Since May 2021, Cazo has been working with Russian art expert Ekaterina Nikolaeva Tendil, a member of the Syndicat Français des Experts Professionnels en objets d'art et objets de collection (SFEP).

She is an art historian and a specialist in the European art market. She has a doctorate in the history of white emigration. For several years now, she has been advising auction houses in France (Paris, Lille, Morlaix, Côte d'Azur) and Monte-Carlo on the appraisal and valuation of Russian works of art (various objects, paintings, silverware, icons, goldsmiths' and silversmiths' pieces, old letters and manuscripts, rare books).

Together we organise three major auctions a year devoted to Russian art.
