Mr Crinnion was very thorough in his explanations and made clear about the diagnosis and procedures. The operation was smooth and I have had no complications since the operation. Thank you Mr. Crinnion excellent service.
From my initial consultation, through the operation itself, and during my post-operative follow-up, the standard of care was consistently excellent. Mr. Crinnion’s knowledge, professionalism, and expertise inspired confidence from the very beginning. What stood out most was his manner with patients. He always took the time to listen, answer my questions thoroughly and explain every aspect of the procedure and recovery in detail. I never felt rushed and I always left appointments feeling reassured and fully informed. His calm, approachable and caring nature made what could have been an anxious experience feel manageable and positive. The operation was extremely well organised and the care I received before, during, and after the procedure was exemplary. My recovery has progressed exactly as explained, which is a testament to the quality of the advice and treatment I received. Mr. Crinnion's combination of exceptional clinical expertise, excellent communication and genuine compassion made the entire experience first class. Thank you to Mr. Crinnion and the whole team for providing such outstanding care.

I recently had my follow up appointment after surgery with Mr Crinnion, and I couldn’t be happier with the care I received throughout my treatment. From my initial consultation to the surgery and every follow up visit, he was professional, knowledgeable, kind, and reassuring. He always took the time to explain everything clearly, answer my questions, and make me feel confident in my recovery. The surgery was a great success, and thanks to his expertise and excellent care, my recovery has gone very well. I am incredibly grateful for his dedication and compassion and would highly recommend Mr Crinnion to anyone needing specialist surgical care.
Operation was explained clearly to me, performed very well & I was home in the evening. All staff very friendly & helpful. One comment I would suggest is a quick visit to my wife in the private room to give her a progress report on my op after an hour & a half would have pleased her.
Excellent consultation - gentle, friendly manner, clear communication and shared all options. Answered all my question sufficiently. Very happy.
First class. I felt myself to be in excellent hands throughout and I was not mistaken. Professional, very experienced and clearly very good at his job, but approachable and friendly at all times.
