FOUNDER / CEO
Mike Buck
Mike Buck is the CEO and Founder of Radian Advisors, bringing decades of leadership experience in private and public service. As a former senior government official, in addition to appointments to various advisory Commissions, Mike understands how to support governmental entities to obtain favorable outcomes. Advising major national and international companies and serving on multiple corporate boards gives him a deep knowledge of what it takes to advance the interests of private industry and strategic land development. Mike answered the call when he received a series of Orders from the Department of Defense to act as a civilian subject matter expert, and report overseas for national security missions in Ukraine, Poland and Romania. However, Mike says that his most interesting paid job was as a NASA test subject for deep space exploration.

Ken S.
Lt. Col., United States Army (Ret.)
“In missions of a politically and militarily sensitive nature in Ukraine, Poland and Romania, Mike Buck’s role as a civilian advisor with subject-matter expertise gave us instant credibility. I’m proud to say the success of our missions can be seen in part by the resistance of FSU [Former Soviet Union] countries to current Russian aggression. As a civilian, Mike showed his character by willingly volunteering and accepting Orders from the U.S. European Command to participate in this series of missions.”
