FOR IMMEDIATE RELEASE 

Tulsa, Okla. — Bishop Kelley High School is pleased to announce the appointment of alumna Hannah Gilliard Sipes ’04 as the next Director of Philanthropy. Sipes will begin her role on May 1, 2026, and will work alongside current Director of Philanthropy Doug Thomas through September, ensuring a thoughtful and seamless transition.

A native Tulsan and proud Bishop Kelley graduate, Sipes returns to her alma mater with more than a decade of strategic leadership in nonprofit fundraising and a deep commitment to mission-driven work. She earned her degree in Business Management from Oklahoma State University and has built a strong reputation across Tulsa for cultivating meaningful relationships and advancing philanthropic impact.

“As a Bishop Kelley alumna, Hannah understands firsthand the lifelong value of a Bishop Kelley Catholic education,” said Sister Mary Hanah Doak, RSM, President of Bishop Kelley High School. “Her professional experience, combined with her heart for this community, makes her uniquely positioned to lead our philanthropic efforts in service of students into the future. We are thrilled to welcome her home.”

During her time as a student at Bishop Kelley, Sipes was actively involved in theater, one-act plays, improvisation, and speech and debate. These formative experiences sparked her appreciation for communication, creativity, and community engagement.

Most recently, Sipes served as Associate Director of Advancement for Development at Cascia Hall Preparatory School. She previously held leadership roles with Global Gardens and the American Heart Association, where she focused on corporate partnerships and philanthropic growth. She is an active member of the Association of Fundraising Professionals.

Sipes will succeed Doug Thomas, who will retire in September 2026 after 14 years of extraordinary service to Bishop Kelley. The five-month overlap between Thomas and Sipes is a rare and meaningful opportunity that reflects Bishop Kelley’s commitment to continuity, stewardship, and long-term success. Together, they will work closely to ensure a smooth transition and continued momentum in advancing the school’s philanthropic priorities.

“I am honored and excited to return to Bishop Kelley in this role,” said Sipes. “This community played a significant role in shaping who I am, and I look forward to building on the strong foundation already in place to support future generations of students.”

Sipes lives in Sand Springs with her husband, James, an Army veteran, and their two daughters, who attend Marquette Catholic School. The family are parishioners at Christ the King Catholic Church. Outside of work, she enjoys spending time with her family-cheering on her daughters in their activities, and exploring national parks together.

With deep roots in the Bishop Kelley community and a clear vision for the future, Sipes will lead the school’s philanthropic efforts in support of its mission to prepare students’ hearts and minds for a purposeful life.
