Robert A. Manning

A native Floridian, Robert has been practicing environmental law with Hopping Green & Sams since 1994.
Robert’s practice focuses primarily on air quality-related issues, including policy development, legislation, rulemaking, permitting and enforcement. Although his practice recently has focused on issues affecting the electric utility industry, he also works for many other industrial and municipal clients, including phosphate, solid waste management, oil and gas, chemical, fuel distribution, and cement. When not practicing law, Robert enjoys outdoor adventures with friends, including mountain biking, boating, hiking and golf. In the last few years, Robert has also roamed over 50,000 miles around the country on his Harley-Davidson. Robert is also very grateful for the opportunity to give back to the community, most recently as a member of the United Way’s Community Resource Team, and as a temporary host parent for the Children’s Home Society.
