Client Feedback

Client Feedback

"I work as national counsel for a large firm. Calfee assisted us as local counsel. The lawyer we worked with, Christopher Jones, had prior experience as a high-level agency employee and had great insights into the views of the agency, the state government, the attorney general and other significant parties and stakeholders in a variety of areas. He was able to assist us in meeting with the right individuals and negotiating an end to a consent decree, general advice on air permitting and compliance, and guidance on local law issues. Everything one would want in local counsel."
