Bryan Mosca represents clients facing federal and state government investigations and other complex civil litigation in a variety of industries. He regularly assists clients involved in visible and high-stakes matters and advises them in inquiries and investigations initiated by State Attorneys General (AG) in virtually every state across a host of issues including consumer protection, environment, data privacy and security, employment and gaming. 

In addition to advising major and well-known companies in investigations, litigation and other forms of negotiations, Bryan has extensive experience advising clients on proactive compliance with statutes and regulations. Given the growing prevalence of compliance obligations accompanying orders and settlements, Bryan also assists clients after a resolution has been reached. He guides them through the stipulated compliance requirements and helps implement a variety of remedial measures that ensure future business practices meet the requirements outlined by state and federal authorities.

His clients include companies in disruptive technologies and other recently regulated areas, such as fantasy sports and multi-level marketing, and he advises them on complying with and successfully navigating a quickly evolving and increasingly onerous regulatory landscape.

Bryan began his career as a law clerk for Judge Jillyn K. Schulze of the U.S. District Court for the District of Maryland from 2010 to 2011. While in law school, Bryan studied comparative business law at the Central University of Finance and Economics in Beijing, China.
