Kate Decker
FertilityCare Practitioner

Kate has been interested in women’s health for as long as she can remember. Though she originally considered training as a doula or midwife, she eventually realized she truly enjoyed teaching. Thus, she obtained her teaching certificate and went on to teach special education for six years.

A dedicated reader and researcher, she learned the truth about hormonal contraceptives early in her marriage and, with the support of her husband, successfully taught herself a sympto-thermal method of fertility awareness to plan their family. Following the birth of their first child, they found navigating postpartum cycles to be quite challenging and sought out professional help. Their introduction to the FertiltyCare™ System taught them even more than they already knew and Kate knew she’d found the perfect blend of her interests and talents. She felt called to become a FertilityCare™ Practitioner!

Kate has a special interest in using teaching strategies to simplify challenging charting patterns for her clients. She also has personally walked the path of quitting hormonal contraceptives and knows how overwhelming and intimidating the process can feel. She enjoys supporting women in taking charge of their healthcare and finding the freedom that comes from fertility awareness.


Sarah Rooney
Certified FertilityCare Practitioner & Holistic Fertility Coach

Sarah found FertilityCare when engaged and looking for a natural fertility awareness method to help with family planning, but also to understand what was going on with her crazy cycles and PMS!  With her engineering background, the solid science behind FertilityCare and NaProTechnology was a great fit.

As a user of the FertilityCare system for almost 10 years, she has been helped with infertility, postpartum depression/anxiety, secondary infertility, PCOS, irregular cycles, continuous mucus, hormone imbalances, and PMS.  She learned so much and received so much help through the method, that she had to share it.  She became a FertilityCare Practitioner in 2011 and has been honored to help so many women and couples with their own fertility and health journeys. All the reproductive issues she has faced have helped her become a better Practitioner as well.

Sarah’s infertility journey took her to needing to balance her hormones, as well as progesterone support throughout her pregnancies. Now she is the mom of two little ones, miracles thanks to understanding the root causes of what was going on, and finding natural solutions.  She is excited to share her passion for women's health care and she loves being able to help women and families advocate for their health.
