Expert Construction Counsel Who Delivers Results

Our company faced a complex, multi-party dispute over significant delays and cost overruns on a major D.C. development project. The opposing parties were aggressive, and the contractual issues were deeply entangled. We engaged Lawrence Prosen at Cozen O'Connor on a colleague's strong recommendation. From our first meeting, his 27 years of focused experience in construction law and arbitration were evident. He didn't just react to the dispute; he deconstructed the project history, the contracts, and the technical specifications to build an unassailable position. His recognition by Best Lawyers in Arbitration and Litigation - Construction is well-earned. Lawrence guided us through a strategic mediation with a commanding yet pragmatic approach, securing a settlement that not only recovered our losses but preserved critical business relationships. His professionalism is matched by his practical understanding of how construction projects actually work. He is a formidable advocate and a trusted advisor.
