Who We Are

Home / Who we are

Vizitech USA is a digital education and training company specializing in interactive 3D Technology, Augmented Reality, and Virtual Reality learning and training programs. We take complex concepts and processes and recreate them virtually for an interactive, safe learning experience. 

Vizitech President Stewart Rodeheaver, a retired U.S. Army Brigadier General, started the company after realizing the military needed a better way to train young recruits. After writing to the Army Senior Leadership, General Rodeheaver studied AR, VR, and 3D technology and discovered that these interactive learning methods absolutely focused on the “Screenagers” we were recruiting and training. Using these highly focused platforms increased training effectiveness, reduced time on task, and dramatically reduced the time and costs needed to establish new skills in our students greatly improved training outcomes. 

After several years of working exclusively on military projects, the company expanded to include education and civilian training. Today, our clients include school districts across the southeast, commercial clients, and government clients, as well as continuing to serve our nation’s military.
