Prior to joining the firm, Melissa spent nearly 10 years in private practice at other New York and Florida law firms. She has built a reputation for successfully handling white-collar criminal matters and regulatory investigations.

During law school, she worked as a law clerk in the U.S. Attorney’s Office in Miami, Florida, in the Narcotics Division.
