Tracey Feltham


Director & Principal Clinical Psychologist

BA (Psychology), MA (Psychology), MPsy (ClinPsy)

Special interest in:

  • Supervision & Mentoring
  • Accredited Supervisor with the NSW Psychologists Registration Board

I opened Core Psychology in 2007 with the vision of creating a warm, and welcoming practice where our clients can access expert help with highly qualified and trained Clinical Psychologists. With over two decades of experience working as a Clinical Psychologist within the public health system, University research settings, and in private practice I am now specialising in supervising and mentoring our highly qualified team. I am passionate about helping the next generation of Clinical Psychologists grow their expertise so that our clients can not only get well and stay well, but live a life more fulfilling than they could have imagined.

I am no longer taking on new clients as I focus on the supervision and training of our fantastic team, implementing Feedback Informed Treatment so we can track the gains our clients are making, and developing ways to improve the way we deliver treatment. I have also been engaged by the University of Technology to work as a Clinical Supervisor for its Masters of Psychology students.

This includes unhealthy relationships with food and I work with my clients to help them understand the psychological aspects and causes of their eating, hunger or body image difficulties, and look at how we can make lasting changes to interrupt these patterns.

Working in partnership with my clients we aim to build self-awareness, enhance confidence and bring back a sense of direction on the road to achieving long term fulfillment.
