
To learn the Billings Method: Contact Maria Ansett BSN RN IBCLC - Hillsdale area
Creighton Model FertilityCare System
The Creighton Model is an "ovulation method" of NFP which means that the bio-marker that is tracked while using this method is cervical mucus.

In Memoriam
On August 4, 2025, Dr. Peter Luea was killed in a tragic accident while jogging. He was a devout Catholic, a dedicated husband and father, and was instrumental in helping establish our current diocesan Natural Family Planning requirements and in casting the vision for NFP teachers throughout the diocese. Please pray for the repose of the soul of Peter Luea.
