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.
