I was impressed with the detail he discussed with me, and with the copious notes he took. His summary of the next moves he would take were clear and wholly to the point - not rushing to conclusions, but intending to find more out from the records of all relative matters which would lead him to the best advice. I look forward to working further with him to solve my 'problems'. One of the very best consultations I have had over my long life.
