Here is the blurb from his profile in the 2012 edition:
Michael. Aigen is an ordained minister and one of the founding partners of Lackey Hershman, LLP. Although Michael's a licensed attorney in Texas, he is more known for his accomplishments as a dungeon master (DM) in Advanced Dungeons & Dragons. His in-depth knowledge of the Monster Manual combined with deft handling of polyhedral dice has earned him a reputation as a demanding but just DM. Recently, he has built on this experience and developed a cult following as a LARP game master, where he has enjoyed being outside.
But wait, there's more. Here is the blurb from 2011:
Michael Aigen is one of the founding partners of Lackey Hershman, LLP, a national complex commercial litigation firm. He has first-chaired jury trials in state and federal court and argued before the United States Court of Appeals for the Fifth Circuit and the Dallas Court of Appeals. He is kind of a big deal. People know him. He is very important. He has many leather-bound books and his apartment smells of rich mahogany.And, lest you think I'm just pulling your leg about his profiles in Rising Stars, here's his photo from Lackey Hershman's website.
Congratulations, Michael, you are a big deal!
