Our Team

The team is multidisciplinary and are all present in the same location for the weekly Breast Health Clinic. The team is made up of breast physicians, breast surgeons, plastic and reconstructive surgeons, a McGrath breast care nurse, and dedicated breast radiologists and pathologists from our allied diagnostic service providers Macquarie Medical Imaging and Douglass Hanley Moir.

Dr Katrina Tiller – Breast Physician

Dr Katrina Tiller has provided comprehensive general practice care in the North Ryde area for many years. As women’s health has always been a large part of her clinical practice, and an area of special interest, she undertook Breast Physician training at Sydney Breast Clinic from 2012. Katrina enjoys working as part of a multidisciplinary team that includes radiologists, breast surgeons, radiographers and nurses to provide specialised care for women with breast concerns. As Katrina understands first-hand the vast amount of information GPs need to assimilate, she is able to help GPs negotiate the best management plan for an individual patient.

After graduating from the University of New South Wales, Katrina completed her internship and residency at Royal Prince Alfred Hospital. She obtained her Fellowship of the Royal Australian College of General Practitioners in 1995 after completing a Diploma in Obstetrics at Blacktown Hospital and general practice terms in south-western Sydney.
