At Paul Hastings, Dina Ellis Rochkind has her hands on some of the most cutting-edge regulatory issues around—cryptocurrency, financial technology and cannabis.

In January, she signed on to lobby for Paysafe Merchant Services Corp. on cannabis and related financial services issues. Just this month, Rochkind, a former aide to U.S. Sen. Pat Toomey, R-Pennsylvania, registered to lobby for the Berkeley-based Goodbit on “cryptocurrencies, blockchain and [initial coin offerings],” according to a separate filing.
