In a career spanning more than 40 years, Ray has developed a rare practice combining environmental law and law concerning art and architecture. He has also played a major role in the Milwaukee and national art worlds, as well as in local government and conservation efforts.

Ray was one of the early environmental law practitioners in the 1970s and has continued his practice since that time focusing on contaminated property issues in the context of state and federal site clean ups, brownfield development, environmental insurance recovery, and contribution claims. The founder of the firm’s Climate Change practice and the leader of a sub-group focused on commercial solar developments, Ray has counseled clients, negotiated settlements, litigated cases, and lectured on a wide range of topics relating to the environment.
