Our company, The Internet Centre, has worked with David for many years on different projects both simple and complicated. David is arguably the most capable and informed Internet and computer network professional in Alberta. There may be other people who are just as capable, but none more capable, than David in all aspects of secure networking and operations. He and his staff have been an invaluable assistant and mentor for some of the more complicated secure networks that we, as the oldest Internet Service Provider in the Province of Alberta, have had to establish and maintain. We have received excellent feedback from customers to whom we have referred David, and he quite simply gets the job done. He is a professional, honest, and hard working individual, and we will continue to avail ourselves of his expertise and talents going forward. We would recommend him to any of our customers.
