My first job was as a field attorney for the National Labor Relations Board (NLRB) in Houston. I had hoped to clerk for a judge, but in this hope I was disappointed. But the lessons I learned at the NLRB proved more useful in the long term, at least for me, than any I could have learned elsewhere. Here are my mentors and the lessons they taught me.
