“Toxic Mold” Guru (Andrew Campbell. M.D.) Surrenders Medical License

Stephen Barrett, M.D.
January 24, 2012

Andrew W. Campbell, M.D., as medical director of the Medical Center for Immune &Toxic Disorders in Spring, Texas, was prone to conclude that patients who consulted him were suffering from allergic disorders related to “toxic mold” exposure. In 2001, at a hearing held by the Texas Department of Insurance, he testified that his center was seeing 50 such patients per week. Additional information about his practices and fees were revealed in two reports by a Vaccine Court special master who denied petitions former patients who sought compensation for an alleged vaccine injury. One report indicated that Campbell had charged $12,123 for the first visit and about $47,000 more for about 16 more visits plus intravenous treatments between 1999 and 2002. The other report did not state the cost of visits in 1997 and 1998 but described fees totaling more than $30,000 between 1999 and 2002. In 2011, after more than ten years of involvement with the Texas Medical Board, Campbell surrender his medical license.

In August 2011, Campbell was charged with inappropriate treatment of eight more patients whom he had treated for chronic pain. In November 2011, the pending complaints were resolved by voluntary surrender of his medical license. The surrender order permits him to apply for reinstatement once a year. If he does, however, I doubt that he will succeed.
