The history of the OLOS began on 1 October 2008, in the city of Dnipro, then under the name of the Effective Systems. Tetiana Troyan, the founder of the project, at that time was an independent business consultant and decided to start building her own business from scratch in order to implement her knowledge not only in the clients’ needs, but also in those of her own. This made it possible to develop the authors’ methods, which first passed the test of time, resources, and money within our company, and only then, honed and patented, entered the market and were implemented at other enterprises.
Today, OLOS has branches at 3 cities: Kyiv, Dnipro, and Kharkiv. We conduct more than 25 educational projects per month, training about 9,706 people per year.
