Thomas A. Sirianni, Esq. is a Long Island attorney with over 27 years of experience representing homeowners, landlords, property owners, and lawful firearm owners across Nassau County and Suffolk County. Admitted to the New York State Bar in 1999 after earning his Juris Doctor from Touro Law Center (Jacob D. Fuchsberg Law Center) in 1998, Mr. Sirianni has handled thousands of matters in Nassau County Supreme Court, Suffolk County Supreme Court, Nassau District Court, and Suffolk District Court.
Unlike volume law firms where clients are handed off to paralegals or junior associates, Mr. Sirianni personally handles every case from initial consultation through resolution. Clients work directly with him — they get his cell phone number, they get answers within one business day, and they never wonder who is actually fighting for them in court.
Foreclosure Defense
Mr. Sirianni represents Long Island homeowners facing foreclosure under New York's judicial foreclosure system. His foreclosure practice focuses on procedural defense — challenging compliance with RPAPL § 1304 (90-day pre-foreclosure notices), RPAPL § 1306 (filing requirements), and CPLR 3408 (mandatory settlement conferences). When lenders fail to meet these statutory requirements, cases get dismissed. He has helped homeowners stop foreclosure sales, negotiate loan modifications, and navigate the settlement conference process across Nassau and Suffolk County Supreme Courts.
Landlord-Tenant Law
Mr. Sirianni represents Long Island landlords in residential and commercial eviction proceedings, holdover cases, and non-payment matters in Nassau District Court and Suffolk District Court. He understands the procedural compliance requirements imposed by the Housing Stability and Tenant Protection Act of 2019 (HSTPA) — including 14-day rent demands, proper notice service, and the technical requirements that, if missed, can cost a landlord months of lost rent. His clients range from small property owners with one rental unit to landlords managing multiple Long Island properties.
Real Estate Law
Mr. Sirianni handles residential and commercial real estate transactions across Long Island, including purchases, sales, refinances, and contract negotiations. As a real estate closing attorney, he protects buyers and sellers through every stage — from contract review through closing — and represents clients in disputes involving title issues, contract breaches, and post-closing matters.
Firearms & Second Amendment
Mr. Sirianni represents lawful firearm owners and applicants across Nassau and Suffolk County in pistol permit applications, pistol permit appeals, and Second Amendment matters. His firearms practice operates against the backdrop of New York's evolving regulatory landscape following the Supreme Court's decision in New York State Rifle & Pistol Association v. Bruen, the Concealed Carry Improvement Act (CCIA), and the SAFE Act. He has represented clients in license denials, license revocations, and matters before Nassau and Suffolk County licensing authorities.
Beyond the practice areas above, Tom also handles many other types of cases — including estate planning, personal injury, criminal defense, business and commercial matters, and family law.
