Founder & Faculty


Geraldine Matus, B.Sc/, Lay Midwife, HRHPE, PhD is the founder of the Justisse Method (1987), a fertility awareness-based method (FABM). In 2003 she founded the Canadian not for profit corporation Justisse College International, and served as Academic Director and Dean up until her resignation in November 2020. She designed and wrote the initial Justisse College curriculum ((C) 1987 / 2003 and the Justisse Method User Guide (1987/2009). 

Geraldine has worked as a fertility awareness-based methods educator and holistic reproductive health practitioner since 1977, and has been active in the reproductive health freedoms movement since then. She qualified as a lay homebirth midwife in 1985 (before midwifery was legal and midwives were licensed in Canada). She completed natural family planning educator training in the Billings Method, SERENA Canada, Couple-to-Couple League, and Creighton training between 1977 and 1986. Since 1980 she had the privilege of working with and to learn from North America's best complementary and alternative medicine physicians. Dr. Matus believes that a woman’s reproductive cycle (menstrual cycle) is the 5th vital sign of her health, and which depends on healthy and regular ovulatory and menstrual patterns from menarche to menopause.

She is past chair for the Core Competencies Committee for the Association for Fertility Awareness Professionals (AFAP) which oversees the development of standards and demonstration of competency for certification of Fertility Awareness Educators (FAE).

She completed her doctorate in Depth Psychology in 2014 at Pacifica Graduate Institute. Her doctoral work focuses on a psycho-physiological view of women's beauty and blood mysteries, and how they are connected to love as the glutinum mundi (glue of the world). Dr. Matus's work integrates her experience in sexual and reproductive health with a depth psychological view of healing. She believes a woman's conscious engagement with her beauty and blood mysteries is a valuable means for her to develop a profound honoring of her body as the vessel of her being, and in that way become wholly empowered in body, mind, and spirit.

Carolina Fischmann, BA

HRHP, Junior Faculty

Carolina is passionate about educating people on how to understand their bodies and live in sync with their cycles. After years of using birth control and living with undiagnosed deep infiltrative endometriosis, learning the Justisse Method was a life-changing experience.
Carolina became an HRHP in 2018 and opened her private practice, Fluência Corporal. She is the first secular fertility awareness educator in Brazil and has taught hundreds of people about the importance of the menstrual cycle as a sign of health, the use of fertility awareness for both contraception and conception, and historical, social and cultural aspects of being a woman and/or menstruator. In 2021, Carolina joined Justisse College as a junior faculty member and is extremely happy with the opportunity of teaching other passionate instructors from all over the world.
She has previous background in Anthropology and is currently pursuing a Dietitian degree. Besides her private practice teaching the Justisse Method, Carolina also advocates for reproductive justice and provides workshops in schools, universities and other educational settings.

Geneviéve Rajoy

HRHP, Junior Faculty

Geneviève Rajoy has been involved with menstrual cycles and fertility since 2009 when she began selling menstrual cloth pads as an entrepreneur with two beloved friends. Participating in fairs and workshops to explain how to use ecological pads led her to discover that most people were not aware of ALL that the menstrual cycle means. This is where her journey began.

A few years later, looking at the references in a Fertility Awareness book, she found out about Justisse College, met Geraldine Matus, and felt right away that it was what she had been looking for, which was a college that could teach her how to support people with holistic and science-based information regarding their bodies and cycles. Geneviève became an HRHP in 2018, and is probably the first secular certificated fertility awareness educator in Ecuador.

In 2021, Geneviève joined Justisse College as a Junior Faculty Collaborator. Her purpose is to continue to bring this essential information to Spanish-speaking countries, and help to train more HRHPs in South America. She lives in Quito, Ecuador, is 41 years old, has a 2 year old baby girl, enjoys her day to day, balancing family life and work. She says, “I love our profession. For me, accompanying people to discover the wisdom of our bodies and being able to make informed decisions inspires me to continue my own personal journey, looking for my own physical and spiritual balance.”


Amy Sedgwick, BSc (O.T.)

HRHP, Senior Faculty

Amy’s Justisse journey began after side effects from hormonal birth control nearly destroyed her breastfeeding relationship with her newborn daughter in 2005. Seeking a natural yet effective contraceptive alternative, she turned to the Justisse Method of Fertility Management. Through learning to chart her cycles and working with an HRHP, Amy uncovered answers to longstanding health problems and was able to reverse debilitating menstrual symptoms and achieve energy and vitality she hadn’t experienced since childhood. Since then Amy has committed herself to helping others achieve optimal health through menstrual cycle charting and body literacy. 

Born and raised in Toronto, Amy has a Bachelor of Science in Occupational Therapy from the University of Toronto and earned her certification as a Holistic Reproductive Health Practitioner in 2010.  She has been engaged in work for the Justisse College since 2014. Amy completed her HRHPE training in March, 2020. 

Through Red Tent Sisters, a business Amy started in 2007 with her sister Kim, Amy has supported individuals of all genders and sexual orientations to use fertility awareness to achieve or avoid pregnancy, and to maximize their reproductive health. In 2019, after living in Antigonish, NS for three years, Amy opened a private practice where she combines her work as an Occupational Therapist, HRHP, Arvigo Practitioner and Harner Shamanic Counsellor. Amy currently divides her time between faculty and executive work for Justisse, her private clinical practice, and doing contract Occupational Therapy work for Veterans Affairs Canada. Amy is currently studying Dynamic Emotional Integration, a unique approach to counselling and working with emotions.
