Tammy Hatherill
Founder, Principal Psychologist and PhD Candidate
Tammy is a registered psychologist and Principal Practitioner at Tribal Psychology. Proud of her Melukerdee First Nations heritage, Tammy honours her Palawa/Pakana ancestry (Lutruwita, Tasmania) and Anindilyakwa connections (Northern Territory), where she was raised.
Alongside her First Nations heritage, Tammy's family ancestry also reflects a rich tapestry of Celtic and Gaelic heritage, with connections to Ireland, Scotland and England. Her family history carries further threads of Northern European ancestry, including Norse and Viking influences that have shaped parts of her ancestral regions. These intersecting histories contribute to Tammy's appreciation of identity, belonging, culture, connection and the stories carried through generations.
Tammy provides evidence-based therapies including Cognitive Behavioural Therapy (CBT), Clinical and Neuro-Hypnotherapy, EMDR and Brainspotting. Her practice is grounded in a Social and Emotional Wellbeing (SEWB) framework, recognising the interconnectedness of body, mind, emotions, family and kinship, community, culture, Country, land and spirituality.
Drawing on her diverse professional experience across Corrections and Immigration, employment services, counselling and psychology, Tammy brings a thoughtful, culturally informed and holistic approach to her work. She holds formal qualifications in the therapeutic modalities she offers and is passionate about creating meaningful connections between practitioners and the people they support.
At Tribal Psychology, Tammy has created a welcoming space for everyone, recognising that every person carries their own story, history, identity and lived experience. Her philosophy is simple: understanding people begins with listening, connection and respecting the whole person.
Meet Our Therapy Dogs
These two friendly faces are part of the Tribal Psychology team
🐾❤️ Meet Pebbles and Foxy – our furry friends at Tribal Psychology! ❤️🐾
We’re delighted to introduce Pebbles and Foxy, who are both coming up to 3 years old and are very much part of our Tribal Psychology family.
🐶These two little personalities absolutely love people and enjoy being around others. They’re often happiest simply being close by — whether that means curling up on your lap, quietly resting at your feet, or occasionally deciding they would rather sit with the psychologist! 😂🐾
They may even offer a little extra comfort, a friendly face or a gentle reminder that sometimes, the simple presence of a much-loved animal can bring a sense of calm and connection. There’s something special about the companionship of dogs and the comfort they can bring, particularly on days when we might need a little extra warmth.
Of course, they are still dogs, so you might hear the occasional bark when something catches their attention. We think that’s just part of their charm!
We also understand that not everyone feels comfortable around dogs, and that’s absolutely okay. We want everyone who visits Tribal Psychology to feel welcome, safe and at ease.
Pebbles and Foxy will usually be in the office with us. If you enjoy having dogs around, they may be there to offer a friendly hello or simply keep you company. If you would prefer not to have them present, whether you feel uncomfortable around dogs, have allergies, or simply prefer a dog-free space, please let us know. We will happily ensure they are elsewhere during your appointment.
Your comfort, needs and personal preferences always come first. 💚We look forward to introducing you to our little companions, should you wish to meet them!
🐾 Pebbles and Foxy — little paws, lots of love. 🐾
