John Lesinski: The Godfather of I-81 | Marines, Brokerage & Reinvention What does it take to build a great brokerage career, reinvent yourself, and stay relevant for more than 40 years? John Lesinski, Vice Chairman at Colliers, has done all three. A retired Marine Corps Colonel, former Grubb & Ellis brokerage executive, entrepreneur, and one of Northern Virginia's most respected industrial brokers, John has followed a career path that's anything but conventional. He started in commercial real estate in 1985, cold-calling Northern Virginia tenants while carrying a substantial draw. He went on to become a successful producer and eventually led Grubb & Ellis's Washington, D.C. operations, overseeing one of the company's most productive brokerage teams. Then came an unexpected career setback. After losing his leadership position, John decided to reinvent himself. He left the Washington office market, launched his own brokerage firm, and bet on the future of industrial real estate along Virginia's I-81 corridor. It wasn't easy. His new venture launched just as the Great Recession was beginning. But his conviction about the market ultimately paid off, earning him a reputation as “The Godfather of I-81.” In this episode of The Great Broker Podcast, John and host David Houck discuss: From the Marines to brokerage: How military discipline helped John survive the difficult early years of commercial real estate.Building a powerhouse brokerage team: Lessons from leading Grubb & Ellis's Washington, D.C. operations and what separates great producers from great brokerage managers.Getting fired and starting over: How an unexpected setback led John to launch his own company and reinvent himself as an industrial broker.The I-81 opportunity: Why John recognized the Shenandoah Valley's industrial potential years before the market took off.The evolution of industrial real estate: E-commerce, modern distribution facilities, and how AI-driven data center demand is reshaping Northern Virginia's industrial landscape.What makes a great broker: The importance of specialization, adaptability, mentorship, and relationships that endure for decades.A life beyond brokerage: Flying, sailing, rowing, public service, and John's longstanding commitment to supporting military veterans.John also shares the story behind a complex industrial development in Winchester, Virginia, and explains why, after several attempts to pursue other interests, he keeps coming back to commercial real estate. And in the Lightning Round, we discover that a former Marine Corps aviator who owns his own airplane would still choose sailing over flying. Four decades. Multiple careers. One enduring lesson: Great brokers never stop learning, adapting, or building relationships. 🎙️ The Great Broker Podcast — Real Brokers. Real Stories.
