SHELTON — A woman visited a Shelton medical clinic just one time for immunotherapy testing, but the facility billed Medicaid for 92 appointments totaling about $14,670, according to arrest warrants.
Another patient of that same clinic, Advanced Pain and Regenerative Medical Solutions Corporation, told investigators that a tall, blonde woman, whom the patient assumed was a doctor, performed a prick test and told her she had mild allergies to cats, mosquitoes and grass, the warrants say. She received one shot, but the clinic billed Medicaid for 66 appointments totaling about $10,220, investigators said.

From Feb. 26, 2024 through Oct. 1, 2025, a forensic investigator found the clinic charged the government program meant to insure low-income people for about 4,000 fraudulent claims totaling approximately $660,000, the warrants say. The state Division of Criminal Justice found that services were either not performed, or done by an unsupervised, unqualified person, according to an agency news release.
Last Wednesday, the Office of the Chief State’s Attorney’s Medicaid Fraud Control Unit arrested clinic owner David Waltzer, 62, of East Haven; treasurer Eid J. Atallah, 61, of Middlebury; human resources and office manager Terry L. Choszczyk, 65, of Seymour; and Kimberly Choszczyk, 38, of Ansonia, who treated patients without a medical license, according to arrest warrants.
The four face charges of first-degree larceny by defrauding a public community, health insurance fraud, violation of license requirements, conspiracy to commit first-degree larceny by defrauding a public community, conspiracy to commit health insurance fraud and conspiracy to commit violation of license requirements. Each was released on a $100,000 bond and all are scheduled to appear at state Superior Court in Derby on Friday, according to court records.

Kimberly Choszczyk, Terry Choszczyk’s daughter who is also known as Kimberly Castillo, performed allergy testing, mixed allergy medications and administered allergy shots — all without a required medical license, according to the arrest warrants.
Dr. Jody L. Terranova, chief medical officer for the state Department of Public Health, told investigators that details of the investigation “scared her,” the warrants say. Terranova said Kimberly Choszczyk’s unlicensed actions “could place a patient in a life-threatening position if one is not properly trained,” according to the arrest warrants.
All four suspects, the warrants say, “had a legal obligation to submit accurate claims, avoid false statements, and report known or suspected Medicaid fraud.”

No attorneys for the suspects were listed in online court records. A lawyer listed is in the arrest warrant as representing Terry Choszczyk, but could not be reached Sunday.
Waltzer, the warrants say, “deflected any responsibility for what was occurring at his medical practice.”
“He stated he ‘delegated responsibilities to people that were skilled and trusted, to the best of my knowledge,’ ” the warrants say.
Asked about her credentials, Kimberly Choszczyk told investigators she “was certified” by Stallergenes Greer, a global biopharmaceutical company specializing in allergen immunotherapy, the warrants say. Asked if Greer gave her the authority to administer allergy shots, Choszczyk “responded yes but also admitted she was not a Medical Assistant or Licensed Practical Nurse in the state of CT,” the warrants say.

“She commented she had the training and the work experience,” the warrants say.
Atallah told investigators that he was “heavily in debt with APRM Solutions and financially struggling,” the warrants say.
“During the interview, it was observed that Atallah attempted to distance himself from the concerns brought up, stating he didn’t know what was going on,” the warrants say.

Investigators’ attempts to interview Terry Choszczyk were unsuccessful, according to the warrants.
