“Since the commencement of the Hospice we have utilised the services of William Duncan + Co Ltd and have found them to be thoroughly professional in all their dealings.  Over the years we have valued the relationship that we have together established, and have appreciated the friendly manner in which all our exchanges have been conducted. Not only have we invariably been served by the partners in a consistently helpful way, but we have noted that all the members of their staff reflect the ambience that the management has created.”
