Isabella Mainwaring is a globally respected voice in hormone science and women’s holistic health. She works at the intersection of hormonal physiology, subconscious reprogramming, and the mind-body connection, helping ambitious women overcome burnout, hormonal imbalances, and survival-based patterns that block their full expression.
Her signature method, ThetaSomatics™, has made her a sought-after guide for women ready to regulate their nervous systems, heal trauma, and live in alignment with their biology instead of overriding it.
Isabella is the founder of ThetaSomatics™, a unique therapeutic modality that blends somatics, brainwave science, and trauma healing to facilitate deep, cellular-level transformation. This method is available through her online programs and free practices, and it's become a cornerstone in the lives of women looking to balance their hormones and reconnect with their bodies.
Through her courses, retreats, and online content, Isabella supports women dealing with burnout, PCOS, and chronic stress-related health issues. Her approach integrates cutting-edge research with ancient wisdom, emphasizing slow, sustainable healing that honors the nervous system’s pace.
She is frequently invited to speak at global women’s wellness summits, including the WYN Women’s Congress in Paris, and continues to offer sold-out retreats that provide immersive, body-led transformation for high-achieving women.
Isabella’s debut book, Hormone Balance for Dummies, cemented her status as a trusted educator in the women’s health space. Written in her signature accessible, empowering style, the book breaks down complex hormonal science into actionable tools.
She is currently preparing for the release of her next title, The Power We Hold, which explores the deeper psycho-emotional roots of hormonal imbalance and how women can reclaim sovereignty over their health, identity, and energetic presence.
In addition to her book and clinical work, Isabella Mainwaring has become a go-to expert in holistic women’s health, regularly appearing on podcasts, wellness panels, and online summits to speak on topics like:
Her content is widely shared on Instagram, TikTok, and LinkedIn, where she shares education, practices, and perspective shifts with a rapidly growing audience of wellness professionals and seekers alike.
Born in London and raised in Australia, Isabella began her career as a high-level strategy consultant. But after her own battle with burnout and fertility struggles, she left corporate life and began retraining in integrative nutrition, trauma recovery, and functional hormone health.
That turning point sparked the creation of her entire body of work - one that now touches thousands of women around the world.
Isabella currently lives in Spain, where she writes, teaches, and builds a worldwide movement of women reclaiming their power through nervous system-led healing.
