He was well known nationally for helping companies structure their businesses and operations to avoid inadvertently becoming investment companies, as well as to avoid registering as investment advisers, broker-dealers, commodity trading advisers, or commodity pool operators. Rob also assisted early-stage and other companies whose businesses require them to register in one or more of these capacities.

Before entering private practice, Rob worked at the Securities and Exchange Commission from 1986 to 1990, including in the Office of the General Counsel, in the Division of Corporate Finance, and as counsel to then-Commissioner Joseph A. Grundfest.
