Dr Tom van Hagen BSc, MBBS, FRACPMedical Oncologist
Born and raised on a little known island in England (Hayling Island), I moved to London to train in medicine at the Royal Free Hospital and after working for 3 years in London, emigrated to Perth in 1998.
I have been training in oncology since 2002 and became a consultant in 2008. In 2009 I completed a fellowship in melanoma and gynaecological cancers at The Royal Marsden Hospital, London. Since then, I have worked as a Medical Oncologist at Royal Perth Hospital until the department’s closure in February 2015 and now continue to work at St John of God Subiaco Hospital. Although I treat all cancer types, my speciality areas of interest include melanoma (Consultant for the WA Kirkbride Melanoma Advisory Service), upper gastrointestinal, colorectal (Consultant for SJOG Colorectal Multi-disciplinary Team), lung and head and neck cancers.

Away from work, my main goal in life is to spend as much time as possible with my beautiful family (my wife Naomi and daughters Ella and Abby), living (and loving) life, and travelling as much as possible to explore this huge, fascinating and exciting planet. I encourage all my patients to do the same!

KathPractice Secretary
Kath is our wonderful secretary who will welcome you to our rooms.

Kath has been with us for almost ten years, and continues to do the job of two people! She will help make all your appointments as required, including the ‘Ivy Suite’ (our day unit for treatment/chemo), radiology and other requests or information that you may need. Kath is extremely helpful and efficient, as well as being friendly and putting everyone at ease as soon as they enter the rooms.

If you’re a football fan and don’t like the Hawks, apologies in advance!

As you may have guessed, I am Tom’s lucky wife. Kath keeps the rooms alive on a daily basis and I help in the background and try to maintain Tom’s sanity!

I am also a Clinical Pharmacist, working in Clinical Trials in the Bendat Family Comprehensive Cancer Centre Pharmacy and running Hope Cancer Care Products, a website for advice and products to help manage cancer treatment related side effects.

Around work commitments, I like to keep fit and healthy, enjoying the gym and walking our gentle giant, Katniss the leonberger. I am also constantly planning our next holiday. In such a stressful industry, I think it is so important for our family to have regular breaks in order for Tom to recharge and continue to provide the best care for his patients.

I graduated from University of Western Australia in 2004 and completed my training at Sir Charles Gairdner Hospital and Royal Perth Hospital. I spent a year in Sydney working at St Vincent’s Hospital. I previously worked at St John of God Subiaco until I had my third child! Now, I mainly provide a locum service for Dr van Hagen. My interests in oncology are breast and colorectal oncology.

I have three young children and when I am not working, I spend most of my time trying to organise their busy social life! Ok, maybe I also spend some time online shopping.
