Our Practice

In all aspects of patient care, effective communication is paramount to achieving patient satisfaction. One of the core values of my practice is ensuring that every patient understands all aspects of their diagnosis and the clinical care plan that has been developed for them.  Myself and my team take pride in developing a strong rapport with not only our patients but their loved ones, who also play an important role in a patients’ journey to recovery, not just physically but emotionally.

Dr Paul Chen

I’m a specialist Breast, Endocrine and General Surgeon with extensive experience in oncoplastic breast surgery, thyroid and parathyroid surgery with the utilisation of nerve monitoring.

I completed my surgical training at St Vincent’s Hospital and Royal North Shore Hospital in Sydney after graduating from the University of Auckland. I then entered a two year post-fellowship training with BreastSurgANZ in oncoplastics breast and endocrine surgery at high volume centres in Perth and Melbourne. In pursuit of techniques in the forefront of breast surgery, I completed further training with world renowned oncoplastics breast surgeons in France and Italy.

In 2018, I attained a Masters of Surgery in Oncoplastics Breast Surgery and was awarded the John Lowenthal Medal for research from the University of Sydney. I have been widely published in surgical peer reviewed journals and have presented internationally in a wide spectrum of surgical topics. I continue to have involvement in the field of oncoplastics now teaching oncoplastic surgery to training breast surgeons.

Effective communication is critical throughout all aspects of medical care and I hold this as one of the core values of my practice. Furthermore, I am a firm believer in achieving patient satisfaction by combining excellent oncological result with maximal aesthetic outcome, delivering the best possible patient care.

With Taiwanese heritage I am multilingual and fluent in English, Taiwanese and Mandarin.

Practice Secretary - Kate

Within Dr Chen’s practice my aim is to enhance patient services by creating a positive workplace culture and developing and implementing new systems that will streamline the patients experience where possible.

I really love my job and particularly enjoy interacting with the patients and their families. I am always ready to welcome our patients with a warm smile.

Aside from being Dr Chen’s practice manager, I am also an administration officer at the Breast Clinic in Chris O’Brien Lifehouse. No two days are the same for me and I am very glad to take on both roles!

Outside of my work, I am a hobbyist photographer and I enjoy playing volleyball and badminton.
