BRECKENRIDGE — Former Silverthorne dentist Bonifacio Guillena III, 42, of Greeley, has been sentenced to three years in prison after pleading guilty in January to possession with intent to distribute a controlled substance, a class 3 felony, according to a news release from the Fifth Judicial District Attorney’s Office.
The sentence stems from a March 30, 2018, raid at Comfort Dental on Blue River Parkway in Silverthorne, where a former employee accused Guillena of operating a “pill mill,” or illegally distributing prescription drugs, according to the release.
Silverthorne Police Department officers and federal Drug Enforcement Agency personnel raided the office on suspicion of prescription drug fraud, seizing hundreds of documents that revealed Guillena was illegally distributing prescriptions for controlled substances such as Xanax, Percocet and oxycodone as early as February 2017, according to the release.
At the time of his arrest, Guillena was on probation for domestic violence. As part of his probation, he was ordered to perform urine tests but was accused of using other people’s urine to cheat the tests, according to the release. Charges related to the fraudulent urine tests were dismissed as part of the plea agreement.
