Seyfarth Continues to Boost Corporate and Real Estate Transactional Offerings as Daniel Valsamopoulos Joins Firm as a Partner in New York

June 2, 2026 – Seyfarth Shaw LLP continues to significantly expand its transactional capabilities with the addition of Daniel Valsamopoulos as a partner in the firm’s Corporate department with extensive real estate experience. He will be based in the firm’s New York office.

Valsamopoulos brings to Seyfarth wide-ranging proficiency as a go-to transactional attorney advising private equity sponsors and public and private companies on mergers and acquisitions, investments, and general corporate matters. Clients call on Valsamopoulos for counsel on all aspects of their transactions, from inception through ultimate exit. He advises clients on sophisticated transactions spanning a wide range of sectors, including real estate, technology, health care, manufacturing, airlines, travel and leisure, chemicals, and financial services.

Valsamopoulos is the 10th lateral partner to move to Seyfarth’s Corporate department since the start of 2025. They are based in seven different Seyfarth offices, stretching across the country.

“Dan brings exceptional experience to Seyfarth with his highly accomplished track record of advising clients on complex deals in a diverse range of industries,” said Andrew Lucano, chair of Seyfarth’s Corporate department and M&A practice group. “He is the latest key addition to our Corporate team as we continue to expand our department strategically to meet our clients’ needs and goals in core markets.”

Valsamopoulos offers vast experience with a broad range of complex real estate transactions, including multi-tiered joint ventures, co-general partner and co-development partner arrangements, programmatic joint venture structures, and preferred equity investments.

“Dan’s reputation as a ‘go-to’ lawyer for real estate joint ventures for a wide range of businesses further enhances our firm’s world-class real estate offerings,” said Marc Gurell, co-managing partner of Seyfarth’s New York office. “Some of our lawyers have already worked alongside Dan and were very impressed by his ability to navigate clients to successful outcomes. We know he will be a seamless fit at Seyfarth as we continue to expand our transactional practices.”

Valsamopoulos enables sponsors, investors, and other joint venture partners to acquire, develop, and operate various classes of real estate assets in the United States and abroad. Those assets include office buildings, industrial, self-storage, health care, medical office, multi-family, mobile home, student housing, senior housing, retail, and mixed-use properties.

“Dan’s widespread experience provides a substantial bridge between Seyfarth’s Corporate and Real Estate practices,” said John Napoli, co-managing partner of Seyfarth’s New York office. “Dan is a solid and experienced M&A lawyer who can lead and support critical transactions across the platform. He also can independently and successfully handle real estate joint ventures of all types, including development transactions. We look forward to Dan playing an important, strategic role in further servicing our needs in both the real estate joint venture space as well as traditional M&A.”

Valsamopoulos comes to Seyfarth from Westerman Ball Ederer Miller Zucker & Sharfstein, LLP where he was a partner. He previously spent five years at Polsinelli as a shareholder in the corporate department focused on mergers and acquisitions and real estate joint ventures. He began his legal career in the New York office of an international law firm, where he represented private equity firms in connection with their investments, with a primary focus on distressed and special situations.

"I am thrilled to be joining Seyfarth and look forward to leveraging its national platform and the broad scope of work it offers," said Valsamopoulos. "I have had the opportunity to collaborate with the firm's lawyers on a number of matters and have always come away impressed. I welcomed this opportunity wholeheartedly and am eager to get to work with my new colleagues."

Valsamopoulos earned his JD from Brooklyn Law School and his BA from Syracuse University.
