Hanson, who pleaded guilty in September to two Class X felonies for producing and disseminating child sexual abuse material, was originally charged in a 76-count indictment. Prosecutors said he videotaped nearly 200 patients without their knowledge at his practice and distributed the recordings over the internet.

The sentence includes credit for 370 days already served. Hanson will also be required to register as a sex offender for life.

Before imposing the sentence, the judge delivered a blistering assessment of Hanson's conduct, telling the courtroom that the plea deal limited his ability to impose a longer term.

"You have proven time and time and time again, up to 188 times, that you can't walk as a free man," the judge said. "I don't know if you'll ever get out, but frankly I highly doubt if any survivors care if you do. They know you'll no longer be there in society terrorizing anyone for a long, long time."

Dozens of victims delivered impact statements during the sentencing hearing, describing years of trust built with Hanson as their chiropractor before learning of the secret recordings. Many said they had seen him for a decade or more. They spoke of a profound sense of betrayal, of difficulty trusting others, and of persistent fear that nude videos of them could surface online.

One victim called Hanson a "wolf in sheep's clothing" and said she hopes he never lays eyes on a child again. Another, who began seeing him when she was a new mother, told the court she was "sick to my stomach" when she learned what he had done.

A victim now in her early 20s testified that Hanson followed her on Instagram when she was 15 through his personal account. She said she wanted to learn from him and shadowed him at work, and that he offered her free red light therapy that she initially regarded as a kindness. Hanson told her the therapy required her to be completely naked and to stretch, she said—and while she did, he secretly recorded her.

"I spent years believing healthcare professionals are people I can trust," she told the court. "That trust has been broken. This person who was supposed to teach me is the reason I no longer want to pursue this career."

The judge praised prosecutors and the victims who spoke for their composure and courage, telling them they had nothing to be ashamed of and had acted to protect their children. After the sentence was announced, Hanson was ordered removed from the courtroom.

The case has shaken a suburban community that had long trusted Hanson as a medical provider. His practice in Batavia drew patients from across the area, and the recordings spanned years, according to prosecutors. The 60-year term ensures he will likely spend the rest of his life behind bars.
