About The Firm

About the Firm

History and Future

Guida, Slavich & Flores, P.C. was established in 1991 by Joe Guida and Jean Flores following their tenure at a major Dallas law firm where Mr. Guida was Coordinator of the firm's Energy and Environmental Section and Ms. Flores was a senior associate in that section.  The following year, John Slavich, with extensive environmental and related business experience, joined the firm from another major Texas law firm. 

Together, they formed the nucleus of a firm destined to be a premier institution dedicated to the singular mission of providing businesses with high quality legal services cenetered on environmental law and regulation.  These services, which have been performed in a wide array of industrial and commercial settings, have encompassed assistance in the fields of air and water quality, waste management, environmental remedation, administrative enforcement, and brownfield redevelopment.  From the start, the firm has been dedicated to assisting clients balance their business and environmental goals.

In August 2023, after well over forty (40) years of legal practice, Joe Guida and John Slavich retired from their law practices and from the firm.  Jean Flores, a founding shareholder in the firm, will continue the firm's environmental practice and continue to build on the legacy accomplishments of Guida and Slavich and the other disintinguished former shareholders and attorneys who have been a part of the firm's enterprise since 1991.
