Excellent. Friendly and professional with very clear and comprehensive explanations of test results.
It was very positive and reassuring. Everything was explained thoroughly to me and I feel I'm in safe hands
I cannot speak highly enough of Dr Kasia. From the very first interaction, she was exceptionally kind, considerate, and empathetic. She spent nearly an hour with me on a call, which in itself was remarkable, especially compared with many private consultations where time can feel extremely limited. I never once felt rushed. What stood out most was the depth of her preparation and attention to detail. She had clearly reviewed my entire medical history thoroughly and in far more depth than any clinician I have seen previously. Her knowledge of oncology is outstanding, but what really impressed me was her ability to integrate this with a broader understanding of complex medical issues and explain everything clearly and logically. Her manner and tone were incredibly reassuring, and she demonstrated genuine sympathy and care throughout. She ensured no detail was overlooked and went above and beyond in liaising with other departments and specialists to make sure every aspect of my case was considered properly. For the first time in a long time, I felt that someone was truly in control of my care. She explained not only the current situation but also the possible future pathways, likelihoods, and risks in a way that finally made sense. Until this consultation, I had felt very much in the dark and extremely anxious due to conflicting or unclear information from other providers. After speaking with Dr Kasia, I felt informed, empowered, and significantly less anxious. I now feel completely reassured that I am in the best possible hands and that my care is being managed thoroughly and ...

It is always a pleasure to see Kasia, even under the most stressful circumstances, such as receiving scan results. I hold her in the highest esteem. She is an exceptional doctor with genuine empathy, and her care, presence, and expertise have consistently reassured me on my cancer journey. Kasia is an outstanding person who has restored my trust in Western medicine.
I was there as first appointment for SABR. Kasia explained everything showing me my scans and position of the tumor. She explained all possible complication and a rough timeline of the next steps and what would happen after treatment. She answered all my questions
Dr Owczarczyk has a lovely warm friendly manner. She explained everything thoroughly, in a clear way. I was kept well informed during my treatment. Dr Owczarczyk was easily contactable throughout, as well as arranged a number of face to face consultations.
Dr kasia was full of smiles all through my appointment with her. This Made me very relaxed about my diagnosis. She offered me her listening ears and provided all the explanations I needed which has greatly allayed all my fears. She was very professional and compassionate in her discussions with me. I left Dr kasia's office very very happy and looking forward to seeing her again.
