Veteran-Friendly. Veteran-Run.

A number of key team members at OSI are military veterans and others have worked closely with the military and Department of Defense on multi-million dollar GIS/IT projects.


Our founder and president, Greg Mader, had a 21-year military career, and was responsible for the planning and operations of a 452-soldier organization. During his Army tenure, Greg received numerous individual awards but his most valued is his Army Superior Unit Award. Ronda Mader, OSI’s Accounting principle, is a 10-year veteran of the Army Signal Corps and served with distinction both domestically and overseas.

OSI values the leadership skills, dedication, and "never quit" team attitude that military veterans bring to their job responsibilities every day. Our goal as a veteran-friendly enterprise is to assist with employment, business, and supplier opportunities for veterans, transitioning service members, disabled veterans, spouses, and veteran business owners. OSI is particularly focused on supporting veteran-owned businesses.
