Excerpt from Roush website:

Roush celebrated its 30th anniversary in 2006. What began in 1976 as Jack Roush Performance Engineering is now recognized internationally as a premier provider of automotive engineering and systems integration solutions, with over 2,500 employees in facilities across the globe.

Roush has grown significantly over the years in direct response to our customers needs. Recognizing that integrated services provide tremendous efficiency and synergy, we have strategically acquired skills and expertise in areas such as advanced composites, body design and engineering, paint and trim services, fabrication, and instrumentation. This focus has resulted in Roush’s unparalleled ability to lend support across the entire product development life cycle. 

Several key acquisitions have rounded out our product and service offerings. Our acquisition of Anatrol NVH Services, with their extensive experience in the field of mechanical noise and vibration analysis, has provided a critical component in Roush’s portfolio of comprehensive engineering services.
