About the Founder

Ray RhoeRay W. Rhoe, P.E., is the President of Vibration Analysts, Inc. and is ISO-certified by the Vibration Institute as a Category IV vibration analyst.

After graduating from The Citadel in 1978, Ray began working in the "Noise Review Group" at a shipyard; building and overhauling SSN-688 class nuclear attack submarines. He later took a position with a nuclear power generation company as their vibration analyst/rotating component specialist. 

Ray’s exceptional vibration test experience includes one of the largest operating deflection shape (ODS) tests ever performed in the power industry. This ODS test was performed on a 1250 megawatt Turbine Generator at a nuclear power plant and included two floors of the main turbine building.

Ray's experience also includes on-site balancing, providing ISO certification training, as well as advanced component troubleshooting and testing.

In 2000, Ray formed the PMT Group in Oglesby, Illinois. In 2006, the team began working on ReVDAP.  After completing it and recognizing its many unique benefits, Ray patented the process, incorporated the business and changed our name to Vibration Analysts, Inc. 

It's who we are and it's what we do.
