The Gold professional is not interested in being hip. He feels above such colloquial activities. So, dress conservatively. Golds will tell you about themselves in the phrases they use. Third, look at his office.
Most Golds prefer the Spartan school of office decor.
They will have few photos, if any. They will not have a photo of their dog. They might have an award or a painting, but you'll find very little that gives you a glimpse into their private lives. Many Golds work every day in an office that looks vacant when they're not sitting at the desk. If there are items on the desk or in the bookshelf, they are neatly arranged and well organized.
