Jess Grisham is a clinical psychologist and professor at UNSW, Sydney. She is an expert in obsessive compulsive disorder and hoarding disorder.

When we spoke with Jess, we learned a LOT about hoarding disorder. Jess dispelled the (very) unhelpful myths about ‘‘hoarders,’’ and gave some interesting insight into psychotherapy for people with hoarding disorder. We also learned about some new research that is uncovering the social and emotional origins of hoarding.
