Professionally, Gary's ONE Thing is teaching. He excelled as a real estate salesperson by teaching clients how to make great home buying-and-selling decisions. As a real estate sales manager, he recruited agents through training and helped them build their careers the same way. As cofounder and chairman of the board, he built Keller Williams Realty International from a single office in Austin, Texas, to the largest real estate franchising company in the United States by using his skills as teacher, trainer, and coach. Gary defines leadership as "teaching people how to think the way they need to think so they can do what they need to do when they need to do it, so they can get what they want when they want it."An Ernst & Young Entrepreneur of the Year and finalist for Inc. Magazine's Entrepreneur of the Year, Keller is recognized as one of the most influential leaders in the real estate industry. He has also helped many small business owners and entrepreneurs find success through three nationally bestselling books: The Millionaire Real Estate Agent, The Millionaire Real Estate Investor, and SHIFT: How Top Real Estate Agents Tackle Tough Times. A book, after all, is just another way to teach, but one with an infinitely large classroom. As a business coach and national trainer, Gary has helped countless others realize extraordinary results by narrowing focus to their own ONE Thing. Unsurprising to those who know him, Gary's single greatest achievement is the life he's built with his wife Mary and their son John.
