Dr. Klein's approach is wholistic and is based upon Natural Hygiene, the world’s most successful health science program over the last 200 years. Since 1993, he has counseled over 3,000 clients back to health via his Vegan Healing Diet Plan which is based upon the principles of Natural Hygiene.

He has taught nutrition classes, given health and nutrition lectures, led many natural health seminars and produced Rawstock health festivals in northern California. Dr. Klein's own unique healing journey, his studies of many disciplines of health science, and his extensive professional experience have given him uncommon insight into the requisites of healing and health, by which he is able to consistently guide people from disease to rejuvenation.

In 1984, after suffering 8 ruinous years with advanced ulcerative colitis, Dr. Klein used the Natural Hygiene self-healing program to quickly heal his colon and rebuild his health right after the last of the 7 gastroenterologist he saw recommended surgical removal of his colon (a suggestion he rejected). He has thrived on a fruit-based, raw vegan diet with perfect colon health since 1984. Leading people to health independence is Dr. Klein's passion.
