In just the past few months, Usana Health Sciences (NASDAQ: USNA) has had more scandals surrounding biographical errors than any company or organization that I can think of. Take a look:

• Denis Waitley, a director at the company, decided not to stand for re-election after investigator Barry Minkow uncovered that the PhD listed in his biography came from a long-defunct diploma mill. He also does not possess a Master's degree, although one was reported in numerous SEC filings.
• Dr. Timothy Wood, Vice President of Research and Development at the company, claimed to have a PhD in biology, but it's actually in forestry, which seems less relevant at a company that makes nutritional supplements.
• Myron Wentz, the company's founder and Chairman, renounced his U.S. citizenship to "move" to the tax haven of Lichtenstein.
• And now, according to the Wall Street Journal, (subscription required), Dr. Ladd McNamara has left the company's medical advisory board after it was discovered that he no longer has a medical license. A Usana spokesman said that McNamara surrendered his license in Georgia in 2004 in response to allegations that he improperly prescribed medication to a family member. He also agreed to a lifetime ban from practicing medicine in Ohio.
