Peter G. Siachos is an experienced trial lawyer and partner in the New Jersey, New York, Pennsylvania and South Carolina offices. Having taken over 60 trials to verdict, Mr. Siachos routinely handles class action and individual matters nationwide, many of which are high-exposure with media coverage, before federal and state trial and appellate courts, administrative and regulatory agencies, and arbitration panels.  

Mr. Siachos is licensed in numerous jurisdictions (New Jersey, New York, Pennsylvania, District of Columbia, and South Carolina) and utilizes creative dispositive motions, aggressive deposition tactics, well-crafted trial strategies, and focused and effective appeals to regularly assist his clients with their litigation needs in all 50 states.

Mr. Siachos has successfully litigated and tried individual and class action cases involving consumer protection claims, franchise issues, prosecution and defense of trademarks, product liability, shareholders disputes, financial institution liability, directors and officers claims, ADA accommodation (retail and website), professional liability (lawyers, accountants and design professionals), catastrophic transportation claims, sports and fitness club claims, construction claims, and employment matters, including claims regarding anti-competition, retaliation, discrimination, and harassment.

In addition to his trial experience, Mr. Siachos has handled in excess of 50 hearings seeking injunctive relief (temporary retraining orders and preliminary injunctions), including trademark, franchise, shareholder, consumer protection, and real property matters.

Representative examples of his specific expertise include the following:

Franchise Law

Mr. Siachos devotes a significant portion of his practice to the representation of franchisors. He has extensive experience litigating and enforcing franchise agreement terminations, non-competition restrictions, forum selection clauses, indemnification provisions, and liquidated damages provisions. Mr. Siachos has had repeated success in enjoining trademark infringement on behalf of his franchisor clients, and has obtained injunctive relief against franchisees in a number of jurisdictions, which ranged from enforcement of simple franchise agreement provisions to forcibly shutting down franchise locations.

Class Action Defense Including Consumer Protection Statutes

Mr. Siachos routinely defends class action litigations including, nationwide and state class claims arising under consumer protection statutes and false advertising or unfair competition statutes, including alleged violations of the TCPA (Telephone Consumer Protection Act), FDCPA (Fair Debt Collection Practices Act), and FCRA (Fair Credit Reporting Act).

Product Liability

Mr. Siachos defends clients in product liability matters and has tried nearly 20 products cases to verdict. He has represented manufacturers of automobiles, pharmaceuticals, medical devices, consumer products, and diagnostic testing equipment in product liability matters. His extensive work on automotive products and warranty litigations, coupled with his love of cars, has allowed him to gain automotive technical proficiency that has proved to be invaluable during the defense of a case.

His practice includes the handling of matters related to lender liability, including the defense of FDCPA, FCRA, TILA, and RESPA claims, commercial collections, and other matters related to lender’s rights.
