The three are based in DC. Megan Berge left the practice in March 2025.
Legal 500 Editorial commentary
Testimonials
Collated independently by Legal 500 research team.
- 'Their environmental litigation practice is without peer. They are creative, excellent on execution, practical, and service oriented. I value that they take a collaborative team approach and deliver successful outcomes. They are responsive and have seen every version of environmental-based litigation. They are not general litigators that have done one or two cases in the subject matter, they have specialists who know these high stakes arenas.'
- 'Kent Mayo is an uncommon combination of excellent service, understanding the practical realities general counsel operate within, sharp legal mind, and flawless in the courtroom. He is the general you want with you in the trenches. I am grateful to have him on our team.'
