Russel L. O'Toole   

Mr. O’Toole began his career in communications as a central office Communications Technician for AT&T in Fort Wayne, Indiana. In 1970 Russel accepted a position as Engineering Associate in the Central Region Headquarters in Chicago, Illinois. During the next 18 years he was a specification writer and engineering troubleshooter for the installation of telephone office equipment.                   


In 1985, Russel became a first-level supervisor directing a group of engineers designing new digital central offices, pioneering some of the very first implementation of fiber optics in telephone test rooms. Later assignments included planning multi-million dollar annual Central Region construction programs.

Audio Electronics, a sound contracting firm that successfully provided cost-effective sound system installations for Houses Of Worship and schools, was started in 1972. Building his business on integrity, he also worked with a number of AM/FM broadcasters providing studio and transmitter maintenance.



Total experience in project management and construction processes uniquely qualifies R&M Consulting to provide clients with a common-sense approach to technical system and facility design resulting in projects that are completed on time and within budget constraints.
