Eva, Founder & CEO

Eva comes from a small town in Poland and the mean streets of Brooklyn. She graduated from Harvard in 2012, and work for Bridgewater Associates, the largest hedge fund in the world. She has been a product designer, an operations manager, and an investment researcher. She came up with Floss Bar as a customer, seeing how logistically complicated it was to get a basic teeth cleaning without taking 3 hours off of work or getting offered multiple extra services. She also has an amazing sense of smell, so at times, she cares a bit too much about the dental care of those around her (if you know what I mean). So she researched and realized that over 80% of Americans have gingivitis, and that the rates of those with preventable dental emergencies is consistently rising. She sees improving the expedience, cost, and accessibility of health and beauty services as a step in the direction making others internally and externally beautiful.
