Access Sensor Technologies was founded in Fort Collins, Colorado, in 2013. The company was spun out of Colorado State University by professors Charles Henry and John Volckens as well as a recent graduate of the Mechanical Engineering program, Daniel Miller-Lionberg. What unified these three founders was a desire to see cutting-edge technologies proliferate and become standard practice. Today, our team of five full-time employees works with consultants, manufacturing partners, and customers to develop, produce, and support high-quality products that make air sampling simple.
