Olga Malkina was born in Russia. She graduated as a performing musician, majoring in both piano and organ at Kurmangazy Conservatory in Almaty (Kazakhstan) and followed international master classes with organists, including Arturo Sacchetti (Vatican City) and Christoph Krummacher (Germany). In the Netherlands, she was regularly coached by pianists Elly Salomé and Viviana Sofronitsky. At the Royal Conservatoire The Hague, her coaches are organist Jos van der Kooy, and fortepianists Bart van Oort and Petra Somlai.

She makes her own arrangements for piano and organ, or for combinations of piano/organ and other instruments. Over the years, she has released several CDs, both as a soloist and with various colleagues, covering a varying repertoire, which are regularly played on Dutch classical radio stations.

Her extensive repertoire comprises orchestral, chamber and piano music from the baroque and romantic periods, and works by contemporary composers.
