Oleg Trofimoff was born in 1962 in the village of Tsarevo near Moscow.

From 1979 to 1984, he studied at the Abramtsevo Art and Industrial College named after Viktor Vasnetsov. His graduation work was published in Decorative Art magazine.

From 1986 to 1992, he studied at the Moscow Stroganov Academy of Art and Industry, formerly the Moscow Higher School of Art and Industry.

He has participated in more than 20 major exhibitions in Russia and abroad.

His works are held in private collections of prominent business leaders and public figures in Russia, Ukraine, Bulgaria, Poland, Finland, Sweden, Germany, Switzerland, Italy, Cyprus, Spain, France, Canada, and the United States. A number of banks and major companies have also acquired his works for their corporate collections.

In 2008, several of his works were purchased by the Naples Museum of Fine Art in Naples, Florida, and the Dallas Arts and Crafts Museum in Dallas, Texas.

Since 1990, he has taken part in art fairs and auctions in Italy (Venice, Rome), France (Cannes), Switzerland (Geneva), Germany (Frankfurt am Main, Westerbach), the United States (California, New York), and the United Kingdom (London).

Since 2008, he has been represented in the United States and Canada by Weinstein Art Management Inc. He has also worked with Lamantia Gallery in New York.

At this stage of his career, his work is strongly influenced by Impressionism. His color palette and brushwork have formed a distinctive painterly style shaped by broad creative experience and by the traditions of the Moscow school of painting.

A light-filled atmosphere that softens the sharp contours of buildings and trees is a defining feature of his recent landscapes.

The artist created many of his recent works during research and painting trips to Italy, France, the United States, and southern resorts in the former USSR.
