Corporate and transactional attorney David Weiss has spent more than 25 years helping emerging and established companies, their boards, their owners, and their management teams throughout all stages of their life-cycle, from formation and capital raising, to growth through acquisitions and joint ventures, and to exit/sale transactions.

With substantial experience in the middle market, David has managed complex dynamics in hundreds of deals. He represents a broad client base of buyers, sellers, privately and publicly held companies, investors, and executives. 

Many of his transactions involve representing private equity portfolio companies in acquisitions or representing private companies or their management teams in their sales to private equity-backed purchasers.

Clients value the practical, problem-solving mindset that David brings to transactions, as well as his responsiveness, his ability to get complex deals done efficiently and effectively, and his ability to convey to clients complex and sophisticated transactions, and their components, in a clear and practical manner. He works closely with clients to understand their business needs and objectives and then structures and negotiates transactions to meet their goals.
