Our Team

Richard Seaton

After working independently as a writer and consultant in the early to mid-1990s, Richard founded Impact Marketing + Communications in 1997. At the time, Impact was engaged almost exclusively with organizations addressing HIV/AIDS. But Richard believed that cause-based organizations deserved the kind of top-flight resources that for-profit entities often take for granted. In fact, he has stressed, from the beginning, that these organizations don’t need the same resources that commercial enterprises do, they need more — because people’s lives are often on the line. Since that time, the firm has expanded both in terms of the services it offers and the organizations it serves.

A native of rural Tennessee, Richard came to Washington in 1984 and then moved to Italy for a number of years where he worked in business development. Along the way, he picked up a love of all things Italian — the wine, in particular — and also the belief that life is, indeed, beautiful. Very beautiful. Today, he lives with his partner and foxhound in Washington’s Logan Circle neighborhood, but can often be spotted in the region’s airports from where he feeds his most serious addiction: travel.
