Simon's friendly and laid back demeanour, belies the immense skill and professionalism that he and his associates have. We were let down badly by a previous accountant and were up against it to hit certain deadlines. Simon understood the issues immediately and his swift action and advice was impressive and saved us a lot of time and money. can't recommend him any higher.... wish there was a sixth star on here.
