Coaching Staff

Assistant Coach | John Cooper

John Cooper, a veteran of over 100 wins as a Division I head coach, has joined Mike Boynton’s staff as an assistant coach for the Oklahoma State basketball team.

A Kansas City, Missouri native, Cooper spent the previous five seasons as the head coach at Miami (Ohio), where his defense-first approach saw the RedHawks ranked among the nation’s top 50 in steals in four of his five seasons.

In all, Cooper has been in collegiate coaching since 1993, including eight seasons as a head coach, and assistant coaching stops at South Carolina, Oregon and Auburn.

“I am very excited to have a man of John Cooper’s experience and character joining the Oklahoma State basketball family,” Boynton said. “I have known him for a long time, in fact he was a member of the coaching staff that recruited me years ago, and to this day he is a tremendous mentor for young men and an outstanding basketball coach. He will bring invaluable experience to our staff, and his recruiting connections all over the country will serve us very well.”

In his five seasons with the RedHawks, Cooper helped produce five All-Mid America Conference selections, including 2017 MAC Freshman of the Year, Michael Weathers. Every RedHawk senior earned their degree, and four players went on to a career in the professional ranks.

 “When you start talking about people and what they stand for; their integrity, leadership and basketball knowledge, Mike Boynton has had all of those qualities dating back to his high school days at Bishop Loughlin,” Cooper said. “I’ve known Mike for years. We’ve stayed in touch throughout our careers, and I know what he’s about. I want to help he and Lamont Evans to do whatever we can do to represent Oklahoma State in the best way, and win basketball games, and I couldn’t be happier to be a part of the Oklahoma State family.”

Prior to his stay at Miami, Cooper served as the head coach at Tennessee State for three seasons, where he built that program into a formidable force. His 2011-12 TSU squad posted a 20-13 record, the school's first winning mark since 1995-96 and the Tigers' first 20-win season in 32 years.

Perhaps TSU's most impressive victory came on Feb. 9, 2012 when it defeated seventh-ranked Murray State, 72-68. The loss was one of just two suffered that season by the 31-2 Racers.

Cooper's team nearly earned a berth in the 2012 NCAA Tournament, losing at the hands of Murray State by a score of 54-52 in the Ohio Valley Conference Tournament final. TSU also claimed its first win over an SEC opponent in 2011-12 when the Tigers defeated South Carolina, 64-63. His three-year overall record at TSU was 43-51, including a 27-25 mark in OVC games.

Cooper was a finalist for four different coaching awards in 2011-12, including the Jim Phelan National Coach of the Year Award (national coach of the year), the John McLendon Award (top overall collegiate coach), The Hugh Durham Award (nation's top Mid-Major coach) and the Ben Jobe Award (nation's top minority coach in Division I).

Cooper joined Tennessee State following a five-year stint as associate head coach at Auburn University under Jeff Lebo. He played a vital role in the revitalization of the Tigers' basketball program with Auburn recording its first winning season since 2003. Auburn posted a 24-12 record in 2008-09, advancing to the quarterfinals of the National Invitation Tournament.

Prior to his time at Auburn, Cooper spent two seasons at Oregon where he helped the Ducks to a 41-23 mark. Oregon went 23-10 with an NCAA Tournament appearance in 2002-03 and had an 18-13 record in '03-04, losing in the NIT semifinals.

From the 1995-96 season through the 2000-01 campaign, Cooper served as an assistant coach at South Carolina. During a three-year stretch from '95-96 to '97-98, the Gamecocks posted a 66-28 record. The 1996-97 squad won the Southeastern Conference title, finishing with an overall record of 24-8 and finishing No. 6 in the national rankings.

Cooper's first coaching job was as an assistant at Fayetteville State from 1993-95.

A native of Kansas City, Mo., Cooper played collegiately at Wichita State. He led the Shockers in scoring and rebounding during his junior and senior seasons. Cooper was a two-time team captain and a Rhodes Scholar candidate in his senior year.

He played professional basketball with the Ft. Wayne Fury of the Continental Basketball Association in 1991-92 and with the Commodore Mustangs (Netherlands) in the European Professional Basketball League in 1992-93.

Cooper earned a bachelor's degree in business administration from Wichita State in 1991. He is married to the former Melissa Mathis. They have a daughter, Kennedy, and a son, Kameron.

Assistant Coach | Scott Sutton

Oklahoma State head basketball coach Mike Boynton has announced the hiring of Scott Sutton, the winningest coach in Oral Roberts history and a former Cowboy, as an assistant on his staff.

A veteran of 18 seasons as a head coach and 328 career victories, Sutton guided the Golden Eagles to eight postseason appearances, including three NCAA Tournament bids. The three-time Summit League Coach of the Year produced four Associated Press All-Americans and four conference players of the year at ORU.

“I’m thrilled to have a man of Scott Sutton’s pedigree joining our coaching staff,” Boynton said. “The Sutton name certainly means a great deal to our program and the Oklahoma State family, but it’s just as respected nationally. Scott’s name is all over the program’s record books from his playing days, and he’s proved himself in the coaching arena as well. I’m excited to welcome Scott and his family back to Stillwater to help us continue this program’s march to excellence.”

Sutton played for the Cowboys from 1992-94 under his father, the legendary Eddie Sutton. He saw action in 63 career games and is arguably the most efficient guard in program history. Sutton still holds the single season and career records for assist-to-turnover ratio thanks to a senior season that featured 119 assists and just 21 turnovers (5.67 a/to). For his career, Sutton had 181 assists to just 49 giveaways for a ratio of 3.69.
After graduating from OSU in 1995, Sutton made the short trip to Oral Roberts to serve on Bill Self’s coaching staff. After one season he was elevated from an administrative assistant role to assistant coach, where he helped the Golden Eagles pile up 57 wins over the next three seasons.

He was announced as the head coach at ORU on April 30, 1999 and wasted little time in returning the program to prominence. Sutton and the Golden Eagles fired off 14 consecutive winning seasons starting in 2001-02, which included seven 20-win campaigns and eight postseason bids.

“I’m beyond excited to join coach Boynton’s coaching staff at Oklahoma State,” Sutton said. “OSU is a special place for my family, and we are thrilled to come home to Stillwater. I look forward to helping coach Boynton and the Cowboys continue to have great success.”

After finishing second in 2003-04, Sutton led the Golden Eagles to the first of four conference championships. ORU won at least 21 games per year from 2005 to 2008, including a 25-win campaign in 2005.

Sutton’s teams left a wake of big wins over notable programs, including victories over the likes of Arkansas, Georgetown, Missouri, Nebraska, Stanford, and even Oklahoma State and Kansas.

A 78-71 win in Allen Fieldhouse against the No. 3 Jayhawks on Nov. 15, 2006 put the basketball world on notice – ORU had arrived. The Golden Eagles would go on to win 21 games that year, capture the Summit League regular season and tournament crowns and advance to the NCAA Tournament.

They would return to the Big Dance the following two seasons, which marked the first back-to-back trips to the NCAA Tournament in school history.

Sutton and the Golden Eagles would return to postseason play in 2011 (CIT), 2012 (NIT) and 2013 (CIT), as well as 2015 (CBI).

Known for his player development, Sutton coached Caleb Green to three All-America seasons and Summit League Player of the Year awards and helped Dominique Morrison earn All-America honors and Summit League Player of the Year in 2012. He also coached five Freshman All-Americans, four conference Newcomers of the Year, two league Defensive Players of the Year and three Sixth Men of the Year.

Those accolades would lead to plenty of recognition for Sutton as well. He was named the Summit League Coach of the Year in 2002, 2008 and 2012, the NABC District 12 Co-Coach of the Year in 2005 (shared the award with his father, Eddie Sutton) and was the Clair Bee National Coach of the Year finalist in 2007.

Sutton is the all-time leader in Summit League conference victories with 173, and his 66.5 win percentage in Summit League games rank third all time.

Sutton and his wife, Kim, are the parents of three daughters: Hallie, Lauren and Maggie.


Assistant Coach | David Kontaxis

Coaching veteran David Kontaxis joined the Cowboy basketball coaching staff as an assistant in May of 2017.

Kontaxis spent the 2016-17 season as an assistant coach at James Madison University, and has a history of success in the Amateur Athletic Union (AAU) organizations in the Mid-Atlantic region.

“David is a guy that I’ve gotten to know really well throughout this process, and he is a perfect fit for the Oklahoma State basketball program,” Boynton said. “He has great recruiting ties in the East, which is an area we plan on recruiting heavily over the coming years, and he’s known as a fantastic communicator with young men. David has coached at just about every level in this game, and I really look forward to him joining the Cowboy basketball family.”

In his one season at JMU, Kontaxis helped seniors Dimitrije Cabarkapa and Paulius Satkus become the first Dukes duo to earn Colonial Athletic Association All-Academic Team honors since 2008.

Prior to JMU, he spent the previous seven years coaching successful AAU squads. He worked in the Washington, D.C. area with DC Assault before more recently working with Team Loaded in the Virginia/North Carolina area. Kontaxis worked primarily with the U17-U15 teams as the lead recruiter.
Prior to entering the AAU realm, Kontaxis acted as the director of basketball operations at William & Mary for the 2008-09 season.

“I’m excited to be a part of the Oklahoma State program, which has so much tradition and a history of success,” Kontaxis said. “I have a tremendous passion for the game of basketball, and I’m looking forward to working with coach Boynton in keeping the success rolling in Stillwater.”

He got his start in coaching at the prep level, serving for seven years at Central High School in Capital Heights, Maryland. From 2001-2006, Kontaxis was the assistant coach before earning a promotion to head coach for the 2006-07 and 2007-08 seasons.

Kontaxis played basketball collegiately at Montgomery College-Germantown from 1995-97. He served as a team captain during his final season in 1997. Kontaxis earned his associate’s degree from Montgomery College-Germantown in 1997 and was a Dean’s List student.

He went on to earn his bachelor’s degree in social science education from South Florida in 2000. In 2004, Kontaxis received his master’s in education from John Hopkins University in Mild to Moderate Disabilities.


Assistant AD/Basketball | Lance Troester

Oklahoma State basketball coach Mike Boynton has appointed longtime OSU administrator Lance Troester as the program's assistant athletic director for men's basketball.

Troester arrived in Stillwater in 2006, and has worked closely with the basketball program as OSU's assistant AD/compliance. No stranger to his new role, Troester previously served as the assistant director of men's basketball operations at Florida State under former Cowboy head coach Leonard Hamilton.

"Lance brings tremendous value to our staff as our new assistant AD for basketball, and we're excited to have him come on board with us," Boynton said. "He'll obviously be involved in the day-to-day operations of our program, but he'll also be heavily involved with our on-campus activities from a recruiting standpoint. Most importantly, he'll be someone who keeps the staff organized internally. He has great experience in this role from his time at Florida State, and he's someone that brings a great deal of compliance knowledge as well. I look forward to working with him going forward."

Since arriving at OSU, Troester has worked with every Cowboy and Cowgirl sport in helping oversee the compliance department in its mission of developing, implementing and maintaining effective policies and procedures related to compliance with the NCAA, Big 12 Conference and the institution itself.

In his new position of assistant AD/basketball, Troester will handle the day-to-day operations of the program, including team travel and scheduling.

"I would like to thank coach Boynton for this wonderful opportunity to join his staff," Troester said. "I've had the opportunity to get to know him over the last year, and I'm very excited about the direction of OSU basketball. I've been fortunate enough to work closely with the men's basketball program over my 11 years at OSU, and I'm excited about joining such a historic program in a role I have such passion for."

A native of Garnavillo, Iowa, Troester earned his Bachelor's degree in Exercise and Sports Science/Sports Management from Iowa State University in 2002. While at Iowa State, he worked with the Iowa Community College Athletic Conference (ICCAC) and volunteered with the Iowa State Games.

After earning his undergraduate degree, Troester accepted a position at Florida State University as the assistant director of men's basketball operations, where he coordinated team travel, organized recruiting visits, and assisted in organizing the Leonard Hamilton Basketball Camps as well as the community relations events for FSU players and coaches.

Troester went on to earn his Master's degree in Sports Management from Florida State in 2005, and served as a graduate assistant in the compliance office at Florida State athletics.

He and his wife, Jamie, have a daughter, Lilli.

Director of Player Development | Keiton Page

Oklahoma State head coach Mike Boynton has named Cowboy basketball great Keiton Page the program’s director of player development.

Page arrived at OSU in 2008 as one of the most heralded players in Oklahoma high school basketball history, and went on to score 1,651 career points for the Cowboys, which ranks 10th in school history.

He was a two-time All-Big 12 Conference selection, and his 299 career 3-pointers were the standard until Phil Forte III broke Page’s record in January of 2017. Page ranks eighth among all OSU players with 108 career starts, and his career free throw percentage of 85.9 ranks fourth.

“Being around Keiton, it doesn’t take you very long to realize that he’s a Cowboy,” Boynton said. “He has a tremendous passion for this University and this program. He’s served in every role imaginable for this program over the last 10 years, and he’s someone that we would have really missed had we not been able to keep around. He’s an unbelievable asset, and no one can better tell the story of what it’s like to be a Cowboy than Keiton Page. I really look forward to working with him in this new role.”  

For the last five seasons, Page has served in various roles on OSU’s coaching staffs, and helped the Cowboys reach the NCAA Tournament in four of those campaigns. Page was the assistant director of strength and conditioning under Travis Ford, and was named Brad Underwood’s assistant director of player development for the 2016-17 season.

In his new role on Boynton’s staff, Page is expected to play a large role in OSU’s recruiting efforts, as well as video scouting, game preparations and individual skill development. As a recent graduate, Page is also expected to be a mentor to young players on the OSU roster.

“I’m extremely excited to work with coach Mike,” Page said. “What stands out most about him is how much of a people-person he is, and how much he shows the players that he genuinely cares as much about them off the court as on it. I was recently in all of these players’ shoes, and I can relate to just about everything they’re going through – the lows and the highs. So, I’m excited to join coach Mike in helping the next generation of Cowboys grow and develop into standouts on the court, in the classroom and in the world.”

Strength & Conditioning Coach | Jake Manzelmann

Jake Manzelmann is in his 11th season as the speed, strength and conditioning coach for the Cowboy Basketball program. This is his second stint at Oklahoma State as he worked as a graduate assistant during the 2004-05 season working primarily with the football and women's basketball programs.

Manzelmann has transformed several Cowboys through conditioning and strength training. Byron Eaton, who weighed in at 248 pounds upon his arrival in Stillwater, went on a strict diet and workout regimen under Manzelmann's supervision. By the time the season began, Eaton was competing at his ideal playing weight of 205 pounds throughout his senior season.

Conversely, Manzelmann can also transform players in the opposite direction. Marshall Moses arrived at OSU weighing 213 pounds, but after three years, began his senior year at 255 and became a dominant big man in the Big 12. In just three short months after his arrival in Stillwater as a freshman, Le'Bryan Nash put on 15 pounds of muscle and was quickly ready to battle at the collegiate level.

Another instance is the transformation of Michael Cobbins. When the OSU post player arrived from Amarillo, Texas, his measurements were 6 feet, 8 inches tall and 183 pounds. With a redshirt season and Manzelmann's strength program, Cobbins enters his senior year at 230 pounds and a clearly more muscular frame.

During the one-year hiatus from Stillwater, Manzelmann spent a season as an assistant strength and conditioning coach for the football program at Texas Tech. He also served as the strength and conditioning coach for the local minor league hockey team.

Manzelmann initially came to Oklahoma State from Northeastern University in Boston, Mass., where he worked specifically with the football, women's basketball, and men's & women's hockey teams.

A graduate of Northeastern Oklahoma State University in Tahlequah, Manzelmann is strength & conditioning coach certified (SCCC) and is also certified as a corrective exercise specialist (CES).

Manzelmann and his wife, the former Taylor Hardeman, were married on May 18, 2012. Taylor played basketball for the Cowgirls from 2005-09. The couple has two children.


Video Coordinator | Dre Denbow

After serving the 2016-17 season as a graduate assistant, Dre Denbow was promoted to video coordinator of the Cowboy basketball program by head coach Mike Boynton.

Denbow will serve an instrumental role in scouting upcoming opponents, as well as cutting and evaluating practice and game footage to help each player improve their performances.

As a graduate assistant, Denbow played a similar role in helping the Cowboys reach their full potential. With Denbow’s assistance, OSU point guard Jawun Evans became the 22nd All-American in program history, and Jeffrey Carroll grew from a spot shooter into an All-Big 12 wing.

A native of Pembroke Pines, Florida, Denbow earned his undergrad from Florida Gulf Coast in 2014, where he served as a student manager for the basketball program. In fact, Denbow was a part of the Eagle’s magical run to the Sweet 16 in 2013.
