This listing of my customers serves the dual purpose of (1) letting you see what a distinguished group they really are, and (2) to give some of them a little publicity for the business they are in. Many of them like being listed here (especially those whose links to their Web sites are shown,) and some have called to bring me up to date on changes in company names due to mergers and other matters they considered important.
