Who We Are…

Optical Utility Marker (OUM) is a company owned by two individuals with over 40 years of combined utility experience.  The owners have personally dealt with the frustration of trying to locate valves and have seen the damage caused if valves cannot be shut down quickly.  They have first-hand knowledge and experience with the ease of installation and the benefits of valve markers.  Acquiring a smaller organization, Z Markers, allowed OUM to branch out and continue a steady path to growth.
