I find Mr Gaer to be calm, professional and his extensive experience is very apparent. He dealt with any questions I had in an excellent manner, putting my mind at ease. He was not rushed and allowed time for me to express any of my concerns and responded very well. I found that the consultation was reassuring and had a motivational effect on me as I continue my recuperation.
