MEET THE CLINICAL TEAM
Marguerite Lumsden
DIRECTOR and SENIOR PSYCHOLOGIST
Marguerite is our boss lady, strong and grounded leader and founder of Lumsden Psychology, bringing over 25 years of experience across the mental health sector and working across the lifespan. She holds a Master’s Degree in Community & Health Psychology and is currently completing her registrar training as a Health Psychologist.
From humble beginnings in rural and regional Queensland, Marguerite’s early experiences shaped a lifelong commitment to accessibility, equity, and high-quality mental health care for all Australians. These foundations continue to inform a practice grounded in care, compassion, consideration, and collaboration, alongside a strong belief in culture and connection as central to healing and wellbeing.
Marguerite—known warmly as “Margi” to colleagues and younger clients—brings both clinical depth and genuine humanity to her work. She has a heart of compassion and full of care and love for the people she supports, while also being a strong, grounded, and deeply dedicated leader, mentor, and advocate for her staff, community, and family. She holds a strong belief that family is more than genetics, encompassing the deep bonds formed through connection, care, shared experience, and belonging. She leads with integrity, warmth, and conviction, empowering both clients and clinicians to grow, develop, and flourish.
She draws on a broad range of evidence-based and trauma-informed therapeutic approaches including Cognitive Behaviour Therapy (CBT), Acceptance and Commitment Therapy (ACT), Dialectical Behaviour Therapy (DBT), Eye Movement Desensitisation and Reprocessing (EMDR), Narrative Therapy, Trauma-focused approaches, and Interpersonal Therapy. Her practice is guided by a focus on psychological flexibility, resilience, and meaningful, values-based living.
A strong advocate for rural and remote mental health, Marguerite is deeply committed to improving access to quality psychological care across Australia, particularly in regional communities where connection and continuity of care are vital. She brings creativity and warmth to her work with children and maintains a strong interest in the psychological impact of chronic disease, trauma, sleep, and pain, as well as performance and sport psychology.
Her extensive professional background includes work across child protection, foster care, disability services, police-related services, first responder support, and private practice, along with a strong and enduring connection to the veteran community—reflecting her commitment to trauma-informed, respectful, and recovery-focused care for those who serve.
Proudly connected to Country as a descendant of the Gamilaraay people, Marguerite’s work is grounded in respect for culture, land, and story, and a deep appreciation of belonging, identity, and connection in healing. Outside of work, she is often found photographing nature, sharing yarns around a campfire, or tending to her much-loved Therapy Herd—comprising British White cattle, a few goats, Dorper sheep, chickens, and her loyal elderly Border Collie. She believes you can never have enough plants or animals, and this love of living things reflects her deeply grounded and nurturing approach to life and wellbeing.
Marguerite consults from the East Toowoomba rooms and continues to provide outreach services to rural and western communities, supporting accessible, compassionate, and connected care.
