About Marjan Mazaheri
Marjan Mazaheri is a compassionate, evidence-based psychologist at MedSurg Weight Loss, specialising in supporting individuals with psychological challenges related to weight management and achieving a healthier, more balanced lifestyle. She focuses on building motivation, fostering self-confidence, and addressing emotional and behavioural barriers to success, including emotional and disordered eating.
Marjan holds a Bachelor of Psychological Science (Honours) and a Graduate Diploma in Behaviour Analysis. She has also completed postgraduate training in Clinical Hypnosis and EMDR, broadening her therapeutic toolkit to meet the diverse needs of her clients.
Using a person-centred approach, Marjan draws on individuals’ strengths — including personal resilience and social support networks — to promote wellbeing. She adapts evidence-based therapeutic techniques, including Cognitive Behavioural Therapy (CBT) and Acceptance and Commitment Therapy (ACT), to meet each client’s unique needs and goals.
Areas of Expertise
Marjan provides tailored psychological support to medical weight loss and bariatric surgery patients, both pre- and post-procedure, helping to ensure positive, sustainable outcomes. Some of the areas she works with clients on include:
- Understanding the link between emotions and eating habits
- Developing motivation and confidence to pursue health goals
- Building a healthier relationship with food and body image
- Managing stress, low mood, anxiety or self-criticism that may be affecting progress
- Addressing patterns such as emotional eating, mindless eating, or binge eating
- Supporting preparation and adjustment before and after bariatric surgery
- Improving time management, self-care, and life balance
- Childhood obesity prevention and management
- Strengthening communication and boundaries around food, family or social situations
You do not need to be seeing one of our doctors to access psychology services — anyone is welcome to book in directly. Marjan’s approach is collaborative, compassionate, and tailored to your individual goals.
Marjan's Approach
Marjan is dedicated to providing high-quality, personalised care, creating a safe and collaborative environment where clients can work towards their goals and achieve meaningful progress. She works in close partnership with the rest of the MedSurg team — including our doctors, dietitians, and exercise physiologist — to provide fully integrated, multidisciplinary care when appropriate.
She recognises that everyone’s weight loss journey is different, and takes the time to understand each client’s background, challenges, and aspirations so that support is relevant, realistic, and sustainable.
