Dorota cleans US Cellular Plaza in Chicago. She is a resolute, diligent worker and is passionate about sustainability. She maintains her building using cleaning solutions and chemicals that are made from just three ingredients: water, salt and electricity. The solutions are created on-site, so they further help reduce the building's environmental footprint and the containers are all reusable. Dorota has had an extraordinary life – she grew up in Poland and was a professor there prior to coming to the United States roughly 30 years ago.
