Outdoor Systems Management, LLC (OSM), Founded in 2008 is a limited liability construction company registered in the state of Arizona. OSM is solely owned by Charles Johnson, an active member of the Choctaw Nation of Oklahoma. His experience in the power industry successfully designing, building, and commissioning seven combined cycle projects and one HDPI plant has afforded Mr. Johnson the ability to work intimately with owners, banks, engineers, and subcontractors representing all trades and across the nation. This experience has given Mr. Johnson a strong ability to anticipate and account for many obstacles unique to each and every project, plan for their effect, and move a project through completion on time and budget.

In 2017 OSM brought David Steelfox on board to be VP of Construction Services in support of Mr. Johnson’s decision to begin serving the public and federal markets. Mr. Steelfox brings 37 years of experience from the power industry acting as Project Manager and QA/QC manager. His experience ranges from Hydro-Electric Dams, Combined Cycle, Nuclear Energy, Solar Generation, as well as infrastructure, such as International Airports and High-Rise Hotels along the Vegas Strip. His diverse and extensive background in Construction Management and Quality Assurance ensures OSM’s product is one of dependability and accuracy.
