A Word from Our Founders

Tammy York Day & Tonya York 

When we founded the Unbridled Charitable Foundation in 2012, our vision was simple, yet ambitious: to harness the excitement and energy of one of the world’s greatest sporting traditions, the Kentucky Derby, to spotlight and support worthy causes, and bring a spotlight to Louisville for economic vibrancy.  

Over the past twelve years, we’ve been able to help raise over $5 million for more than 45 important charities with the help of our amazing planning committee and partners. We’ve forged lifelong friendships, elevated powerful missions, and created moments that have left lasting impressions—not just on our beneficiaries, but on each of you, our cherished Unbridled family. 

As we look to the future, we recognize that we are entering a new and exciting chapter fueled by growth, innovation, and a bold commitment to doing more, giving more, and reaching more.

Expanding Unbridled

We’re excited to announce that we are in discussions to expand our event calendar beyond Derby weekend with: 

  • A potential return of the Derby Prelude Party to Beverly Hills in January. 
  • Unbridled Revelry as a new party the Thursday before Derby. 

Each of these events would build on our proven model, merging elegance, entertainment, and philanthropy while expanding our presence across the country. 

Sponsorships as Partnerships 

Our sponsor partners are the life blood of Unbridled. We offer flexible levels to suit brands that shares our passion for meaningful, luxurious philanthropy. The pinnacle of this is the Triple Crown Sponsorship, a $500,000 commitment for those who want unparalleled access and engagement.

If you know a person or organization that would benefit from sponsor engagement, we invite you to connect them with us. This is a community, and your introductions help us grow our collective impact. 

A Digital Refresh 

We’ve launched a new website: a fresh, immersive platform that reflects Unbridled excellence. We invite you to explore it. 

Our Gratitude 

Unbridled would not be possible without you—our guests, partners, donors, sponsors, and tireless volunteers. Thank you!

With your continued support, we will accomplish even more in the next decade. Let’s live Unbridled. Together. 

With heartfelt gratitude, 
Tammy & Tonya
