Hired in 2011, Coach Bishop has been the Head Coach at Regent Prep in Tulsa, OK since the program began. 

The Rams play a very exciting and innovative extreme tempo style and are 98-18 since joining the OSSAA, including six trips to the State Quarterfinals, four trips to the State Semifinals and two trips to the State Championship game. Over the past 14 seasons, Regent Prep has set multiple State and National records, including Highest Completion Percentage in a Season, Passing Yards in a Season, Passing Touchdowns in a Season, and Touchdown Receptions in a Career. 

Off the field, the Rams were crowned Academic State Champions in 2016 and 2019.

Coach Bishop came to Regent from Parkers Chapel High School in Arkansas, whose football program he helped begin in 2003. In the program's sixth year, the Trojans advanced to the Class 3A State Playoffs for the first time. Bishop's coaching stops also include assistant posts at Star City, Arkansas (varsity wide receivers, junior high offensive coordinator). Coach Bishop was a varsity letterman in football, basketball, and baseball at Norphlet High School in Arkansas. He graduated with a Bachelor of Science degree in education from Southern Arkansas University in 2002. 

Adam and his wife, Kelly, have three children — John David, Judson, and Owen. They reside in Bixby and are members of Evergreen Church.

Bob Mareburger joined the faculty and coaching staff at Regent in the summer of 2015. In addition to serving as an assistant coach for both varsity football and basketball, he teaches high school math, economics, personal finance, contemporary culture, and entrepreneurship.

Mr. Mareburger came to Regent after retiring as senior vice president of Tulsa-based ONEOK corporation. His nearly 30-year corporate career also included tenures with CITGO Petroleum and as a management consultant.

He is a graduate of the University of Oklahoma with a degree in Petroleum Engineering and an M.B.A. and has been recognized as a Distinguished Alumni of Price College. He is also a graduate of the Harvard Business School Advanced Management Program.

Prior to Regent, Coach Mareburger coached youth and middle school baseball and football and was a NCAA-certified high school basketball tournament team coach.

Mareburger and his wife, Diane, have been part of the Regent community since 2001 along with their two sons who are both Regent graduates.

Through his experiences coaching and working with church-based youth groups, Mareburger discovered a passion for mentoring and encouraging young people to live lives of purpose. He describes his motivation as: “Despite being blessed to work for great companies and leaders who invested in me personally, I believed God was calling me to enter a new season of life. Shortly before making a final decision to retire and make the change, I felt this calling so strongly that I believed not doing so would be disobedient to God’s plan for my life. When it became apparent that this coincided with specific needs at Regent, I knew that it was God who was opening the door. I am now equally blessed to work with an entire Regent community that cares passionately about raising a generation of students who can fulfill the unique purpose God has given to each one.”

“For we are God’s handiwork, created in Christ Jesus to do good works, which God prepared in advance for us to do.” Ephesians 2:10

Coach DeCelle has been selected as the “Teacher of the Year" at Bixby High School multiple times and comes to Regent as a very relational, accomplished and quality math teacher with years of teaching and coaching experiences in Bixby, Broken Arrow, Collinsville, and Stroud.

Coach Decelle played four years of college baseball at Southwestern University and was also a graduate assistant baseball coach at Southwestern University for two years.
