My whole experience, from my initial contact with Dr Pericleous's secretary, through my procedure and follow up consultation, I have been extremely well looked after. The whole process was efficient, professional, and thorough. Dr Pericleous explained everything very clearly and gave me time to ask questions and answered them fully and clearly. Thank you.

I had the most wonderful and reassuring consultation with Dr Pericleous. He put me at my ease right from the outset. Being told that you may have cancer is a most disturbing and dispiriting experience. However, Dr Pericleous explained everything clearly and succinctly using terms that were very easy to understand.

My whole hospital experience at Royal Surrey was excellent. Dr. Pericleous kept me informed throughout my stay and ensured I knew the steps required in my treatment plan. He reached out to my previous long time consultant at a London hospital and updated me on conversations that were ongoing. I was admitted to Royal Surrey through A&E and all my medical concerns were dealt with. I liked Dr. Pericleous’s mantra -we have a plan for you -one day at a time. Thank you for the first class professionalism and expertise.

Dr Pericleous has been incredible. He spent a considerable amount of time with me to understand my concerns and was also able to provide me with onward referrals once he had resolved my initial condition. He is very easy to talk to and really takes the time to listen to all your concerns without judgment.

I have only had telephone contact with Dr. Pericleous over the past 14 months or so ,although did have a face to face meeting earlier on with a member of his team . I found Dr. Pericleous understanding and clear in his process in order to diagnose the issue I am suffering . One last MRI test planned and hopefully if all clear that should be the end of the process .

Your trust is our top concern, so providers can't pay to alter or remove reviews.
