Marion grew up in Europe and Canada. Her father worked in the airline industry, and her mother was an artist, instilling Marion's life-long interests in travel, culture, and creative expression. 
Marion studied literature at a liberal arts college in Montréal before finding her path to psychology. Upon finishing her undergraduate degree in psychology at McGill University, Marion moved to the West Coast of Canada to earn a Ph.D. in clinical psychology at Simon Fraser University. 

After a year of residency at a hospital near Toronto, Marion accepted a faculty position at the University of Victoria. For many years, she trained clinical psychologists and studied family dynamics.  Marion has published many articles and chapters about her research and clinical practice but always intended to return to her love of writing fiction. 

Marion attended an immersive writers' retreat in Paris taught by New York Times bestselling author Wendy Goldman-Rohm to pursue her creative aspirations. Under Wendy's mentorship, she drafted her debut novel, THE LANGUAGE OF DREAMS, published on August 30, 2022. THE LANGUAGE OF DREAMS has been shortlisted for the BC 2023 Ethel Wilson Book Prize for Literary Fiction and the National 2023 Whistler Independent Book Award.

Marion is pleased to be represented by John Pearce, a senior literary agent at Westwood Creative Artists in Toronto .

Marion raised her family on Vancouver Island and still practices psychology in the Victoria community. She now lives on beautiful Bear Mountain with her life
partner Michael and their two cats.
