About Us



The Underground Movement (TUM) offers premium apparel inspired by our past heroes and historical events – both well-known and forgotten – reminding us to be humble and inspiring us to fall back in love with America.

TUM co-founder Jason R. Beardsley, a Green Beret and Special Operations Forces veteran, brings a passion for American exceptionalism – honoring those men, women, and events that shaped our nation into the land of liberty.  Through a nod to our grand heroes who were sculpted by American values, TUM has created a brand that celebrates rugged individualism with unique graphic designs on custom T-shirts and other wearable pieces.
Jason, along with Special Operations Forces veteran and long-time friend, Gregory K. Miller, formed TUM in 2013 after more than 20 years of distinguished military service.  With the transition from “the most interesting job in the world” to entrepreneurship, Jason and Greg have combined their ability to enjoy life, sense of adventure, and creativity, with their expertise in planning and executing complex military missions, to build a company that embodies their passion for our great nation.
Often called upon by media outlets such as Fox News and CNN as an expert in the areas of counterterrorism, security and foreign events, Jason is also an advocate for veterans and advisor to Concerned Veterans for America.
