I had an amazingly good experience with Dr Humpries. Everything went smoothly and was dealt with quickly. My tests were run very quickly and thoroughly and my diagnosis was shared within days to allow the treatment to start. I cannot tell you how grateful I am for the care of Dr Humphries and his wonderful team.

Dr Humphries performed a colonoscopy on me yesterday for removal of a large polyp. I needed a GA and both he and the anaesthetist at St Marks could not have been more caring and professional and with clear explanations of the risks and the procedure itself etc. Dr Humphries came highly recommended and I was not disappointed.

I was referred to Dr Humphries after a positive FIT test and could not have been in better hands. From the initial consultation through to the colonoscopy itself, he was calm, clear and meticulous — taking the time to explain what would happen, what the findings meant, and what the next steps were. The procedure went smoothly, several small polyps were identified and removed, and the written follow-up letter explaining the histology arrived within days. A special mention also goes to his secretary, Kristina, who was efficient, friendly and on top of every detail — appointment confirmations, paperwork and correspondence were all handled seamlessly, which makes a real difference when you're navigating something like this. Everything was joined-up, professional and easy to follow. Highly recommended.

Dr Adam Humphries is sincerely the best Doctor I have ever encountered. I am told to be extremely particular, by my wife, and colleagues. Yet, there was not a single thing that I questioned in the process of my treatment by Adam. His professionalism, calm nature, ability to explain complex matters in simplified ways & his extraordinary skill with highly specialised machinery, was truly impressive! I could not have asked for a better Doctor during this challenging time for me. The treatment went perfectly and it has completely improved my daily life. I highly recommend Adam to anyone with concerned about possible IBS / IBD / colorectal cancer. I am left feeling grateful and quite honestly, very Impressed. Absolutely excellent.

I can only praise Dr. Adam Humprhies. All my interactions with him, from consultations to treatments, have been superb. He has endless patience, excellent bedside manner, and impressive breadth of knowledge. He's calm, collected, straight-talking, and supportive. He put me at ease at once, and I felt I was in very competent hands indeed. I highly recommend him. Not least, his private secretary, Ms. Cervenanska, is wonderful. She is helpful, quick to respond, and generally the epitome of efficiency. Thank you both.

My consultation and treatment with Dr. Humpries has been superb, form start to finish. From first consultation, coming as a patient from another consultant, through the colonoscopy and post procedure results follow up, Dr. Humphries was always extremely kind, taking all the time needed to hear my concerns and address all questions I had, and has always put me at ease, explaining things in a clear and calm manner, leaving no stone unturned regards treatment options and making me feel reassured after the procedures done. I have no words to express my gratitude to him, and all his team of assistants, nurses, and his exceptional PA, Kristina Cervenanska, who has been outstanding, on helping me arranging things in such short notice, from day one. Thank you all, for your compassionate manners, and your commitment to provide excellent care to all your patients. I'm lucky to be oe of them, Thank you!
