In 1977, Koren graduated from Sherman College of Chiropractic in Spartanburg, South Carolina.[5] He practiced as a chiropractor in Philadelphia,[5] and during that time helped to found the (now defunct) Pennsylvania College of Chiropractic.[6] Koren publishes brochures under the name Koren Publications, Inc. which is one of the most prolific publishers of chiropractic literature.[7] His publications cover over 60 topics related to chiropractic care,[5] with titles such as Allergies, Asthma & Emphysema, Blood Pressure, and more.[7]
In 1995, Koren was under investigation by the Federal Trade Commission (FTC) after an anonymous complaint for "false and misleading advertising".[5] Koren rewrote a number of his pamphlets as a result of the proposed FTC consent order, given to him in 1997.[1] No charges were pressed and the investigation was subsequently dropped in 2001.[5]
In 2008, the World Federation of Chiropractic (WFC) accused Koren of "serious professional misconduct" by offering seminars in the technique to non-chiropractic practitioners.[2]
Koren believes chiropractic is about more than treating back pain.[1] He believes the chiropractic method of adjusting subluxations may have positive results that range from asthma to premenstrual syndrome according to his pamphlets.[1]
