Matthew Kelly began speaking at the age of 19, while he was still in college. A professor recorded a speech that Kelly gave for 50 people in his business school, and then began distributing the tapes to other interested students. Since that time, his books have been published in 25 languages, and 12 of them have appeared on the New York Times, Wall Street Journal, or USA Today best-seller lists. His speaking engagements have included travel in more than 50 countries, where he has spoken to millions of people. In 1995, Kelly became the founder of and contributor to the Matthew Kelly Foundation, a charitable organisation. He is also the founder and CEO of Floyd consulting(formerly known as Beresford Consulting) and The Dynamic Catholic Institute.
Kelly's book Rediscover Catholicism (originally published under the title Rediscovering Catholicism) has sold millions of copies worldwide. Kelly's most recent works include a children's book entitled I Know Jesus and a compilation of thoughts entitled The Long View.
In addition to his books, Kelly has produced a number of CD's and DVD's of his talks. He also consults with Fortune 500 companies as a part of Floyd Consulting and speaks at Living Every Day with Passion and Purpose events which are run through The Dynamic Catholic Institute
