Meet the team behind Flossbar


Eva, Founder & CEO

Eva comes from a small town in Poland and the mean streets of Brooklyn. After graduating from Harvard in 2012, Eva worked for Bridgewater Associates, the largest hedge fund in the world. Eva dreamed up Floss Bar when she noticed how complicated it was to get a basic dental care without taking 3 hours off of work or getting offered multiple extra services. Upon further research, she realized that over 80% of Americans have gingivitis, and that the rates of those with preventable dental emergencies was consistently rising. In 2018, Eva put her Wharton MBA on hold to build Floss Bar into a household name.  Eva's goal is to improve the expedience, cost, and accessibility of health and beauty services - making others both internally and externally beautiful.
