He graduated from Northern Illinois University with a bachelor of arts in the fields of speech communication and broadcast journalism. He worked for ten years in radio and television, both on-air and in sales. He took an indirect step into sales and soon realized that the selling profession was his passion. Klein began his own company in 1980 and worked with one organization achieving top sales status seven years in a row. As a manager, his firm was number one in a worldwide organization of over 2000.

Klein’s company, the Professional Development Center, has performed extensive training for such companies as Wells Fargo, Southwest Airlines, the United States Marine Corps, Chrysler, Ericsson, Nissan, Ford, Southwestern Bell, Pepsi and the Dallas Morning News. His training focuses on such key issues as relationship leadership, attitudes, team building, sales management, sales negotiation, tracking and prospecting, customer service, self (time)-management, communication skills, and cultural and behavior change. He has been a part of numerous satellite television broadcasts and expanded his operations through audio and videotapes, allowing small and medium-sized companies, as well as Fortune 500 companies, to implement his techniques.

A volunteer for Adopt-a-School, Klein is an advocate for instructing our schools how to motivate students. He has given his time, working closely with teachers and administrators, to teach leadership, time management, communication and teamwork skills. He has also given back to his profession by working with and serving as the president of the Sales & Marketing Executives of Dallas.

The diversity of Klein’s expertise, as well as his constant focus on personal development, created "Sell When You See the Whites of Their Eyes!" He’s currently writing his second and third books on the concept of Leadership vs. Management and sports trivia!
