Simons care and expertese is the best I’ve ever encountered , He made sure I knew all the infomation prior to the operation. The care leading up, during and after the op was amazing! For the few days I was in hospital following my op Simon visited me regularly, something I’ve never experienced or heard of before! He is a lovely caring, kind, professional man who I can not recommend enough!!

I recently had surgery performed by Mr Monkhouse for a sliding hiatus hernia, which had been causing me severe discomfort for a number of months. It is now 5 weeks post op and I although I am still on a restricted diet, I feel like I have had a new lease of life. Mr Monkhouse explains everything in great detail in a way that you can understand if you are not medically trained, he listens to your explanation of your symptoms and then advises of the best way forward i.e. tests etc.

My experience of Mr Simon Monkhouse and his team has been an absolute pleasure, he has kept me informed (in Layman’s terms) at every step of the procedure and his reassuring manner and confidence has always made me feel that his approach was reliable and trustworthy.

Written by a patient at East Surrey Hospital

From my initial consultation I felt totally informed and relaxed about my procedure.The whole process was handled very professionally from start to finish, I felt I could contact Mr Monkhouse at any time with any worries or concerns I had after my procedure. I called him on New Years Eve (of all days) with a concern – he called me back within 30 minutes and totally reassured me. I Would highly recommend him

Written by a patient at Spire Gatwick Park Hospital

A great level of care provided. The procedure was explained very thoroughly. He answered all of our questions. He showed great patience and empathy at all times. The operation was a success, my recovery was quick and there were no complications. I would thoroughly recommend Mr Monkhouse.

@ZaherToumi @BurnKathryn @vikkirand @AbdTahrani @Mpmok @dr_yitkagraham Forcing people to do research (like trainees writing papers etc) can lead to a tick box culture and sun optimal research outcomes. I think it’s good that only low numbers do- those are the ones who have passion and will produce good results. Focus on empowering the few imho
