Meet Dr JOHN Donnellan

Specialising in Skin Cancer Diagnosis and Treatment, Dr John M Donnellan is one of the longest serving and most experienced Primary Care Skin Cancer Doctors in Australia.

His practice has been heavily focused on prevention, early diagnosis and early intervention for skin cancer patients in Sydney since 1998.

After 80,000 Patients

Dr Donnellan has consulted over 80,000 times, treated more than 15,000 skin cancers, and in excess of 250,000 pre-cancerous skin lesions. His focus is solely on preventing and treating skin cancer.

Our Motivation

Dr Donnellan studied Medicine in order to save lives.

He cared for a 43 year old State Bank executive who walked in after a game of squash wearing a singlet carrying a sports bag. The patient was asking for pain relief.

The patient had Melanoma, and from the moment he certified this man's death 6 weeks later,  Dr Donnellan resolved that he never wanted this to happened anyone else.

He will never forget the faces of his patient's wife and young children as they asked 'When is daddy coming home?'

It was that day he resolved to start the Clinic and make a difference.

Dr Donnellan has exclusively practised in the area of early diagnosis and treatment for skin cancer ever since.


Dr John M Donnellan is a fully qualified and Registered Medical Practitioner and is a full time Primary Care Skin Cancer Doctor.
