Sinikka Vaara originally trained and worked as a nurse before studying art therapy at IATE, London, and visual arts at the Surrey Institute of Art & Design, University College, Farnham, which laid the foundation for her ongoing interest in art, creativity, phantasy, symbolisation, dreams, and the relationship between the unconscious and mental health, and interpersonal relationships. She continued studying fine art and art therapy at the University of Art and Design Helsinki, Finland, and completed training in psychoanalytic art therapy and became a licensed psychotherapist. She has maintained a private psychotherapy practice in Helsinki since 2007. Her long-term clinical supervision with experienced Finnish psychoanalysts and group analysts led her to delve deeper into group psychoanalysis. She is currently finalising advanced studies in group analysis. She also holds a BA degree in performing arts. Her background in both visual and performing arts is driven by an interdisciplinary interest in the human mind, unconscious processes, imagination, creativity, and the role of expressions and interactions in therapeutic and artistic group contexts.
