Litigation Attorney | Mar 06
Relationship: Worked together on matter
"Lou and I were co-counsel on a case two years ago. He was highly professional -- and I can't think of a higher compliment in our business. He was an excellent listener for our client, and he functioned very well with opposing counsel. Lou is an example of what all lawyers should be like."
