Dr.Koliou as always very nuce and helpful. Explain the situation and answer all the wuestions
Dr Koliou always greets me with a reassuring smile. His compassion, kindness and professionalism appear effortless. I experience anxiety before appointments, but as always, Dr Koliou thoroughly explained all details of my current treatment and ensured all my questions were clearly answered.
Dr Koliou was fully invested in my journey. His care was both deeply personal and highly professional. His compassion, dedication and expertise gave me confidence when I needed it most. Every question I had through the journey was answered (and believe me I had a lot).
Panos is always there for me and I trust him the most on the management of my care. I feel blessed that he is treating oncologist and I recommend him without reservations! I feel secure, safe and happy with him.
I was so worried when I got the told the news I had breast cancer. Having Dr Koliou as my Doctor was a great help. He put my mind at ease and helped me through every stage of my diagnosis and treatment. I could not have asked for a better doctor.
I’ve been a patient of Dr Koliou for over 2 years and my experience has always been great. Dr Koliou is extremely kind, compassionate, and attentive. He is very easy to communicate and he answers my question in a clear and simple way. He, always, made sure I knew the pros and cons of my treatment and what I needed to do and when.
I have been under the care of Dr Koliou for the last 4 years and I am pleased to say that I have been treated in such an exceptional way for all this time. He is always there for me when I need him and is very supportive and compassionate. He knows what exactly to do and always has an answer or a solution to any query or problem. I highly recommend him.
Panos treats the person not just the diagnosis! Having Panos as my oncologist was a massive reason for my overall positive mental state and wellbeing during treatment. No only is he medically “all over it” but the genuine care and passion he shows truly allowed me not to worry because I knew he was making sure I got the best possible care ~ including liaising with other colleagues for me and going above and beyond when I had a wobble. Although no one wants cancer - absolutely would recommend Panos!
Panos has been my oncologist since November 2022, when I was diagnosed with triple positive breast cancer. From the very beginning, he helped me feel calm at what was, obviously, an incredibly distressing time. Following my initial chemotherapy and surgery, residual cancer was found, which meant I needed further treatment. I then underwent 12 months of Kadcyla. Throughout this whole period, Panos has consistently supported and guided me with clarity, reassurance and care. He always takes the time to listen carefully to my list of concerns, and I really value the fact that I can talk to him about studies and research I’ve read. He never rushes these conversations and always explains things clearly and thoughtfully, which has helped me feel informed, reassured and involved in decisions about my care. I am still under his care today, attending six‑monthly check‑up appointments and receiving zoledronic acid infusions to help strengthen my bones. I would highly recommend Panos to anyone in his care.
I am so pleased from Dr Koliou's care and kindness since my original diagnosis 6 months ago. He is always there when I need him very responsive and always caring. I strongly recommend him as I cannot think of anyone else who could manage me better!
Panos is a highly experienced, knowledgeable and well respected Breast Oncologist with a varied research portfolio.
