Dr. Sarah Maheux-Lacroix is a gynecologist specializing in endometriosis, a chronic condition affecting many women that can cause significant pelvic pain and fertility issues. She dedicates her entire medical and surgical practice to supporting and treating patients living with this condition.

In addition to her clinical work, she plays a key role in developing medical recommendations at both national and international levels. She contributes to the drafting of clinical guidelines for recognized organizations such as the International Federation of Gynecology and Obstetrics (FIGO), the Society of Obstetricians and Gynaecologists of Canada (SOGC), and the American Association of Gynecologic Laparoscopists (AAGL). Notably, she is involved in the development of Canadian guidelines for the diagnosis and management of endometriosis.

She is also actively engaged in several initiatives aimed at better understanding and raising awareness about endometriosis. She co-leads CanWISER, a pan-Canadian network that facilitates collaborative research in gynecology, and is a member of Endo-Act, an organization advocating for policy action and public awareness related to endometriosis.

Dr. Maheux-Lacroix is deeply committed to training the next generation. Since the beginning of her career, she has supervised numerous students—from undergraduate to PhD level—as well as medical residents and fellows. Her work has led to a large number of publications and presentations, and she has received career awards such as the Excellence in Research Award (2025) from the Society of Obstetricians and Gynaecologists of Canada and the Early Achievement Award (2022) from the Canadian Society for the Advancement of Gynecologic Excellence.

For her research projects, she collaborates with a large transdisciplinary team composed of physicians, basic science researchers, biostatisticians, research professionals, specialized ultrasound technologists, and patient partners. This collective effort allows for the integration of diverse perspectives and expertise, ensuring that the research is directly aligned with the real needs of women.

Through her clinical activities, research, and involvement in national and international initiatives, Dr. Maheux-Lacroix works passionately to advance knowledge about endometriosis and to meaningfully improve the lives of those affected by it.
