Four patients, two of them children, are suing a west suburban chiropractor, alleging he secretly recorded them when they were undressed and receiving light therapy in private rooms.

David Hanson, owner of Hanson Family Chiropractic in Batavia, was charged this month in Kane County criminal court with multiple counts each of producing and sharing child pornography, possessing child pornography and unauthorized video recording of a minor. He remains jailed while his case is pending trial.

The civil lawsuit was filed Monday in Kane County on behalf of a mother and her two children, and the grandmother of the children.

It claims that since they became patients there in 2018, they were recorded by cameras hidden behind vents or fans that captured areas where patients were instructed to undress for red-light and near-infrared-light therapy.

More than 180 secret video recordings of patients at Hanson Family Chiropractic were made between 2017 and 2025, according to the lawsuit.

Lawyers with the Romanucci & Blandin law office, which filed the lawsuit, said additional lawsuits on behalf of other plaintiffs are expected to be filed against Hanson.

“Our legal team believes that dozens of innocent people have been harmed by inappropriate and negligent conduct at this medical office,” Sarah Raisch, an attorney with Romanucci & Blandin, said at a news conference Tuesday. “Our clients are distressed, disgusted and deeply disturbed that a predator may have violated them without their knowledge and without their consent.”

The lawsuit seeks at least $50,000 for each plaintiff on each of the eight counts alleged, which includes invasion of privacy, negligence and violation of the Illinois Consumer Fraud and Deceptive Business Practices Act.

Daisy Ayllón, another attorney, read a statement by the plaintiff identified in the lawsuit as Jane Doe 1, who is the mother of the two children in the lawsuit.

“Our family is in complete disbelief that someone we turn to for help and healing has violated us in this way,” Ayllón said, quoting the plaintiff. “And for so many members of our own family to be exploited, it raises serious concerns about how many other people have suffered the same harm. The actions of this chiropractor seriously diminish our trust in healthcare providers.”

The lawyers pointed to similarities between these allegations and claims brought against an Addison ice cream shop and its owner, accusing him of secretly recording 11 former female employees in the shop’s bathroom.

Antonio Romanucci, founding partner of the law firm which also represents the 11 former ice cream shop workers, called the use of hidden cameras in private areas a “festering problem.”

“This is a violation of trust, it is disgusting and it is damaging,” Romanucci said.

State Rep. Curtis Tarver, D-Chicago, said during the news conference that he intends to file a bill next week that aims to protect children’s civil rights in private spaces within businesses.

It would prohibit hidden cameras in places where people would expect privacy, for example, bathrooms, locker rooms and medical treatment rooms. The law would also require clear disclosure of video recording in businesses, and it would add hidden camera screening to safety inspections.
