An East Tennessee doctor from White Bluff has surrendered his license to practice medicine in the state and is the subject of an ongoing investigation involving the deaths of two patients. Although his practice was located in Copperhill near the Georgia line, 72-year-old Dr. Richard Adler is listed as having an address in White Bluff on the Tennessee Department of Health’s website. Adler was indicted on 85 counts of over-prescribing controlled substances by a federal grand jury in Chattanooga in 2010. Two of those counts include actions that contributed to the deaths of two patients identified only by their initials in the indictments. He was arrested in February 2011. Since then, Adler’s licenses to practice medicine were suspended in Tennessee, Georgia and Pennsylvania, where he received his Bachelor of Science in 1963 and Ph.D. in 1969 from the University of Pennsylvania and his medical degree in 1976 from Hahnemann Medical College. The Tennessee Department of Health’s Board of Medical Examiners reported last month that Adler voluntarily surrendered his license Nov. 20. He is prohibited from reapplying for a license for a minimum of two years and until the pending criminal charges against him are resolved. He was assessed a civil penalty for costs not to exceed $50,000. The same monthly Department of Health report on licensure actions includes the revocation of the Licensed Practical Nurse license held by Kyla M. Dunn of White Bluff for unprofessional conduct, the revocation of the Pharmacy Technician license held by Crystal L. Dagnan of Dickson for removing controlled substances from the pharmacy at Rite Aid without authorization and a $775 civil penalty assessed against Licensed Massage Therapist Donnia Gale Thompson of Dickson for failing to maintain required continuing education units.
