The Twin Cities FertilityCare Center is one of the first teaching centers established in the United States. Officially incorporated in 1975, it was then known as the Twin Cities Natural Family Planning Center. The purpose was to provide the highest quality instruction in natural family planning through education in the original Billings Ovulation Method. In 1978, the Twin Cities Center adopted the Creighton Model standardization for teacher (practitioner) training and client education. More than 30 years later, our team of practitioners continues to find joy in helping women and couples to gain a deeper understanding of and appreciation for their fertility.
