Adam’s father was an FBI agent for more than 25 years.

As a former outside counsel for a national tax preparation company, he spent many years traveling across the country to enforce the company’s restrictive covenant agreements.  In his career, he has handled hundreds of cases involving the enforcement of non-compete, non-solicitation and confidentiality agreements, including assisting clients in preventing former employees from disseminating the employer’s trade secrets.

Adam is experienced in representing clients in cases of alleged harassment, discrimination and retaliation. He also frequently assists clients with issues of OSHA compliance, inspections and resolving or contesting OSHA citations.

Throughout his career, Adam has represented and advised clients in the industry sectors of manufacturing, construction, HVAC, retail, non-profit, healthcare, restaurant and hospitality, technology, transportation, banking, and insurance. He works closely with company management, owners, human resources departments, in-house counsel, insurance adjusters, employees, and experts to accomplish clients’ litigation and business objectives, including counseling on dispute and liability avoidance techniques.
