 Scheller LLC - Fertility Awareness
Imagine a world informed by the female cycle as a vital sign . . .

. . . for better outcomes in women’s lives.

What We Do

At Vital Sign FertilityCare Center (FCC), we employ the Creighton Model FertilityCare™ System to inform and teach women and couples: 

  • To appreciate the female cycle as a vital sign and fertility as a gift

  • To identify the days of fertility and infertility in the female cycle

  • To promote women’s health through the woman-specific biofeedback that the CrMS standardized notations reveal 

  • To recognize vital cycle biomarkers indicating the health of the woman’s cycle. These biomarkers can reveal imbalances & guide timely, relevant evalution of risk factors & need for medical intervention, particularly through NaProTECHNOLOGY®, for earlier diagnoses, woman-spefici treatments and better outcomes.

  • See bulleted list of advantages below

With the founding of the Creighton Model FertilityCare™ system in the mid-1970s,  it became apparent that it was the answer to the question, "Can the days of fertility and infertility be reliably determined based on a standardized system for women's observations?" The answer is yes and more!

For more background on the Creighton Model FertilityCare System (CrMS), use the web address above to reach the official site.

Please see:

for more information about NaProTechnology (NPT), the sister science of CrMS, a medical practice based on precise woman-specific biofeedback (Hilgers, 2004). Use the web address above to reach the official site. The NPT approach holds both a way to evaluate women for underlying causes of their symptoms and meaningful normal values for healthy women for comparisons.


NPT is a woman’s health science that evaluates, diagnoses, and treats health issues for each reproductive-age category of women in ways that  cooperate with the female cycle and read it as a vital sign. CrMS and NPT fill a niche for accurate data that researchers and clinicians need in order to provide better healing options amidst the biological complexities of the female patient’s life in the modern world.

The mission is to bring awareness to the benefits of the fertility appreciation approach in the context of mitochondrial and rare diseases in order to lower childbearing risks and improve outcomes for women's and family health.

Testimony#1 from a single woman in perimenopause 

“Soozi recently started teaching me the Creighton model. I’m 48 and it can be hard to learn a new habit, but Soozi’s expertise combined with her innate compassion and gentleness make everything seem simple. She has a gift for explaining sensitive topics in a loving way that is easy to receive and learn!”

Dr. Duane's testimony #2: Through her personal and professional experience, Soozi is committed to educating her peers about the important role charting the female cycle can play in monitoring and managing rare diseases related to hormonal health.

Dr. Marguerite Duane, a board certified family physician, is co-founder and Executive Director of FACTS – the Fertility Appreciation Collaborative to Teach the Science, an organization dedicated to educating healthcare professionals and students about scientifically valid natural or fertility awareness based methods (FABMs).

Testimony #3 from a single woman managing long cycles 

Her availability and flexibility allowed me to find time in my erratic schedule to prioritize my fertility health.  Even though female fertility and its issues can seem confusing or burdensome, working with Soozi has helped me to appreciate my fertility and myself as a gift!

The Practitioner’s Role

CrMS practitioners provide services to couples or single women on an individual basis because, while thepatterns of fertility can be generalized, the clients’ situations are unique, and instruction needs to be personalized.


CrMS in the Perimenopausal Years

Prior to menopause, whether they are married or single, women can have a great need for the woman-specific biofeedback the Creighton Model FertilityCare™ (CrMS) can offer them as they undergo the transition.
