Mark Glies is a professional in their field. Colleagues describe them as "As a Field Application Engineer, I worked directly with Mark many times while he was District Sales Manager. Every account we visited was well qualified. It always impressed me that Mark really cared that our products were a fit for his customers, even willing to walk away when the fit was marginal. Many of those companies came back later and became loyal customers. Of course this meant that Mark really understood the technology and was able to sell its benefits. My job was to eliminate any final technical considerations, opening the door for Mark to close the sale." and "Mark is a terrific person to work with - he has a positive winning attitude and the business knowledge and expertise to close the deal. He knows how to manage and motivate people to do things that they would not normally do. He is a very talented individual and I would recommend him for any executive position."
