  • It was in 2009 when as a Private Patient I was under the care of Mr. Gianluca Bonanomi, who performed a Nissen Fonduplication. I was very well looked after by Mr. Bonanomi and his team and I would certainly recommend him.

  • Maybe a good idea to mend the toilet flushing system… apart from water wastage, first impressions count for a lot! Otherwise friendly and helpful staff, and punctual attendance by the consultant. Thank you. Simon

  • Outstanding care throughout. I would recommend Mr Bonanomi without hesitation for anyone requiring surgery for an inguinal hernia. But what was also extremely impressive was that he communicated with me directly both before and after the surgery.

  • Amazing surgeon with excellent people skills would not hesitate to recommend him to family and friends. I would not have trust any other surgeon do my surgery as it was a complicated procedure and Mr Bonanomi completed the surgery successfully with no complications.

  • I had inguinal hernia surgery with Prof. Bonanomi in late June. He shared in detail what to expect post surgery, and to my surprise, I had no pains whatsoever the following days. The next day I worked and did most activities from home; within 1 week fully recovered!!
