During his time at GAMA, Gaddis provided leadership to a national trade association representing over 200 manufacturers of residential, commercial and industrial heating appliances, equipment and components, as well as manufacturers of equipment and providers of services used in the production, transmission and distribution of fuel gases. He helped introduce new divisions for power generation (fuel cells and microturbines), gas air conditioning and gas detectors.

Prior to joining GAMA, Gaddis ended his military career as commander of U.S. Army recruiting.

He takes over from Malcolm O'Hagan, who retired as NEMA president after 14 years. Gaddis is expected to begin work in his new position in mid-September. O'Hagan will be honored at NEMA's 79th Annual Meeting and Leadership Conference in Washington, D.C., in November.

NEMA represents the interests of electroindustry manufacturers. Founded in 1926 and headquartered near Washington, D.C., its 400 member companies manufacture products used in the generation, transmission and distribution, control, and end-use of electricity. Domestic shipments of electrical products within the NEMA scope exceed $100 billion.
