Teri Kwal Gamble and Michael W. Gamble both earned PhDs in communication from New York University. They are full professors of communication and award-winning teachers, with Teri at the College of New Rochelle and Michael at the New York Institute of Technology in Manhattan. As co-founders of Interact Training Systems, a communication consulting firm, they have conducted seminars, workshops, and short courses for numerous business and professional organizations across the United States.

The Gambles are co-authors of several textbooks and training systems, including Public Speaking in the Age of Diversity; Interpersonal Communication in Theory, Practice and Context; and Literature Alive! Their trade books include Sales Scripts That Sell, Phone Power, and The Answer Book.

Teri and Michael live in New Jersey and spend much of their time exploring how and why communication works. Their personal favorite communicators are their children—their son, Matthew Jon, who has his doctorate in biochemistry and is now a scientist, and their daughter, Lindsay Michele, who received her MBA in marketing, ran the New York City Marathon, teaches this course, and works in real estate.
