Who We Are

Stephanie Schull, PhD, Inventor and Founder

Prior to inventing Kegelbell, Dr. Schull was an academic who taught philosophy at university, wrote extensively and presented around the world her work in philosophy, translated a book on psychoanalysis from French to English, was Director of a School of Architecture, and served in the Executive Office of universities. 

She wanted to move from "armchair" feminism to tangibly improving the lives of women by reimagining products that are simple, safe and radically effective for millions of women everywhere.

Stephanie believes very strongly in the need for not only Kegelbell, but a company, like Matter|Mission, to destigmatize the space of women's health and give women permission to seek out remedies to the issues that have interrupted their happiness for years.
