10 Best Health Care Lawyers in New Hyde Park, NY

This guide covers 10 law firms with health care practices that serve New Hyde Park and the surrounding Nassau County area, from a firm headquartered in New Hyde Park itself to larger Long Island and statewide practices in Garden City, Lake Success, Uniondale, Jericho and Melville. Firms were evaluated on the credentials and background of their health care attorneys, the depth of their experience in provider-side work such as physician licensing defense, Medicare and Medicaid audits, regulatory compliance and practice transactions, and whether health care is a dedicated focus or one of many general practice areas.

When comparing options, three questions matter most. Does the firm regularly handle the regulator you are facing, such as the New York State Office of Professional Medical Conduct (OPMC) or the Office of the Medicaid Inspector General? Does the team include lawyers who have worked inside the health care system, as in-house counsel, compliance officers or prosecutors, and so understand how a matter looks from the other side? And does the firm handle the parallel tracks that often come with one problem, such as a licensing proceeding alongside an audit or a hospital privileges dispute?

1. Weiss Zarett Brofman Sonnenklar & Levy, P.C.

• Attorneys/Key Figures: David A. Zarett (Founding Member); Mathew Jason Levy (Principal)
• Headquarters: 3333 New Hyde Park Road, Suite 211, New Hyde Park, NY 11042
• Phone: (516) 627-7000
• Website: weisszarett.com
• Practice Areas: Healthcare Law (Physician Representation, Medicare/Medicaid Audits, OPMC/OPD Proceedings, Medical Staff Privileging Disputes), Business/Corporate Law, Employment Law, Litigation, Estate Planning, Real Estate Law, Bankruptcy
• Firm Size: Boutique, described by its founding member as a 10-attorney firm representing physicians and their practices; serves New York, New Jersey and Pennsylvania

About the Firm: Weiss Zarett is the one firm on this list headquartered in New Hyde Park. David A. Zarett is a founding member and has spent more than 30 years representing health care providers in state and federal courts, arbitration proceedings and before administrative bodies. He regularly represents physicians in disputes with academic and teaching hospitals and medical centers, has handled federal antitrust issues tied to health care business arrangements, and co-authored the chapter on hospital medical staff membership and privileges in the Legal Manual for New York Physicians, a joint publication of the New York State Bar Association’s Health Law Section and the Medical Society of the State of New York. He was named to the New York Metro Super Lawyers list from 2013 to 2016.

Principal Mathew Jason Levy handles the regulatory side of the practice, including defense of physicians and physician assistants before OPMC and of other licensed health care professionals before the Office of Professional Discipline, along with insurance audits and compliance advice. He has presented to physician audiences on how to avoid retrospective audits. The firm’s focus on physicians and their practices means its transactional work, from practice acquisitions by hospitals to employment agreement negotiations and the business structure between physicians and facilities such as ambulatory surgery centers, sits alongside its disciplinary and audit defense under one roof.

2. Garfunkel Wild, P.C.

• Headquarters: 900 Stewart Avenue, 4th Floor, Garden City, NY 11530 (additional offices in Albany, NY; Hackensack, NJ; Stamford, CT; Washington, DC; Fort Lauderdale, FL)
• Phone: (516) 393-2200
• Website: garfunkelwild.com
• Practice Areas: Health care transactions, regulatory and compliance, litigation, managed care contracting, health care information technology, telemedicine, long-term care, physician law, investigations and audits
• Firm Size: Large, 90+ attorneys across six offices, founded more than 40 years ago

About the Firm: Garfunkel Wild was founded more than 40 years ago for a single purpose, serving the legal and business needs of health care clients, and it describes itself as one of the largest law firms in the country specializing exclusively in health care. The firm reports having advised more than 100 hospitals and health systems, 500 long-term care providers, 4,000 physicians, 50 ambulatory surgery centers and 40+ Federally Qualified Health Centers.

What sets the firm apart is the professional background of its lawyers. Its attorneys include former physicians, nurses, risk managers, prosecutors, regulators and in-house counsel, which helps on matters where a clinical or operational understanding changes the legal analysis. A firm of this size is built around institutional clients, so a solo practitioner with a single matter may want to ask who will handle the file day to day.

3. Abrams Fensterman, LLP

• Attorneys/Key Figures: Howard Fensterman (Managing Partner and Co-Founder); Patrick Formato (Executive Partner, Director of the Health Law Practice); Jordan Fensterman (Executive Partner, Director of OPMC and OPD Defense)
• Headquarters: 3 Dakota Drive, Suite 300, Lake Success, NY 11042 (additional offices in Brooklyn, White Plains, Rochester, Albany and Manhattan)
• Phone: (516) 328-2300
• Website: abramslaw.com
• Practice Areas: Health Care Law, Health Care Fraud and Regulatory Enforcement, Health Care Litigation, Health Care Mergers and Acquisitions, Managed Care, OPMC and OPD Defense, Mental Health Law, Elder Law, Matrimonial and Family Law, Corporate, Labor and Employment, Real Estate
• Firm Size: Large full-service firm; Lake Success office is the Long Island headquarters

About the Firm: Abrams Fensterman began in 1999 when the Lake Success firm of Robert Abrams merged with Fensterman and Fensterman, with Howard Fensterman as managing partner. Its health care practice is recognized as Tier 1 in Health Care Law for Long Island in the Best Law Firms rankings. Patrick Formato directs the Health Law practice and has been selected for The Best Lawyers in America in health care law since 2020. He is a past chairman of the Nassau County Bar Association’s Health and Hospital Committee and has presented on fraud and abuse, corporate compliance, reimbursement and provider contracting.

The firm is especially deep on professional discipline. Jordan Fensterman, promoted to Executive Partner in January 2026, directs its OPMC and OPD defense work for physicians, nurses, dentists, pharmacists and other licensed professionals, and the firm pairs that with a health care fraud and white-collar defense group and a managed care practice. Because it is a full-service firm with offices across the state, health care is one department among many rather than the firm’s entire identity.

4. Rivkin Radler LLP

• Attorneys/Key Figures: Geoffrey R. “Jeff” Kaiser (Head of Compliance, Investigations and White Collar; Senior Counsel, Health Services); Christopher J. Kutner (Partner, Health Services)
• Headquarters: 926 RXR Plaza, West Tower, Uniondale, NY 11556
• Phone: (516) 357-3000
• Website: rivkinradler.com
• Practice Areas: Health Services, Compliance, Investigations and White Collar, Medical Malpractice Defense, Professional Liability, Insurance Coverage, Corporate, Employment and Labor, Real Estate, Trusts and Estates, Tax
• Firm Size: Large, 250+ lawyers across six offices and 23 practice areas

About the Firm: Rivkin Radler’s Health Services Practice Group is ranked by Chambers USA in the Healthcare category. Geoffrey Kaiser, recognized by Best Lawyers in Health Care Law and Litigation – Health Care, concentrates on enforcement and compliance, including health care fraud and abuse, internal investigations and matters under the False Claims Act and the Anti-Kickback Statute. Christopher Kutner represents physician groups, hospitals, managed care organizations and medical equipment suppliers, and his background includes serving as associate general counsel and later general counsel at Vytra Health Plans, where he built the company’s first corporate compliance program and served as chief compliance and privacy officer.

The firm’s health practice sits alongside a large medical malpractice defense and professional liability bench, which gives providers a single firm for regulatory and liability exposure. The trade-off of a 250-lawyer firm is that matters are typically staffed across a team rather than handled by a single partner.

5. Ruskin Moscou Faltischek, P.C.

• Attorneys/Key Figures: Jay Silverman (Health Law)
• Headquarters: 1425 RXR Plaza, East Tower, 15th Floor, Uniondale, NY 11556
• Phone: (516) 663-6600
• Website: rmfpc.com
• Practice Areas: Health Law (Regulatory, Transactional and Litigation), White Collar Crime and Investigations, Corporate and Securities, Commercial Litigation, Real Estate, Employment, Trusts and Estates
• Firm Size: Mid-size to large Long Island firm with more than 40 years of history

About the Firm: Ruskin Moscou Faltischek, a Uniondale firm with a long-standing Health Law Department, is ranked Tier 2 in Health Care Law for Long Island by Best Law Firms. Jay Silverman brings more than 25 years of private practice experience in health law, representing doctors, medical practices, independent practice associations, licensed health care professionals and facilities, health care businesses and not-for-profit organizations.

The department has historically paired health regulatory work with a white collar crime and investigations practice, so its lawyers have handled Medicare and Medicaid audits and Office of the Medicaid Inspector General matters alongside Stark Law and anti-kickback compliance and physician practice mergers and acquisitions. One of its health lawyers began his career in the Nassau and Suffolk County District Attorney’s Offices before defending providers in Medicare and Medicaid audits. Health law is one of many departments at the firm, so clients with a purely clinical-licensing matter may also look at more specialized boutiques.

6. Farrell Fritz, P.C.

• Attorneys/Key Figures: Mark R. Ustin (Partner, Chair of the NYSBA Health Law Section); Kevin P. Mulry (Partner)
• Headquarters: 400 RXR Plaza, Uniondale, NY 11556
• Phone: (516) 227-0700
• Website: farrellfritz.com
• Practice Areas: Healthcare, New York State Regulatory and Government Relations, Litigation, Real Estate, Bankruptcy, Labor and Employment, Finance and Banking, Wills, Trusts and Estate Planning
• Firm Size: Mid-size, 51 to 99 attorneys; offices on Long Island and in Albany

About the Firm: Farrell Fritz operates a dedicated New York Health Law blog and a healthcare practice that spans Long Island and the state capital. Partner Mark R. Ustin chairs the New York State Bar Association’s Health Law Section and was named to City & State New York’s 2026 Trailblazers in Healthcare list. His earlier career included health policy roles in the administration of former Governor George Pataki, and his work has included protecting nonprofit hospice care, expanding early intervention access and securing Medicaid coverage for emerging treatments.

Kevin Mulry is a commercial litigator with a health care focus who has represented clients before the Centers for Medicare and Medicaid Services and the Office of the Medicaid Inspector General. The Albany presence is a practical advantage for matters that turn on state agency policy. As with other general practice firms on this list, health care is one practice among several.

7. Moritt Hock & Hamroff LLP

• Attorneys/Key Figures: Frank A. Mazzagatti, Ph.D., Esq. (Partner, Corporate and Healthcare)
• Headquarters: 400 Garden City Plaza, Garden City, NY 11530 (additional offices in Manhattan and Fort Lauderdale)
• Phone: (516) 873-2000
• Website: moritthock.com
• Practice Areas: Healthcare, Corporate, Litigation, Real Estate, Creditors’ Rights and Bankruptcy, Trusts and Estates, Not-for-Profit, Intellectual Property
• Firm Size: 80+ attorneys; founded in 1980

About the Firm: Moritt Hock & Hamroff added healthcare as a practice area in 2006 and 2007 and is ranked Tier 3 in Health Care Law for Long Island by Best Law Firms. Its healthcare practice was strengthened in 2022 when Frank Mazzagatti joined as a partner in the Corporate and Healthcare groups. Mazzagatti represents hospitals, healthcare providers, specialty pharmacies, group practices, skilled nursing facilities, ambulatory surgery centers and office-based surgical practices on transactions, corporate compliance, regulatory law, license defense, accreditation and government and third-party audits in New York, New Jersey and the federal courts.

He teaches Health Law as an adjunct professor at Hofstra University’s Maurice A. Deane School of Law and has been a licensed respiratory therapist since 1987, a clinical background that is unusual among health care lawyers. The firm is a commercial law firm first, so its health practice draws on a corporate and transactional bench that suits practice sales, mergers and structuring work.

8. Harris Beach Murtha Cullina PLLC

• Attorneys/Key Figures: Roy W. Breitenbach (Member, leads the Health Care Industry Team)
• Headquarters: The Omni, 333 Earle Ovington Boulevard, Suite 901, Uniondale, NY 11553 (Long Island office; 17 offices across Connecticut, Massachusetts, New Jersey and New York)
• Phone: (516) 880-8484
• Website: harrisbeachmurtha.com
• Practice Areas: Health Care, Long-Term Care, Government Compliance and Investigations, Business Litigation, Real Estate, Corporate, Trusts and Estates
• Firm Size: Large, 275+ attorneys; formed in 2025 through the combination of Harris Beach PLLC and Murtha Cullina LLP

About the Firm: Harris Beach Murtha’s Long Island office is based in Uniondale. Roy Breitenbach leads the Health Care Industry Team, and a significant part of his practice involves resolving disputes with managed care companies and other third-party payers, along with business disputes, regulatory matters, employment-related litigation and patient access matters. Attorneys from the firm have also been recognized in Best Lawyers: Ones to Watch in America in Health Care Law.

The firm’s reach is regional and its health care practice includes long-term care and work for nonprofit health and human service agencies licensed by state agencies. As a 275-lawyer regional firm that only recently combined, its Long Island office is one node in a much larger network, so clients who want a single senior partner on a matter should ask who will lead it.

9. Nixon Peabody LLP

• Attorneys/Key Figures: Michele A. Masucci (Partner, Healthcare)
• Headquarters: 50 Jericho Quadrangle, Suite 300, Jericho, NY 11753 (Long Island office of a national firm)
• Phone: (516) 832-7500
• Website: nixonpeabody.com
• Practice Areas: Healthcare transactions and regulatory, private equity healthcare, accountable care and alternative delivery systems, life sciences, employment, real estate, private wealth
• Firm Size: Large national firm with a Long Island office in Jericho

Michele Masucci leads Nixon Peabody’s health care work out of the Long Island office and chaired the firm’s Healthcare Group from 2010 to 2016. A former hospital in-house counsel, she advises health care companies and middle-market private equity firms on transactions and regulatory needs, with particular experience in dermatology, dental, ophthalmology, physical therapy, infusion, dialysis and pharmacy. Chambers USA placed her in Band 1 for Healthcare in its 2023 USA guide, and Best Lawyers has recognized her in Health Care Law for Long Island.

Her recent writing addresses how federal antitrust rules and state regulation, including material change notice requirements and corporate practice of medicine rules, apply to private equity healthcare arrangements, as well as the PC-MSO model. The focus leans toward transactions and investors rather than individual physician disciplinary defense, so providers facing a licensing or audit matter may find a smaller, defense-oriented firm a closer fit.

10. Bond, Schoeneck & King PLLC

• Headquarters: 68 South Service Road, Suite 400, Melville, NY 11747 (Long Island office, combining the former Melville and Garden City offices since May 2025; firm headquartered in Syracuse)
• Website: bsk.com
• Practice Areas: Health Care, Long-Term Care, Labor and Employment, Business and Transactions, Creditors’ Rights and Bankruptcy, Litigation, Real Estate and Construction, Municipal Law
• Firm Size: Large, 300+ lawyers in 14 offices; Long Island office of 40+ attorneys

About the Firm: Bond’s health care team counsels clients across the continuum of care, including health systems, hospitals, long-term care providers, physicians and group practices, behavioral health providers, home care agencies and managed care plans. The firm built a dedicated long-term care practice group after six attorneys from Albany-based Ruffo Tabora Mainello & McKay joined, serving nursing homes, assisted living facilities and home health agencies on issues from restructuring to employee benefits. Its health care work is paired with a large labor and employment practice that represents health care employers.

The Long Island office is a smaller outpost within a statewide platform, and much of the health care bench is concentrated elsewhere in the state. For Nassau County providers, the Long Island office offers access to that broader group, particularly for employment and long-term care matters.

Frequently Asked Questions

What is OPMC, and when does a physician need a health care lawyer?

OPMC is the New York State Office of Professional Medical Conduct, which investigates complaints against physicians and physician assistants. Other licensed professionals, including dentists, nurses and pharmacists, are handled by the State Education Department’s Office of Professional Discipline (OPD). OPMC investigators are authorized to examine patient records without the patient’s consent, so a physician who receives a letter or an interview request generally benefits from counsel before responding. Firms such as Abrams Fensterman and Weiss Zarett handle both OPMC and OPD proceedings.

What is the difference between health care law and medical malpractice law?

Health care law covers the regulations and legal issues that apply to providers, patients and the health care system, including licensing, audits, billing compliance, contracts and transactions. Medical malpractice is a civil liability claim over patient care. Some firms handle both for providers, such as Rivkin Radler, which has a dedicated medical malpractice defense practice alongside its health services group, but a regulatory or licensing problem is a different type of case from a malpractice lawsuit.

What kinds of government audits and investigations do health care lawyers handle?

Providers can face reviews by Medicare, Medicaid, the Office of the Medicaid Inspector General and commercial insurers, as well as investigations involving the False Claims Act, the Anti-Kickback Statute and the Stark self-referral law. Lawyers such as Geoffrey Kaiser of Rivkin Radler concentrate on these enforcement matters, and Kevin Mulry of Farrell Fritz has represented clients before CMS and OMIG. Matters that start as a billing audit can turn into a broader investigation, which is why firms with a white collar group alongside the health practice, including Ruskin Moscou Faltischek, are often considered for them.

Should a physician practice hire a boutique firm or a large firm?

It depends on the matter. A boutique such as Weiss Zarett, a 10-attorney firm built around physicians and their practices, tends to offer direct access to senior lawyers and a focus on individual providers. Larger firms such as Garfunkel Wild (90+ attorneys) or Rivkin Radler (250+ lawyers) bring bigger benches for complex institutional matters, multi-state issues and large transactions. Ask who will personally handle the file and how often that person has handled the same type of matter.

What legal issues come up when buying, selling or investing in a medical practice in New York?

Practice sales and investments involve structuring questions such as the corporate practice of medicine rules, management services arrangements, self-referral and anti-kickback compliance, employment agreements and, in some cases, regulatory notice requirements. Attorneys such as David Zarett of Weiss Zarett have handled practice acquisitions by hospitals and health systems, Frank Mazzagatti of Moritt Hock & Hamroff advises on health care transactions and compliance, and Michele Masucci of Nixon Peabody focuses on private equity healthcare arrangements and the PC-MSO model.

Can a New Hyde Park health care lawyer handle matters outside New York?

Many can. Weiss Zarett serves clients in New York, New Jersey and Pennsylvania, Mazzagatti practices in New York and New Jersey and before the federal courts, and Garfunkel Wild states that it handles issues with a health care component anywhere in the country.
