Will Chuchawat, 32, Partner
Sheppard Mullin Richter & Hampton

Fast facts: At age 31, Chuchawat became Sheppard Mullin's youngest partner, ever. He earned his promotion early by developing broad, cross-border expertise in mergers and acquisitions, a practice area usually built on a narrow client base. He handles deals for a wide range of businesses including large institutional and private equity clients. He is also the firm's China expert, a result of his relocation to Shanghai for two years to help grow an international, corporate practice.
