Bill has experience representing real estate owners, joint ventures, developers and high-end funds that invest in real estate projects. He handles often precedent-setting litigation and arbitration involving valuation issues, the enforcement and termination of hotel management agreements (including disputes involving most of the major hotel operators), complex lease structures, development agreements, and issues of fraud and racketeering, breach of contract, fiduciary duty, accounting, cost allocations, unfair trade practices, personal services and agency.

From formulating and executing strategic plans to handling evidentiary hearings through trial and appeal, Bill helps clients across a spectrum of sectors—financial services, real estate, consumer products, technology and life sciences—navigate challenges where the amounts at stake and issues of contention have a decisive impact on the core viability and integrity of their businesses. These challenges encompass the full range of business disputes, including fraud, breach of contract, breach of fiduciary duty, valuation, misappropriation of trade secrets, non-competes and intellectual property infringement.
