About

The Sales Professor website is dedicated and sales professionals and managers to bring the latest news, information and insights into the minds of prospects, customers, consumers and sales staff.  This site features material not published in previous works and publications and is a way for the SPAN Consulting Group to present new material and concepts that may appear in upcoming or recent articles, books, or revisions for current catalog offerings.   There is no set duration for which pieces will appear so drop by frequently and see what’s happening in the world of understanding human behavior in business, relationships, and politics.  But no worries…if you miss an article, check out the archives to see what you’ve missed.
Sales Professor is operated by The SPAN Consulting Group, which is the recognized world leader in sales, business, management, and political psychology consulting.  It is also the home of the Paradaptive Intelligence Theory, a model that is so powerful that is able to describe all business, consumer, employee, and political behavior and is able to bring multiple sciences into one cohesive model for human decision making and behavior.  For a full abstract of the model and the scientific research it is founded upon, please go to spanconsultinggroup.com.
