Dr. Mary Claire Haver

Dr. Haver, a board-certified obstetrician-gynecologist, is the author and primary narrative voice of The New Perimenopause. As a certified menopause practitioner and culinary medicine specialist, she founded The ’Pause Wellness clinic to provide specialized care for midlife women. Haver writes amid a cultural and medical reevaluation of menopause treatment, leveraging her large social-media platform and best-selling books, including The Galveston Diet and The New Menopause, to translate evidence into accessible practice. Her work reframes perimenopause as a systemic, brain-first neuroendocrine transition, advocating for earlier risk screening, symptom validation, and evidence-based use of MHT.


Haver establishes her authority by combining decades of clinical practice with a personal journey that led her to question the gaps in her own medical training. After building a menopause-focused platform in response to her own symptoms and the dismissal her patients faced, she pursued advanced credentials to address the needs of midlife women. Her credibility stems from this dual perspective as both a practitioner and a patient who felt abandoned by conventional wisdom. She writes with a sense of corrective urgency, motivated by the misinterpretations of the Women’s Health Initiative data that left a generation of women undertreated.
