We're sisters, best friends, and co-CEOs. Here's a day in our lives running our dental tech company.

"We first led a public pediatric dental clinic in a rural area of Switzerland together, treating children from low-income families. We realized we had to change something in dentistry because of ineffective technologies, parents' lack of awareness, and anxiety about seeing the dentist. Haley and I built the first dental support organization, or DSO, in Switzerland."

"We came up with the idea of a fear-free dental office in our 20s. We put all of our savings together, about $100,000, and got a seven-figure loan. We opened Swiss Smile in the main station in Zurich at the end of 2002. Our office was open every day from 7 a.m. to 9 p.m."

"One day, we discovered a formulation that can treat small cavities non-invasively, without a drill. We sold everything and put all our resources toward this innovation."

Dr. Haley and Dr. Goly Abivardi, co-CEOs and founders of vVardis, are sisters who studied dentistry at the University of Zurich. After working together at a pediatric dental clinic serving low-income families, they identified critical gaps in dental care: ineffective technologies, parental lack of awareness, and patient anxiety. They established Switzerland's first dental support organization (DSO) and opened Swiss Smile, a fear-free dental office concept in Zurich's main station in 2002, operating from 7 a.m. to 9 p.m. daily. The successful concept expanded internationally to India, Russia, and other countries. Their breakthrough came with discovering a non-invasive formulation to treat small cavities without drilling, leading them to redirect their resources toward vVardis.
