AFCEA and SIGNAL Communications Team
Meet the Staff
A dedicated and talented team based in Fairfax, Virginia, just outside of Washington, D.C., produces the variety of SIGNAL Media products, bringing to bear a combined century-plus of experience in presenting technical news in understandable and meaningful ways that matter to readers. We are a multifaceted group with diverse personal and geographical backgrounds. Some served in the U.S. military; some started careers as dancers. Some prefer PCs and others talk only Mac. We have a mix of digital natives and digital immigrants. But all care deeply about AFCEA and believe in its mission and the mission of SIGNAL Media. Pride is in our DNA.
