Very thorough, very thoughtful, very responsive, very caring. I am a US citizen on business in London. Found myself very ill and in need of a gastroenterologist. Found Dr Kallis on Doctify. Perfect solution. Given the unusual nature of my problem coupled with not being from the UK, Dr Kallis went the extra mile to stay on top of my case, intervene with other medical professionals on my behalf and completely make sure I was well cared for. Top notch. All the way. Highly recommended.
I saw this specialist recently, with his truly lovely specialist nurse. All my questions about a problem which had been highly concerning were answered and I left the appointment reassured and with a very clear plan of action. A huge thanks to the medical team for the excellent, thorough medical and human care.
Met Dr Kallis first time today for advice on two questions around colon screening and wellbeing. Dr Kallis offered clear and friendly advice and a good choice for next steps. Very friendly team. Thank you.
A year ago I had an operation that changed my life. Your support through it all has been amazing, for this I am eternally grateful.
Dear Dr Kallis. Thank you for your exceptionally skilful assistance today. I was left with genuinely no awareness of the procedure at all, no apparent after effects and was able to meet colleagues for lunch afterwards. I am sure that you did do the endoscopy but I have no actual knowledge of it! Many thanks.
Thank you for your second letter to my GP and copied to me. Also for explaining so carefully my digestive/metabolic status to me when we met. I felt you appreciated deeply how my experiences had left me so anxious at the slightest thing looking wrong. I am so grateful. Now I know the baseline I can keep things in perspective more easily and I feel much better. Even my hip feels a bit better, probably due to relaxation generally. Anyway I am doing more exercise. It felt a bit of an ordeal coming to such a big hepatic centre but I was very glad to be looked after by you and I wish you every success in your future career.
We would like to thank you for the care and support and is planning the treatment you provided.
Thank you all very much for taking me into your care and taking very good care me.
I really couldn't be more grateful. Thank you for giving me the hope to live...
Dear Yiannis, thank you very much for taking good care of my daughter. May God bless you and your family.
