Rosana Kissoon, 39, has expanded her lawsuit against Long Island family physician Dr. Keith Hoerning, 51, with new medical malpractice allegations that his attorney calls a baseless shakedown.
Kissoon, a stripper who met Hoerning at her workplace in late 2024, now claims the married doctor prescribed her a cocktail of peptide shots, antidepressants, and weight-loss treatments during their roughly 18-month affair, then abandoned her without warning when she exposed the relationship to his wife.
The updated filing, submitted Oct. 28, alleges Hoerning first administered the medications in his medical office in October 2025, teaching Kissoon to inject herself with peptide shots. The treatment regimen then continued in increasingly informal settings, according to the court papers.
That treatment then continued “in a parking lot, a hotel room, and over WhatsApp — without an examination, a chart, or a fee,” the filing claimed.
The affair progressed rapidly after the pair began sleeping together in February 2025, Kissoon’s lawsuit states. By that fall, they were seeing each other several times weekly and communicating daily. Hoerning sent texts saying, “I love you,” “I will give you what you want,” and “I will find a way,” according to her initial complaint.
Hoerning, a father of two from Greenlawn, NY, allegedly promised to leave his 34-year-old wife, Nicole Hoerning, for Kissoon. But the relationship collapsed in late May when Kissoon called Nicole and revealed everything.
“When Dr. Hoerning’s illicit relationship ended, the supply and the supervision ended with it, and she was given no instruction on how to stop,” her lawyer, Michael Treanor, told The Post. “Ms. Kissoon is still dealing with the consequences, and her medical evaluation is ongoing even as Dr. Hoerning continues to maintain that he is the victim in this matter.”
“A doctor doesn’t get to set aside the standard of care because the patient is someone he’s involved with. We look forward to proving these claims in court,” Treanor added.
The abrupt cessation of treatment caused stomach problems, mood and behavioral changes, plus ongoing shoulder and chest pain, Kissoon alleges. She is currently being evaluated for potential heart issues and has been in counseling since June, the filing states.
Hoerning’s attorney, Bruce Barket, has mounted an aggressive defense, framing Kissoon’s entire legal campaign as retaliation for the end of financial support.
“We’re not going to pay a nickel to her, and at the end of the day, she’s going to find out that she picked the wrong person,” Barket said.
Barket said Hoerning kept paying Kissoon so she wouldn’t expose their affair, but “the second she realized that the payments were over, that’s exactly what she did.”
“That wasn’t good enough for her. What she decided to do then is release this stuff to the press,” the lawyer claimed.
Barket acknowledged his client’s infidelity but insisted it was the sole wrongdoing in the matter. Hoerning, “did nothing wrong other than what he obviously did wrong, which is engaging with a stripper. But that’s between him, his god, and his wife,” Barket said.
The timeline of the relationship’s final days reveals a rapid deterioration. On May 15, Hoerning sent Kissoon a cease-and-desist letter demanding she stop all contact with him and his family. Yet two days later, he allegedly messaged her a family photo. On May 24, he met her at a hotel for a peptide injection, then sent instructions for self-administering future shots with the messages “So hot! See u soon” and “Miss u already,” the new filing claims.
Two days after that, on May 26, Kissoon called Nicole Hoerning. The doctor responded by reporting Kissoon to police.
The original lawsuit, filed in June, accused Hoerning of seeking a restraining order against Kissoon after she informed his wife about their affair. Kissoon claimed this legal maneuver was an attempt to silence her and protect his reputation.
“It’s based entirely on lies, and it’s frivolous. She has no damages, nothing happened to this woman other than her gravy train stopped,” Barket said of the expanded claims.
Treanor declined to comment on Barket’s accusations against Kissoon, focusing instead on the alleged medical negligence.
Kissoon’s lawsuit continues to wind through the courts as both sides prepare for a legal confrontation over whether a doctor’s professional obligations survive the end of a secret affair.
