Dr Mullen and his team were extremely informative and helpful. From my first enquiry and consultation, through to being discharged after the procedure, Dr Mullen put my mind at ease, explaining everything clearly and I knew I was in safe hands!
I saw Dr Mullen at short notice. He spent a lot of time going through things with me and discussed next steps. I was very reassured to be in expert hands
efficient and professional. I felt I was in very safe expert hands. From the initial consultation when Dr Mullen spent a lot of time to explain everything to me right through to the procedure it was all excellent. I would highly recommend Dr Mullen to anyone

Thankyou very much for these kind words
Surgery performed with no complications and post surgery explanations were clear and well timed.

Thankyou very much for this kind review
Very good experience. Efficient, approachable, practical.
Dr Mullen is a very professional and caring doctor. From meeting him and eventually going through my procedure he kept me well informed and assured at all times.
Dr Mullen is a true professional. That is to say, not only is he a master of his art, he explains with simplicity and clarity the procedure being undertaken, leaving his patient absolutely confident that he is in the very best of hands.
I have always found the care and explanations given by Dr Mullen to be excellent. The description of the procedures I have had under his care including the potential risks were outlined well and I felt informed of the decisions I was making. I cannot complement his professionalism and and approach to the procedures I had enough and the follow up afterwards has been excellent too.

Thank you very much for taking the time to write this review and your kind words.
I was seen very quickly and left understanding the severe news of my diagnosis, but with hope for the outcome. I am keen and confident for Dr Mullen to sort me out.
