“Dr. Jay Greenstein has provided a number of outstanding presentations during our annual safety awareness campaigns and health fairs! We consistently receive positive feedback from attendees. Employees are impressed with these presentations in part due to Dr. Jay’s knowledge and in part due to his interactive presentation style. Many of our employees, as in the general population, have had some type of musculoskeletal issues, and have been appreciative of the chance to learn and apply the knowledge they come away with from the presentations. Thank you Dr. Jay!” – Jeff from NASA
