I have total faith in Dr Koliou and his ability to provide me with the best, evidence-based advice. I trust him implicitly to ensure I receive the best treatment available to me. He’s a fantastic oncologist.
Outstanding clinical care, compassion and professionalism – an exceptional team I cannot speak highly enough of Dr Koliou and his PA, Chantelle Smith. From the outset, the care, understanding and professionalism I have experienced from them both has been truly exceptional. Dr Koliou combines outstanding clinical expertise with a genuinely compassionate, thoughtful and patient-centred approach. He listens carefully, takes concerns seriously and communicates with clarity, kindness and reassurance. At no point have I felt rushed, dismissed or that my concerns were anything other than important. His ability to combine medical knowledge with genuine empathy inspires enormous confidence and makes a tremendous difference to the patient experience. Equally deserving of recognition is his PA, Chantelle, who is quite simply wonderful. Her responsiveness, efficiency and kindness are exceptional. Nothing ever seems too much trouble, communication is consistently prompt and helpful, and she approaches every interaction with warmth, understanding and genuine care. She makes you feel that you are a person rather than simply another appointment or administrative task. Together, they provide a level of service that is increasingly rare. Their professionalism is matched by their humanity, and it is enormously reassuring to know that both the clinical and administrative aspects of my care are in such capable and considerate hands. I would recommend Dr Koliou and his team without the slightest hesitation. They set an exceptionally high standard for patient care and deserve every bit of re...

I have been very pleased with my recent visit, the care and professionalism provided by Dr Koliou.

Dr Koliou really takes the time to explain everything, and answers all your questions. He really put me at ease and made sure I understood everything.
Mr Kulio is an exceptional oncologist and a truly fantastic doctor. What I appreciate most is how deeply he listens. I was not an easy patient — in fact, I was probably one of the most challenging he could have had — but he never gave up on me. Because of his dedication and the support of his team, I was able to complete my treatment and now have another chance at life. He is also very funny, and he explains things in such an easy, down‑to‑earth way that even the heavy subjects feel lighter. He has a comforting, heartfelt manner that puts you at ease straight away, making you feel safe, understood, and genuinely supported throughout your treatment. Thanks to him, I can finally move forward with my life. Thank you from the bottom of my heart.
Dr Koliou listened about my experience and adjusted treatment accordingly. Explaining the changes and offering support.
