Bishop Kelley High School Names Alumna Hannah Gilliard Sipes ’04 as Director of Philanthropy

April 14, 2026
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.

Bishop Kelley Welcomes Rev. Joshua Votruba as Chaplain

April 10, 2026
FOR IMMEDIATE RELEASE Tulsa, OK— The Diocese of Tulsa and Eastern Oklahoma has announced that Rev. Joshua Votruba will serve as Chaplain of Bishop Kelley High School beginning July 1, 2026. Ordained to the priesthood on June 25, 2021, Fr. Joshua currently serves as Parochial Vicar at Holy Family Cathedral and as Master of Ceremonies for Divine Liturgies for the Diocese. Growing up in Tulsa most of his life, Fr. Joshua is a graduate of Union High School and studied Philosophy and Letters at the University of Dallas before completing his seminary formation at Saint Meinrad Seminary and School of Theology, where he graduated in 2021. His home parish is the Church of St. Benedict in Broken Arrow. Fr. Joshua’s vocation to the priesthood began at a young age through his experience serving at Mass and witnessing the joy of bringing others into the Church. That early encounter grew into a deep desire to help others know Christ more personally, a mission that continues to shape his priesthood today. In addition to his parish and diocesan responsibilities, Fr. Joshua has experience working with young people through catechetical programs such as Totus Tuus, where he taught and mentored students in both classroom and small group settings. As Bishop Kelley’s Chaplain, Fr. Joshua will play a central role in the spiritual life of the school, supporting students, faculty, and staff through the celebration of the sacraments, daily prayer, and ongoing faith formation. We are grateful for the faithful service of our current Chaplain, Fr. Jon Fincher, whose care for our students and community over the past three years has been a true blessing. “We look forward to welcoming Fr. Joshua to our school community,” said BK Principal Jim Franz. “His love for the Faith and his desire to bring others into a deeper relationship with Christ will be a blessing to Bishop Kelley. At the same time, we are also greatly appreciative of the excellent work Fr. Fincher did during his time at Bishop Kelley.” Please join us in welcoming Fr. Joshua to Bishop Kelley.
