About Us

Desert Tox was founded in March of 2017. In 2016, Southwest Laboratories, a SAMHSA certified laboratory located in Phoenix, was closed and left a gap in DOT testing in Arizona. With no SAMHSA certified laboratory located in Arizona, Desert Tox was started by two former employees of Southwest Laboratories and a client of Southwest Laboratories. It has been great serving Arizona and beyond. Desert Tox has grown quickly, but still abides by its original principles of quality work and great customer service.
