Oleksandr Volodymyrovych Hereha was born on 27 June 1967 in Horodok, Khmelnytskyi Oblast, in what was then the Ukrainian Soviet Socialist Republic.

From 1984 to 1985, he served in the Soviet Army, and he subsequently studied at the Khmelnytskyi Cooperative Technical School [uk] from 1987 to 1990 before graduating from the Lviv University of Trade and Economics with a specialisation in organisational and administrative management.

[1] In 2003, Hereha and his wife Halyna founded Epicentr K LLC, which later became Ukraine's largest chain of construction and household hypermarkets, Epicenter.

[7] The acquisition of the new assets brought the total area of land under cultivation of Epicenter Agro's agricultural enterprises to 160 thousand hectares in 5 regions (Vinnytsia, Khmelnytsky, Ternopil, Kyiv, Cherkasy, and Zhytomyr).

[12] In 2020, Epicenter K entered into an agreement with the Polish company OTCF to develop a mono-branded 4F store chain in Ukraine.

[13] In the same year, Epicenter began developing the country as a franchise of The Athlete's foot (TAF) sportswear and footwear chain.

[14] In March 2022, Multiservice dry cleaners were launched in the chain's stores, with the first outlets opening in a shopping center in Ivano-Frankivsk and on Polyarna Street in Kyiv.

[19] In the 2014 Ukrainian parliamentary election, he won re-election with 73.86% of the vote, defeating the next-closest challenger, Myroslav Musiy, from the People's Front.

In the first days after Russia's full-scale invasion of Ukraine, the co-owners of the Epicenter allocated more than 400 million UAH to help the Ukrainian military.

[31] Together with the Kyiv City State Administration, in February 2022, the Humanitarian Headquarters was organized to provide the Armed Forces, the military and the population.

[34] In July 2022, Epicenter supported the initiative of the country's First Lady Olena Zelenska and the UNITED24 fundraising platform to raise funds for ambulances.
