I have known and worked with Ray for my duration w/ Zimmer and have found both the caliber of his work and work ethic itself to be outstanding. Together we worked on exploring new inspection and test options for our products.

Very eager, very motivated and excellent coach. During the year I worked with Ray he coached me and my team on improving our negotiation, tactical and strategic skills. He also showed his commitment by contributing his personal time and resources to improve the condition of our team, something that not everyone is willing to do. He is also a very honest person who is not shy of telling the truth when needed.
