About Us

Teamwork and experience. They are not just corporate clichés to us. It is the combination of our full and part time staff and network of preferred providers that makes York Management stand out from the rest.


Tonya York Dees, President, York Management
Since York Management opened for business in 2000, Tonya has been responsible for fundraising efforts that gathered millions for her clients, and events that have drawn tens of thousands of attendees. She is perhaps best known for her work in helping to build large-scale, multi-day events such as the IdeaFestival, which has attracted more than $5 million in fundraising and more than 30,000 attendees since its move to Louisville in 2006; and The Ryder Cup Experience, which included a week’s worth of events drawing more than 25,000 attendees. Her experience goes far beyond these signature events, however, as she has been involved in the creation of everything from charity balls, to venture capital conferences, corporate events, major training conferences and more.
