Singleton focuses her practice on guiding clients through the intersection of business and government.

Clients – such as global businesses and trade associations – value Singleton’s extensive relationships and international development experience on Capitol Hill. She helps clients from multiple industry sectors – including international trade, transportation, energy and healthcare – navigate federal contracts, regulatory work and government affairs.

After helping draft legislation that created the U.S. African Development Foundation (USADF), a government agency that supports African-led community growth through the provision of seed capital and technical support, Singleton served for a decade as an advisory board member of USADF. In 1996, then President, Bill Clinton, appointed Singleton as General Counsel of the U.S. Agency for International Development (USAID). During her five-year tenure, she was the chief legal advisor to 72 U.S. missions around the world. Singleton was also appointed by the governor as the Secretary to the Virginia State Board of Elections.

Singleton now enjoys lending her deep government experience and proven collaborative skills to assist clients seeking to resolve regulatory or public policy issues at the national level.
