He offers clients a deep understanding of all facets of the commercial real estate finance industry and related legal issues. Clients value John’s broad background and strategic mindset and trust him with their most important and sensitive matters.  

John represents lenders, commercial mortgage and special servicers, investors and other capital providers in a wide variety of commercial real estate finance transactions of all types involving all asset classes of commercial real estate, including loan originations, loan sales and purchases, commercial mortgage backed securities (CMBS), loan restructurings, modifications and workouts, foreclosures, and the leasing, management and sale of commercial real estate assets. In addition to partnering with clients to execute existing loan programs, John has experience in all aspects of developing and implementing bridge lending programs focused on the origination of floating rate commercial mortgage loans intended for securitization and balance sheet execution.  

A significant portion of John’s practice involves the CMBS industry and, in particular, advising commercial mortgage master and special servicers as well as CMBS investors on legal and business-impacting issues of all types - ranging from day-to-day to high-stakes decisions - with respect to loan documents, restructurings, pooling and servicing agreements, trust and servicing agreements, co-lender, intercreditor and participation agreements. He is known for his ability to adeptly identify and navigate legal risks while finding practical solutions to difficult problems.  

In addition to transactional matters involving commercial real estate finance, John works closely with Polsinelli’s Financial Services Litigation practice on matters involving litigation, bankruptcy and other disputes related to non-performing and sub-performing commercial mortgage and mezzanine loans, and with Polsinelli’s Capital Markets practice on matters involving securitization, structured finance and mortgage loan servicing rights.  

Throughout the great financial crisis and continuing for the next several years, John represented various lenders and special servicers in the successful enforcement, resolution and workout of many large, highly-structured commercial mortgage loans, including loans secured by multiple luxury hotels in the United States and Mexico and loans secured by trophy office buildings across the United States. More recently, during the COVID-19 pandemic, John has helped lenders and special servicers navigate and resolve commercial real estate loans and other assets of all sizes and types, with a specific focus on hospitality properties of all service levels and retail properties ranging from grocery-anchored centers to large regional malls.
