On November 15, 1993, a 71-year-old man stepped up to the line in a local gymnasium and sunk 2,750 free throws in a row. He walked away without a miss -- they were closing the gym and asked him to leave.

This amazing feat, which took 12 hours to accomplish, was witnessed by 10 people who submitted sworn affidavits to the Guinness Book of Records. The record was accepted by Guinness and he is now listed as the greatest free throw shooter of all time.

This remarkable man is Dr. Tom Amberry, known as the "Big Kahuna of Free Throws."

Dr. Tom, now 81, coaches college and high school players and gives motivational speeches to national corporations and civic groups. He has had "shoot outs" against NBA players and has never lost. He has appeared on many local and national TV shows including "David Letterman" and "NBC Nightly News."

So, what’s his secret?
"Focus and concentration," says Dr. Tom. "When I’m shooting a free throw, I don’t think of anything else. I am 100% positive I will make the basket. Never have a negative thought on the free throw line."

Are there other important aspects to free throw shooting? "It’s important to have the right mechanics. Once you learn to put your body in the proper position and shoot correctly, then the rest is mental."

Dr. Tom’s method is clearly described in his book Free Throw; 7 Steps to Success at the Free Throw Line, published by HarperCollins. He has also produced a 20 minute training video "Make Every Free Throw."

As a college player, Dr. Tom was twice All-American and the nation’s high scorer. His plan to become a professional basketball player was interrupted by World War II. He spent four years in the U.S. Navy. Later, he was offered a two-year no-cut contract with the Lakers but turned it down to become a podiatrist.

Dr. Tom shoots 500 free throws every day in a gym in Orange County, California. He shoots with a 99.5 percent accuracy.
