Mr Nima Abbassi-Ghadi treated me with care and professionalism from my very first visit, he explained everything in detail and made me aware of all the pro's and con's of having my surgery. On the day of the surgery he made me feel completely at ease about the operation and what was going to happen. At my 6 week follow up appointment he again treated me with professionalism and explained everything in detail once again. He is a credit to the hospital and if I needed any treatment again in the future I would be more than happy to have him as my consultant.

I was overly anxious going into my surgery as it was my first , I was also worried about the anaesthetic making me nauseous. I didn’t need to worry at all , I raised my concerns and the staff were so ,so nice and reassured me.. Recovery was very good , if it wasn’t for the obvious scaring i felt absolutely fine , no pain at all .. Thank you all again , you made my fear of surgery a pleasant experience that I didn’t need to worry myself over .
