Michael Zetlin and Michael De Chiara saw the need for a quality law firm composed of attorneys who focus on, understand, and speak the language of “design and construction”. As a result, they founded Zetlin & De Chiara in 1992. Senior Partners Ray Mellon and Carol Patterson soon came on board and, together, they built one of the premier construction law firms in the nation. Over the last 20 years, the firm has been instrumental in helping clients bring their projects to life.
