I engaged Margaret McCallister at Perkins Coie to navigate a challenging environmental compliance issue for our manufacturing facility in the DC area. The situation involved potential violations related to stormwater discharge permits, and the regulatory landscape was daunting. Margaret’s deep knowledge of Environmental Law was immediately apparent. She efficiently dissected the technical reports and agency correspondence, providing a clear, strategic path forward that balanced regulatory obligations with our operational realities. Her recognition by Best Lawyers in this field was well-earned and gave us significant confidence. Margaret and her team were thorough, drafting precise communications with the relevant agencies and negotiating a favorable resolution that avoided costly penalties. The one area where our experience could have been slightly improved was in the initial response time to some emails; during particularly busy periods, there was occasionally a day's delay before we received a reply. However, once engaged, her attention to detail and command of the subject matter were exceptional. I would not hesitate to recommend her for sophisticated environmental or general practice matters in the Washington, DC region.
