Behind the Mustache


After receiving his Ph.D. from Georgia Tech, Matt witnessed the worsening of Lauren's endometriosis. As they met with more and more doctors, it became clear to them how little was known about the condition. Matt decided to take matters into his own hands.

He initially delved into researching endometriosis, and later, joined the University of Washington School of Medicine, where he focused on the biology of aging, particularly the role of food and environment in inflammation and chronic diseases. Matt began investigating how different supplements worked with Lauren and her sister Catherine to alleviate their discomfort.

Eventually, he left his faculty position to co-found Semaine and now leads the formulation team! By closely collaborating with FDA-approved manufacturers, and third-party testing facilities, we promise to deliver the highest-quality products to support your well-being.
