We were very fortunate to be treated by Dr Grier when we visited the Royal London Emergency Department at the weekend. He is a highly knowledgeable and extremely competent medical professional with an engaging and reassuring manner. He made the process smooth and swift, quickly identifying the potential problem. He was attentive and focused and his diagnosis and prediction about my recovery has been spot on. The whole experience with Dr Grier and the entire team at The Royal London was, without doubt, the best encounter I have had with any medical professional.
