Founder and Chairman

Gregory K. Miller

Gregory K. Miller, Chairman and Founder of The Mission Essential Group, has spent his life dedicated to serving. For 16 years, he served in both reserve and active duty in the U.S. Army as a Special Forces soldier with multiple deployments in various conflict zones around the globe. It was during that time his exposure to the quality and level of service from other civilian contractors sparked the idea for the creation of Mission Essential. He instinctively knew that if he could put together the right team - with a common purpose and focus on the mission - that he could create a higher value, higher-performing support structure than he had experienced as a warfighter in-theater. In 2004, Mission Essential was born to provide top-notch Linguistic and Cultural Services to all branches of the military and other federal agencies. Today, what started as a single entity is now a multi-divisional conglomerate that continues to prospect and expand into further opportunities and customer sets.
