Having completed my urological training in north London I was appointed as a consultant urological surgeon at the Royal Free Hospital in 2011. I have a sub-specialist interest in endourology including the treatment of kidney stones though covering the full breadth of adult urological conditions. I offer the highest quality of urological care with the patient as my central focus. All of my investigations and treatments take into account best practice guidelines and the patient's wishes. Getting the correct result stems from individualising care.

He is a great Doctor and I am glad I have him looking after my health. I would recommend Dr. Allen to anyone and everyone. I like information, and the doctor was very good about explaining what was going on.
