Greg Henderson is the founder, CEO and chief visionary for Arx Pax. Greg began his career in the military as an Airborne Ranger, serving with the 101st Airborne and 7th Infantry. He graduated from West Point with a B.S in Engineering, and received a Master of Architecture degree from Berkeley. That said, what Greg succinctly envisioned with Arx Pax was a new way to employ an unexploited technology in applications that others did not see. He labeled this epiphany: Magnetic Field Architecture (MFA). Its a big dream on a one-of-a-kind technology that will change the way the world works, plays, builds and lives.
