Past Clients

Over the past 14 years, Nick has had the pleasure of introducing hundreds of technical staff members to data communications and networking. After all, Nick taught "TCP/IP Concepts" long before the "world wide web" was a household term and "networks" only existed in the largest of large-scale corporations. Needless to say, Nick learned far more from his audience when you consider the collective body of experience these companies represent.

AR&D is currently compiling a listing of client testimonials (brag sheet?) excerpted from letters and memos received over the years. This will be added to this page as soon as it is completed. Meantime, a sincere "thank you" goes out to all of you and your successors for being such great fans!
