Joanne Underhill

We were exceptionally pleased with the work Joanne Underhill did for us. She analyzed the FAA regulations our business was accused of violating and helped us develop our evidence and defend ourselves. . . . Joanne … took a personal interest in our case and became our advocate.  The FAA ended up agreeing we had not done anything wrong and voluntarily dismissed its case against our company. Joanne was easy to work with and talk to. And we enjoyed working with her. Joanne works with a sense of partnership and has become a trusted legal advisor. – Rick Gulick
