Joining Dovel & Luner
I had a good thing going at the U.S. Attorney’s Office, and was only interested in leaving if I could find another place to do righteous work with great people. Dovel & Luner is that place. Everyone at the firm cares deeply about our clients and our craft. We work on getting better every single day because that is what it takes to win cases against well-funded corporate adversaries. And while we handle complex, high stakes litigation, we are kind to one another. Those are values that resonate with me, and I’m proud to be a partner at the firm.
