Dr. Sorenson and his wife, Vicki, developed one of the top health resorts in the world, known as National Institute of Fitness (NIF). 

During their time at NIF their clients lost over one hundred tons of fat.  

Two thirds of diabetic guests were free of all medication in less than two weeks, and many others recovered from high cholesterol, hypertension, lupus, arthritis, migraines, asthma and allergies. 

The business was consistently ranked as one of the world’s best destination health resorts. 

NIF was featured in full-page articles in the New York Times, Tokyo Times, Salt Lake Tribune, Las Vegas Review Journal, Singapore Times and other large newspapers. 

His book Megahealth was a selection of the Literary Guild and Doubleday Book Clubs.  

His current book on the health benefits of sunlight and vitamin D is called Vitamin D3 and Solar Power for Optimal Health and is being sold in Europe, Asia, Africa, Australia and Canada as well as in the U.S.
