March 11, 2026
For Immediate Release

Tulsa, OK — Bishop Kelley High School has announced updates to the Comets softball coaching staff ahead of the 2026–2027 season, promoting Zach Postoak to Head Softball Coach and welcoming Tiffany Brown as Assistant Softball Coach.

Postoak joined the Bishop Kelley community during the 2024–2025 school year and has quickly become an important part of both the academic and athletic departments. He began as a full-time substitute teacher before transitioning midyear to teach computer literacy while also serving as an assistant coach for both the baseball and softball programs.

Before arriving at Bishop Kelley from Owasso Public Schools, Postoak taught and coached in Oklahoma at Berryhill Public Schools and Cushing Public Schools, where he served as a head baseball coach and assistant softball coach while helping lead teams to district championships and postseason appearances. He also spent time coaching at Northwestern Oklahoma State University, where he earned his Bachelor of Science in Health and Sports Science.

“Zach has been a tremendous addition to our community,” said Bishop Kelley Athletic Director Lance Parks. “He’s already built strong relationships with our student-athletes and brings the energy, knowledge, leadership, and commitment we want leading our programs.”

Postoak expressed enthusiasm about the opportunity to lead the Comets saying, “I’m grateful for the opportunity to lead the Bishop Kelley softball program,” Postoak said. “This is a special community, and I’m excited to work with these student-athletes to continue building a program defined by hard work, teamwork, and pride in representing Bishop Kelley.”

In addition to his role with softball, Postoak also currently serves as the Interim Head Baseball Coach after stepping into the position earlier this school year.

Joining Postoak on the staff will be Tiffany Brown, who brings an accomplished collegiate playing background along with coaching and teaching experience.

A native of Catoosa, Oklahoma, Brown played at Pittsburg State University, where she established herself as one of the most dynamic offensive players in program history. 

During her time with the Gorillas, Brown earned All-America honors and produced one of the most prolific offensive seasons in school history, hitting .452 while recording 90 hits, scoring 65 runs, and stealing 49 bases. Her performance ranked among the national leaders in multiple offensive categories at the NCAA Division II level.

Known for her speed, versatility, and competitive approach, Brown will assist with player development, game preparation, and continuing to build a competitive softball program at Bishop Kelley.

Brown currently serves as a health, nutrition, and physical education teacher in Catoosa Public Schools, where she also coaches softball and soccer at the middle school and high school levels. At Bishop Kelley, she will assist with physical education classes and the Blessed Stanley Rother Program for Academic Support.

“We are excited to welcome Tiffany to Bishop Kelley and the softball program,” Parks said. “She has a great playing background at Pitt State along with valuable coaching experience at the high school level. She will make a tremendous impact on our athletes and our program.”

Together, Postoak and Brown will lead the Comets softball program into the 2026–2027 season with a focus on developing student-athletes who compete with excellence, leadership, and character.
