Retirement Announcement: Doug Thomas, Bishop Kelley High School Director of Philanthropy

December 19, 2025

After 14 years of extraordinary service to Bishop Kelley High School, Doug Thomas will retire in September 2026 from his role as Director of Philanthropy.


Doug joined Bishop Kelley after serving as a Major Gifts Officer at the University of Kentucky, bringing a level of fundraising expertise rarely found at the high school level. Over the course of his tenure, his leadership has had a transformational impact on our school and our community.


During his 14 years at Bishop Kelley, Doug has helped raise nearly $55 million in support of our students and mission. Through capital campaigns alone, Doug secured more than $35 million. This includes more than $25 million raised during the most recent We Are BK capital campaign, nearly $9 million for the 2018 The Championship Drive campaign (renovation and expansion of the stadium) and nearly $1 million in 2015 for the construction of the wrestling and cheer fieldhouse.


When Doug arrived at Bishop Kelley, the school’s endowment stood at approximately $5 million. He often shares that one of his proudest accomplishments has been helping grow it to more than $20 million today.


For all who have worked with Doug, it is clear that these remarkable achievements are motivated by his deep belief in accessible Catholic education and the value he places in enduring relationships with donors, families, alumni, and friends of Bishop Kelley. His work will continue to shape opportunities for students for generations to come. We are grateful to God for the impact Doug Thomas has had on the mission of Bishop Kelley’s service to students!


In January 2026, Bishop Kelley will begin its hiring process for Doug’s successor. We ask you to join us in prayer as we seek the right person to continue this critical work and build upon the remarkable foundation Doug has established since 2012.
