Tracy Mayne possesses expertise in health economics, outcomes research, pharmaceutical industry, epidemiology, biostatistics and 15 more skills. Colleagues describe them as "I worked with Dr. Mayne at Covance when he led the GHEOR group as I lead his PRO group. Tracy is quite simply one of the best leaders any of us can hope to come across. He is inspirational, visionary beyond belief, a virtuoso presenter, and a pleasure to work with on a daily basis. Tracy’s psychology expertise guides his leadership with tons of positive reinforcement, clear and objective directions, and even when correcting problems he finds a way to inspire for the future. He knows about every aspect of GHEOR and often offered to help step in on daily work when our deliverable needs exceeded our current staffing. He is also brilliant when working with startup clients, understanding the keys to demonstrating value for either goal: expand or sell. The best thing I can say about Tracy is that his leadership style inspired me to readily change my interactions with reports, many of whom commented on the positive and perceptible difference. I fully and without any reservation endorse Tracy for all of his leadership activities. "
