Dr. William D. Danko is the co-author of “The Millionaire Next Door” with Thomas J. Stanley. He helped write that New York Times bestseller so that more people could understand what millionaires’ lifestyles are really like.

In 2007, Dr. Danko retired from the State University of New York at Albany, where he taught in the School of Business. While there, he studied how wealth forms and why consumers behave in certain ways. He presented his research all over the U.S. and in a handful of other countries as well.
