“I have known John Packard for more than 25 years. We have worked together as colleagues. He was a galvanized supplier to my company for 11 years - or longer. I watched John develop his newsletter in the early 1990's when we worked together at Pacesetter Steel Service, Inc. where he produced Galvanized Steel Update. Once John started Paragon Metal Services, Inc. it was only a matter of time before he felt the need to keep his clients informed about steel pricing, market momentum and why events were happening. His foresight saved us a lot of money and has allowed our company to grow and prosper over the years. As long as there is a steel business there needs to be a quality publication like Steel Market Update to keep the playing field level and the competition honest. .” – Earl Goode Kenwood Painted Metals
