She is board-certified in obstetrics and gynaecology, a certified culinary medicine specialist, and a Menopause Society Certified Practitioner.
She worked for years in private practice and academic medicine, including at UTMB, where she is an adjunct associate professor. In 2017 she developed a nutrition programme for midlife women that became known as the Galveston Diet, first sold as an online course and later published as a book in 2023.
In 2021 she shifted her focus to menopause care and opened a menopause clinic in the Galveston area, The 'Pause Wellness (now also listed as Mary Claire Wellness). She built a large following on TikTok, Instagram and other platforms by explaining menopause symptoms and hormone therapy.
Her book The New Menopause (2024) became a number one New York Times bestseller, followed by The New Perimenopause in April 2026. She runs The 'Pause Life, a website, community and supplement line, and hosts the podcast unPAUSED. In 2025 she was named to TIME's list of 100 most influential creators.
