I write to you to commend you for the format of the reference book and the content. This has been an invaluable reference point for me, as I have joined the NHS in England, from Northern Ireland. I make regular reference to the book for address information of colleagues and suppliers e.g. Will Beck, Stryker UK Ltd, GE Medical Systems, RS components to name but a few. I would hope that this book becomes a regular (updated) item as I and my team make good use of it. I wish you continued support and success for this publication.
