My Why
What powers my practice
I was inspired to pursue a career in law by watching my father work as an attorney and seeing the meaningful connections he built with his clients. He approached each person with genuine care, taking the time to understand not just their legal issues, but their lives and broader concerns. That ability to connect on a human level left a lasting impression on me. It showed me that practicing law is not just about legal knowledge or advocacy, but about trust, empathy, and relationships. I was drawn to building those same kinds of connections in my own career—serving clients not only as their attorney, but as someone they can rely on and feel understood by.
Overview
Matthew Sullivan advises developers, investors, lenders, and business owners on a wide range of commercial real estate transactions. His practice includes leasing, acquisitions, dispositions, and financing, and he regularly guides clients through complex deals from initial structuring through closing. He brings a practical, business-oriented approach to navigating legal frameworks, conducting due diligence, and negotiating agreements that position clients for long-term success.
His work spans multiple sectors, including restaurant and hospitality, healthcare, and retail real estate, where he represents national tenants and multi-location operators across the United States. In addition to handling leasing, development, and construction-related matters, Matthew supports clients with ongoing operational real estate needs, as well as workouts, foreclosure-related agreements, and lease dispute resolution. He also advises healthcare providers on practice acquisitions, dispositions, and real estate strategy, helping clients manage both transactional and operational considerations.
Matthew’s real estate practice is closely integrated with his corporate experience. He advises public and private companies, entrepreneurs, and growing businesses on entity formation, governance, mergers and acquisitions, and debt and equity financing, and frequently serves as outside general counsel. This dual perspective is informed by his prior role as in-house counsel for a national restaurant company, where he developed a strong understanding of the business and operational challenges clients face.
He also brings deep experience in the restaurant and hospitality industry, advising on liquor licensing, entity structuring, and national expansion strategies. His ability to connect real estate, corporate, and regulatory considerations allows him to support clients across all stages of growth
