To address his clients’ “explosive growth” and their needs for a broader swath of legal services, Silicon Valley corporate and tax lawyer Roger Royse and seven lawyers from his midsize firm are moving to the Palo Alto office of Haynes and Boone.

“The companies were getting bigger and doing more sophisticated transactions,” said Royse, who founded the 27-lawyer Royse Law Firm in 2006. Following his move, the rest of the firm will find new homes and wind down, he said.
