As far as I know most big firms don't do that because its, well, kind of tacky...
E&A lists a bio on each of their attorneys. I don't see it being any more tacky than it is right now by adding one line to whomever's bio showing the person is a partner.
get serious...becoming partner @ a large firm like that is a pretty big deal, it takes education, experience and results..[
Look at Glenn's Resume - those are some major deals, some big $$$ and a good reputation for the firm.
Most people looking to advance in their profession usually go after more education. As they gain experience and get good results, they will get bigger and more important cases/jobs to handle. I'm not saying Glenn made partner right away. He's been an attorney for a long time. If new attorneys there don't see themselves advancing or see it's going to take a very long time, I think most would opt to gain some experience, develop good contacts, then move on after a few years.
After acting as counsel for BILLION dollar deals why ruin your career working as lead council for the pump & dump of the century???
One of Glenn's specialities is setting up PIPEs (ie death financing for companies unable to get funding thru regular financial institutions). As long as Glenn doesn't participate in illegal activities, I don't see how any client would ruin his career. Did Johnny Cochran's career get ruined by defending OJ Simpson? No, he became even more successful.
