Limestone Counselling, Coaching & Consulting is the private practice of Leanna Callum, psychotherapist, individual, couple and family therapist, social worker and art therapist.

Leanna’s work can be described as eclectic because she draws from various theories and approaches, including but not limited to attachment theory, somatic and polyvagal theory, systems theory, cognitive behavioural therapy, emotion focused therapy, family systems therapy, narrative therapy, solution focused therapy, and psychodynamic therapy.

Leanna believes in the mind’s and body’s natural ability to heal and change, and the need for trust in this process. She approaches her work with curiosity, acceptance, and compassion. She values self-determination and authenticity as key components to growth and healthy change. Her work focuses on building strengths, positive approaches to change, creating purpose and personal and relational meaning.
