Bio

Greg’s practice emphasizes resolving complex construction disputes through negotiation, mediation, and, when necessary,arbitration and litigation, on projects in New York, nationwide and internationally. He frequently addresses claims involving breach of contract, construction and design defects, liens, delays and impacts, bonds and insurance issues (including among others,subcontractor default insurance, general liability, builder’s risk and professional liability), and represents many of the nation’s largest contractors in building, power plant and alternative energy construction projects.

A substantial portion of Greg’s practice is devoted to troubleshooting difficult projects for clients before they devolve into full-blown disputes, seeking business solutions to his clients’ business problems. When necessary, however, he brings to bear extensive experience zealously representing clients before the courts of numerous states (often being admitted pro hac vice), federal courts, mediators, arbitration panels and appellate courts.

He regularly provides training programs at the request of construction industry organizations and clients on a wide range of topics, based on his 30 years of experience as a construction advocate, emphasizing practical guidance that project teams can implement in real time to manage risks and to avoid and win disputes.

In light of his accomplishments, Greg has for many years been recognized by Chambers USA in Construction Law (Band 1),New York Super Lawyers-Metro in Construction Litigation, The Legal 500, Who’s Who Legal, ALM Martindale Hubbard (AV Rated), and among the Best Lawyers. Greg was named “Lawyer of the Year” by Best Lawyers for construction law in New York City for 2022.

Since 2021, he is an Adjunct Professor in Columbia University’s School of Civil Engineering and Engineering Mechanics, teaching a course titled: Preventing and Resolving Complex Construction Disputes.
