The earliest mention of Stom is in Rome in 1630 but acording to some sources he came from Amersfoort and may have trained with Honthorst in Utrecht. He later worked in Naples and Palermo as well as Rome. It is not known when or where he died. He painted for various churches in Italy, including an 'Adoration of the Shepherds' for the high altar of the Capuchin Church in Monreale. The great collector Antonio Ruffio bought three of Stom's paintings when the artist was living in Palermo.
