DUCHESNE — A former boarding school nurse was sentenced to prison Thursday for sexually abusing four teenage boys.

Geary David Oakes, 57, was ordered to serve up to five years in prison for each of the four unlawful sexual activity with a minor charges he pleaded guilty to in June. Judge George Harmond also ordered Oakes to serve a one-year sentence for his guilty plea to a charge of unprofessional conduct. The sentences will run concurrently.

The victims in the four separate cases were students at Cedar Ridge Academy in Roosevelt, where Oakes was employed as director of student services for 10 years. He also served as a school nurse at the "therapeutic boarding school."

One victim's mother, in a letter to the court, said her son was a victim of sexual abuse as a young child, something that would have been noted in his file at Cedar Ridge. She said Oakes had access to that file and knew the boy was vulnerable.

"The damage done by Geary Oakes … is incalculable," the woman wrote, adding that Oakes "planted and fertilized an emotional cancer in our son."

Another parent, in a letter to the court, said his son had recently undergone surgery to repair a hernia. The man wrote that his son "tore open" his surgical incision in an attempt to draw attention to the sexual abuse he was enduring. He said the incident has been life changing for his son.

"It has made it hard for my son to develop trust with people in positions of authority," the man wrote.

Duchesne County prosecutor Grant Charles said Oakes' conduct included engaging in sexual activity with the victims, fondling them and showing them pornography. Oakes was also initially charged with providing the boys with drugs, however, those charges were dismissed as part of his plea agreement with prosecutors.

Oakes offered an apology to his victims, his former employer and his family.

"My goal is to never have another victim," he said. "I'm sorry for what happened. This will affect my life for the rest of my life."

Oakes' attorney had asked Harmond to place his client on probation and order sex offender treatment. But the judge said Oakes' conduct showed an abnormal willingness to risk his job and the strong support of his family, which demonstrated "some great compulsion that overcomes your natural caution."

"It's the lack of impulse control that makes you a risk to the community," Harmond said before imposing the prison sentences.
