Super Lawyers Rising Stars. And he still answers his own phone.
“I am the Wolf of the Law. I have been in the room when it matters most — and I always will be.”

Top Attorneys in New Jersey — Rising Stars
New Jersey Monthly, April 2015

In the courtroom — where it counts.
Right now, somewhere in New Jersey, a business owner is staring at the ceiling at 2 AM. An HR complaint landed today. Or a lawsuit. Or an accusation — the kind that can destroy a reputation, a company, a family, before a single fact is established. That person needs one thing: the right attorney on the phone before morning. That attorney is Sean Branigan.
Sean L. Branigan is a New Jersey attorney, business operator, and legal strategist with over 20 years of experience and personal involvement in more than 10,000 successfully resolved legal matters. He has been selected as a Top Lawyer in North America three times in the last decade — one of the most exclusive peer-recognition designations in the legal profession. He has earned Super Lawyers Rising Stars honors three consecutive years and been named to NJ Monthly's Top Attorneys list. He has trained, managed, and directed dozens of attorneys. He has been in every room that matters.
His specialty — the thing that makes opposing counsel pause — is employment and labor law on both sides of the table. Over 1,000 employment and HR matters handled personally. He has represented employers building bulletproof HR systems and employees who were wrongfully terminated, harassed, retaliated against, or silenced. He knows what the other side is planning before they plan it. That asymmetry is not just an advantage — it is a weapon.
Among the most sensitive matters Sean handles are sexual harassment and sexual abuse cases — and he handles them on both sides. He has been featured in the Star-Ledger as a champion for victims' rights. He has also defended the wrongfully accused with the same ferocity — because he understands that a false accusation can be just as devastating as a real one. The falsely accused deserve a warrior too. Attorneys who can credibly, ethically, and effectively handle both sides of these cases are extraordinarily rare. Sean is one of them.
He has represented Frank Lucas, subject of the 2007 film American Gangster. He has fought for a licensed landscaper and general contractor from Montclair who was wrongly targeted by a system that assumed guilt. He is the Robin Hood of the law — and the mercenary. He takes the cases that matter, not just the ones that pay. And when he takes your case, he is all in.
Sean's background extends far beyond the courtroom. He has operated businesses, managed employees, owned real property, run landscaping and general contracting operations, and navigated the same financial, regulatory, and interpersonal pressures his clients face. He holds professional education from Harvard Business School and Harvard Medical School, is admitted to the U.S. Tax Court and Federal Courts, and is bilingual in English and Spanish. He is a YMCA lifetime fitness advocate, a financial strategist, a business broker, and a life coach. He is not just your lawyer. He is the most complete operator in your corner.
He is a rainmaker and a connector. For matters outside New Jersey or outside his direct practice areas, he refers to a trusted network of elite attorneys nationally and internationally. A $50,000 retainer is available for global matters requiring sustained strategic engagement. No matter where the problem is — Sean is the first call.
And yet — he offers a free diagnosis and strategy session to anyone who needs one. Because the first conversation should never be a barrier to getting the right advice. True victims and the wrongfully accused are never turned away for inability to pay. Paid strategic consultation is $1,000. The value of that hour will exceed anything you have ever paid for advice.
No Obligation. No Charge.
Sean welcomes a free diagnosis and strategy session with any business owner, executive, employee, landlord, contractor, or individual facing a legal challenge. You will leave with clarity — not a sales pitch.

Essex County Courthouse
Who Calls Sean
You own a business and an employee just filed an HR complaint — and you have no idea what comes next.
You were accused of something at work that did not happen, and your career and reputation are on the line.
You are a victim of sexual harassment or abuse and you need someone who will fight — not just file paperwork.
You are a landlord, developer, or contractor and a deal, a tenant, or a licensing board is threatening everything you built.
You are an executive facing a non-compete, a termination, or a board dispute and you need a trial lawyer threat in your corner.
You are a business owner who has never had a lawyer you actually trust — and you are tired of paying for advice that does not move the needle.
You are facing criminal charges and you need someone who has been in the room, knows the system, and will not back down.
You are a victim who was told your case was too hard, too complicated, or not worth pursuing. It is. Call.
What Sean Does
Over 1,000 employment and HR matters handled personally. Sean represents employers building defensible HR systems and employees who have been wrongfully terminated, harassed, or retaliated against. He has been the attorney on both sides of the same type of case — which means he knows exactly what the other side is planning before they plan it. That asymmetry wins cases.
Sean is not a settlement machine. He is a trial lawyer who prepares every case as if it is going to a jury — because that preparation is what forces favorable settlements. Opposing counsel knows his reputation. That reputation is a negotiating asset before a single motion is filed.
From residential landlord/tenant disputes to complex commercial real estate litigation, Sean brings hands-on experience as a property owner and operator. He understands the economics of development, the risk of title disputes, and the cost of getting a deal wrong. He has represented developers, contractors, landlords, and buyers across New Jersey.
Sean holds dense experience in the construction and landscaping industries — not just as a lawyer, but as an operator. He has run crews, managed contracts, navigated licensing boards, and dealt with the full range of disputes that arise in the trades. When a contractor or developer is under attack, Sean speaks the language.
Business owners and executives face a unique category of legal risk — one that keeps them up at night. HR complaints, wrongful termination claims, non-compete disputes, partnership breakdowns, regulatory investigations, and reputation attacks can arrive without warning. Sean is the domestic and international Batman for bosses who need a sure-shot mercenary in their corner.
Sean is a rainmaker and a connector. For matters outside New Jersey or outside his direct practice areas, he refers to a trusted network of elite attorneys nationally and internationally. A $50,000 retainer is available for global matters requiring sustained strategic engagement. No matter where the problem is — Sean is the first call.
