We look forward to expanding to neighboring states, federal levels and partnering to complete the vision for Outdoor Systems Management. 

Outdoor Systems Management, LLC. (OSM) was founded June 2008 by Charles

Johnson. OSM is a Native American owned & operated company. Our specialties

began with landscaping with an emphasis on irrigation design and new construction

services. Since starting our business we have realized increased growth and


After the economic downturn OSM re-directed their services focusing mainly on

residential repair and maintenance contracts. This was due to decline demand in

designing and building new structures and properties. Instead the attention was on maintaining established landscape.

OSM was able to build a client base in the residential market which exceeded 1000 patrons whom we consider long term assets.  Our services and commitment to excellent customer services, has generated satisfied and returning customers for additional work and maintenance needs. With our countries economic improvement, we have been able to take advantage of new growth in the metro Phoenix area. With an increase in development structures and projects that are being completed each year; we expanded into commercial and light industrial service.
