Dr. Mark Hoffman Abuse Investigation: Information for Patients and Families
Patients and families of Dr. Mark Hoffman, a longtime Long Island oncologist, are facing difficult questions after his arrest on charges that he sexually abused a patient during an oncology appointment in New Hyde Park.
PCVA Law represents survivors of Dr. Hoffman and is pursuing claims on their behalf. We continue to hear from former patients, family members, medical staff, and others who may have information about his conduct.
According to the Nassau County Police Department, Dr. Hoffman was arrested on March 5, 2026, and charged with second-degree sexual abuse and forcible touching in connection with an alleged incident involving a 48-year-old patient at Optum Hematology Oncology in New Hyde Park. Police have publicly asked anyone who believes they may have been victimized to come forward.
These are allegations. Dr. Hoffman has pleaded not guilty and is presumed innocent unless and until proven guilty in a court of law.
If you or a loved one was a patient of Dr. Hoffman and experienced inappropriate touching, an unnecessary or sexualized examination, or any other conduct that may have been sexually abusive, you may have a legal claim.
Why this page exists
This page is intended to be a central information hub for patients of Dr. Hoffman and their families, including former patients, family members, witnesses, nurses, and other medical staff who may have information about his conduct.
As more information becomes public, many people are asking the same questions:
- Was what happened to me or my loved one inappropriate?
- Did other patients report concerns before?
- Could Optum, Northwell, or another institution be responsible?
- Why did Dr. Hoffman leave his practice, and where did he go?
- What should I do if I think this happened to me?
- Can I still bring a claim, and how long do I have?
PCVA Law represents survivors of Dr. Hoffman and is pursuing claims on their behalf. We continue to hear from former patients, family members, and medical staff, and we are investigating whether the institutions that employed or credentialed Dr. Hoffman failed to act on warning signs about his conduct.
What are the allegations against Dr. Mark Hoffman?
According to the Nassau County Police Department, the arrest followed an investigation by the department’s Special Victims Squad. Police allege that on May 9, 2025, at approximately noon, during a routine oncology appointment at Optum Hematology Oncology at 2800 Marcus Avenue in New Hyde Park, Dr. Hoffman had unwanted sexual contact with a 48-year-old female patient. According to investigators, the doctor and the patient were alone in the examination room, and no nurse or chaperone was present.
Dr. Hoffman was arrested on March 5, 2026, and charged with sexual abuse in the second degree and forcible touching under Article 130 of the New York Penal Law. According to court records reported by local media, he pleaded not guilty at his arraignment that same day at Nassau County First District Court in Hempstead, the court issued a temporary order of protection, and bail was set at $10,000 cash, $20,000 insured bond, or $50,000 partially secured surety bond.
A spokesperson for Optum has stated that Dr. Hoffman has not been employed with Optum Medical Care since the summer of 2025.
Because the criminal investigation is described by police as ongoing, and because police have asked additional potential victims to come forward, the scope of this matter may continue to develop.
Who is Dr. Mark Hoffman?
According to publicly available professional profiles, Dr. Mark Hoffman is a 71-year-old hematologist and oncologist who resides in Roslyn, New York. He reportedly earned his medical degree from McGill University Faculty of Medicine and has decades of experience in practice. Public directories list board certifications in areas including medical oncology, hematology, internal medicine, and pathology.
Dr. Hoffman has been affiliated with several hospitals over his career, including Long Island Jewish Medical Center and North Shore University Hospital, both part of the Northwell Health network, as well as facilities outside New York. As of his arrest, a review of publicly available licensing records did not show disciplinary actions listed against his medical license.
Questions about Dr. Hoffman's departure from his practice
One issue this matter raises is the circumstances of Dr. Hoffman’s departure from the New Hyde Park practice. Public patient reviews from 2025, posted before the arrest became public, show patients asking where Dr. Hoffman had gone after he stopped seeing patients at the New Hyde Park location. In at least one review, a patient described being told their appointment was canceled but said they were not given a reason or a forwarding location.
When patients are not told why a physician has left a practice, it can raise patient-safety questions, particularly if the physician may have continued treating patients elsewhere. An important question is what the institutions involved knew, when they knew it, and what they told patients.

The institutional responsibility question
In cases like this, the question is not only what the individual physician is accused of doing. The question is also what the hospitals, medical groups, and corporate owners that employed or credentialed him knew or should have known, and what steps they took to protect patients.
Hospitals, medical practices, and healthcare companies have a duty to protect patients from abuse by their own staff. That duty includes careful hiring and vetting, supervision, clear procedures for reporting suspected abuse, and chaperone policies during sensitive examinations.
PCVA Law is investigating:
- Whether any complaints or concerns about Dr. Hoffman were reported before the criminal investigation, and how they were handled
- Whether chaperone or supervision policies existed and were followed during examinations
- Whether the institutions that employed or credentialed Dr. Hoffman ignored red flags
- Whether patients were properly notified when Dr. Hoffman left the practice and when concerns became known
- Whether Dr. Hoffman continued treating patients at other locations after concerns arose
Doctor sexual abuse cases often follow a pattern
PCVA has significant experience representing survivors of sexual abuse and misconduct by medical professionals, including cases where doctors or nurses used their position of trust to gain access to vulnerable patients and sexually abuse and exploit them.
The allegations involving Palouse appear to follow a pattern our attorneys have seen before: a respected medical provider, trusted by children and parents, is accused of using that trust to create opportunities to sexually abuse the patient. PCVA Law represented dozens of former patients of Dr. Reginald Archibald and Dr. Darius Paduch, and currently represents more than one hundred survivors who allege they were abused by Dr. Mark Mulholland in Eastern Washington. Our team understands how these cases often expand as survivors, parents, staff, and witnesses begin connecting the dots and begin to understand how the doctor used medical care as a guise for abusing them.
In cases involving medical professionals, the question is not only what the doctor did. The question is also what hospitals, clinics, medical groups, supervisors, chaperones, nurses, administrators, and other institutions knew or should have known about the doctor – and what steps they took, if any, to prevent the doctor from abusing their patients.
What to do if you were a patient of Dr. Hoffman
If you or a loved one was treated by Dr. Hoffman, you have options. You do not need to be certain you have a case before reaching out. A conversation with an attorney can help you understand whether what happened may be legally significant.
It may help to write down anything you remember, including:
- The approximate dates and the location where you were treated
- The clinic, hospital, or office where appointments occurred
- Whether a nurse, chaperone, or family member was present
- Whether you were asked to undress, and whether there was a clear medical reason
- What type of examination occurred
- Whether anything felt unnecessary, confusing, or sexualized
- Whether you or a family member reported concerns, and how anyone responded
You may also want to preserve records, including appointment history, patient portal messages, billing records, letters, emails, text messages, and notes that could help establish when and where you were treated.
If you believe you may have been a victim, Nassau County police have asked that you contact Nassau County Crime Stoppers at 1-800-244-TIPS or the Special Victims Squad at 516-573-4022. Callers may remain anonymous. You can also speak with an attorney confidentially about your civil options.
Time limits and your right to bring a claim
A civil case is separate from the criminal case and operates under a different standard of proof. You can pursue a civil claim whether or not there is a criminal conviction.
The deadline to bring a civil claim depends on the facts, including when and where the conduct occurred. Recent claims are generally well within New York’s filing deadlines, and New York has at times revived older claims that would otherwise have expired. Because these rules are detailed and can change, the most reliable way to learn your options is to speak with an attorney who can evaluate your specific situation.

Can I bring a civil claim even though there is a criminal case?
Yes. A civil claim is separate from the criminal case and operates under a different standard of proof. A civil case can result in compensation for the harm you suffered, regardless of the outcome of the criminal proceeding.
Can I keep my identity private?
In many cases, yes. Courts often allow survivors of sexual abuse to file using a pseudonym, such as Jane Doe or John Doe, to protect their privacy. It may also be possible to resolve a matter privately without filing a public lawsuit. Our attorneys can discuss options for protecting your identity during a free, confidential consultation.
What if I am not sure whether what happened was abuse?
That is common, especially in a medical setting where patients may be told conduct was part of an examination. Unwanted sexual contact by a medical professional is never a part of appropriate care. An attorney can help evaluate whether an examination was medically necessary, including through the use of expert witnesses.
How long do I have to bring a claim?
Deadlines depend on the facts and on where and when the conduct occurred. Because time limits can be strict and New York's rules in this area have changed over time, it is important to speak with an attorney as soon as possible to understand the deadline that applies to you.
Do I have to talk to police before calling a lawyer?
No. You can speak with an attorney confidentially first. A lawyer can help you understand your options, including whether and how to report to law enforcement.
