POWER BROKER WINNER
CoStar Group Inc., a leading provider of commercial real estate information, analytics and online marketplaces, announced the CoStar Power Broker Quarterly Deals winners for Q2 2025. John Hannigan, principal of Choyce Peterson Inc. was recognized among Fairfield and Westchester County’s top dealmakers. The CoStar Power Broker Quarterly Deals winners are determined by the largest transactions executed each quarter, based on price and square footage. Hannigan received recognition for negotiating the 27,416-square-foot renewal of L’Amy America’s warehouse at 65 Trap Falls Road in Shelton, Connecticut, part of a broader strategy that also included securing a new 5,016-square-foot headquarters lease at 2 Corporate Drive. This achievement reflects Hannigan’s long-standing relationship with L’Amy, having represented the company in multiple relocations and renewals. Working closely with Stephen Rappoport, president of L’Amy, he identified and executed a solution that brought the office and warehouse closer together, providing convenient highway access, upgraded amenities and long-term operational efficiency.
In praising Hannigan’s leadership during the process, Rappoport said, “Once again, John proved invaluable in this complex search for office and warehouse space. He led simultaneous negotiations of two different leases with terms that contained competitive rental rates and landlord funded tenant improvement dollars. During the entire process, John demonstrated his superior market knowledge and negotiation skills and guided us on all key decisions.”
“…I am pleased that we achieved the best solution for all their space needs and the L’Amy team can now work more efficiently in their conveniently located headquarters office within two minutes of the warehouse,” said Hannigan.
