Derek Lax grew up in Philadelphia, a city populated by the blue-collar working class. His father was an influential figure in the Philadelphia publishing industry, but it was his aunt, the head of the Delaware County Social Security Disability and Welfare Administration, from whom he developed aspirations for a legal career. Her stories of the struggles many Americans face due to unemployment struck a nerve in Derek, who aspired to seek benefits for those without a voice.
Energized by such unfortunate stories of injustice, Derek enrolled in law school and began to work for the Fair Housing Clinic, advocating on behalf of people who could not afford public housing. He was awarded 7-11 certification, allowing him to work his way through law school representing indigent clients on various issues, including lost wages and public housing settlements.
