​Whilst having her three children, she completed her BA and MA in Art History, majoring in The Dutch Baroque Arts from the 17th century at the Courtauld Institute of Arts. She started as a College Lecturer, but soon after started her own company - Art Historical London offering art historical lectures, museum visits, courses, tours, travel and events from Amsterdam, London and New York, and since 2020 online.

A fully accredited PTLLS lecturer, she also teaches on the public program of the Dulwich Picture Gallery, for Roundtable, the Timken Museum and the New York Adventure Club in the States, for Academy Travel and the Art Academy in Sydney, and for a number of institutions in the Netherlands. Mariska can provide live, online and recorded lectures for groups or individuals.

N.B. From summer 2023 Mariska will be living between London and Amsterdam, available for jobs in both countries. Travel will only be charged within the country where the event is taking place.
