Who We Are
       Keith Cron, CIH

Hygienix was created in 2018 by Keith Cron, a Montana native and Certified Industrial Hygienist (CIH) to provide professional industrial hygiene, environmental, and safety services related to anticipation, evaluation, design, and control of the health and sustainability of individuals and the environment utilizing the best available technology with providing enhanced environmental science-based solutions.

When Keith does not have his scientist cape donned, he enjoys spending time with his wife (Chrissy) of 20 years, his son (Colton) and daughter (Ella). Growing the Great Falls community through various 'not-for-profit' organizations has been a continuous way of life for the Cron family as well as enjoying the Big Sky country with friends and family.

       Dwight Stevenson, CIH, CSP

A native of Montana, Dwight Stevenson is a CIH and Certified Safety Professional (CSP) who attended Montana Tech.  He joins Hygienix with nearly three decades of Environmental Health and Safety (EHS) leadership and management experience in the Department of Defense (DoD) and Department of Energy (DoE) sectors.  More than a decade of Mr. Stevenson's experience was gained overseas, and Dwight recently returned to Montana from Saudi Arabia where he led the research safety efforts at a major research university on the Red Sea.  His defense related work took him to the Former Soviet Union, Australia, and the Pacific Islands while his work at Los Alamos and Idaho National Laboratories saw him supporting national defense and nuclear energy programs. 

Dwight is excited to be back in his hometown of Great Falls with his wife and their three boys. He enjoys getting outdoors, working on their family ranch along the highline and coaching his boys on the ice with Great Falls Youth Hockey. 

While Dwight has technical expertise in EHS management systems, industrial hygiene, worker safety and event investigation & response, he has found that his experience in the implementation of cultural safety programs is the key discriminator in achieving EHS excellence.
