Who They Are
Mark David Shirian P.C. is a New York City litigation firm founded in 2016 by attorney Mark D. Shirian, joined by Shawn D. Shirian as Senior Associate. The firm was established to represent individuals against parties with more resources and more incentive to delay, and that mission still defines how it selects and handles cases.
What They Do
The firm provides personal injury, employment discrimination, and entertainment law representation. Personal injury matters include car, truck, and motorcycle accidents, pedestrian and bicycle accidents, construction injuries, premises liability and slip and fall cases, medical malpractice, product liability, dog bites, nursing home negligence, and wrongful death claims.
How They Work
Clients work directly with an attorney rather than a case manager, from intake through resolution. The firm investigates claims early to preserve evidence such as surveillance footage, scene conditions, and witness accounts before it disappears. It identifies every responsible party in a case and builds damages using bills, wage documentation, and expert projections rather than estimates. Every case is prepared as though it will go to trial, since insurers respond to real trial risk rather than an assumption that a claimant will settle for less.
What Sets Them Apart
Representation is offered on a contingency fee basis, meaning there is no fee unless a recovery is obtained, and case evaluations are confidential and free. The firm has recovered millions of dollars for clients and combines the experience of a large firm with the attentive service of a boutique practice.
Where They Practice
The firm serves clients across Manhattan, Brooklyn, Queens, the Bronx, and Staten Island, with cases filed in New York County, Kings County, Queens County, Bronx County, and Richmond County Supreme Court. Its reach extends into Nassau County and Westchester County. The office is located at 228 East 45th Street, Suite 1700B, in Manhattan.
Recognition
Attorney Mark D. Shirian has been featured in national media outlets including the New York Times, Newsweek, and Fox News. The firm describes its approach as assertive, dependable, creative, and honest.
