Sense Of Self (SOS) emerged in response to a gap in the wellness landscape: the absence of spaces that welcomed people as they are, rather than as they think they should be. As co-founder, Mary led concept development, market positioning, and growth strategy, crafting an experience grounded in empathy, sensory richness, and body neutrality.

More than a business, SOS evolved into a platform for cultural discourse—one Mary championed through press, panels, and partnerships. From Vogue to The Guardian, she spoke on the politics of bathing, the power of communal care, and the radical potential of rest when designed with integrity. Positioned as a challenger brand, SOS became, for many, the first spa that truly saw them.
