Brookline, Waltham Business Owner Sentenced In $1 Million Fraud Scheme

BROOKLINE, MA — A South Korean national who owned physical therapy clinics in Brookline, Waltham and other Greater Boston Communities was sentenced to more than two years in prison late last week after he was convicted in January in submitting more than $1 million in false health care insurance bills for appointments that never took place.

Chang Goo Yoon owned the physical therapy clinics in Allston, Waltham and Brookline between 2014 and 2018. Prosecutors said he billed clients for appointments that were purported to be on days when he was traveling to South Korea, Los Angeles and Toronto and that he made more than $300,000 off the reimbursements.

Court documents said he billed $50,000 in claims on days he was gambling at the Golden Nugget
casino in Atlantic City, N.J., MGM Springfield and Twin River Casino in Lincoln, R.I. Prosecutors also said he submitted claims for himself after three car accidents in which he listed one of his employees falsely as the physical therapist, and claims in which he listed himself as his own physical therapist.

"This long-running scheme appears fueled by sheer greed," FBI Boston Special Agent in Charge Jodi Cohen said, "and the FBI and our partners are committed to bringing medial professionals lie Chang Goo Yoon, who chose to betray their oath and get involved in fraud, to justice."

Yoon was arrested and charged in February 2021 and indicted by a federal grand jury in May 2021. He was convicted of two counts of health care fraud following a seven-day jury trial and sentenced to 27 months in prison followed by three years of supervised release.
