He previously pleaded guilty to five misdemeanor counts of sexual exploitation by a medical care provider. Four additional counts were dismissed.
Johnson owned and operated Family Chiropractic Clinic of Idaho and BrainCore Therapy of Southern Idaho. He was charged in July with nine counts of sexual exploitation by a medical care provider after women came forward saying he touched them inappropriately.
In a Sept. 22 order, the Idaho State Board of Chiropractors suspended Johnson from practicing until completion of the criminal investigation.
