Coaching Staff


Dino Presley and Marlon Guild are the newest members of the Bronc coaching staff. They replace Donyell Marshall, who has taken a similar position at the University at Buffalo, and John Griffin, who went back to his alma mater, Bucknell, to serve as an assistant coach.

Presley has been an NCAA Division I assistant coach since 1997. “I am excited to have Dino on board with us here at Rider,” said Baggett, the 2015 MAAC Coach of the Year. “Dino brings a wealth of knowledge and recruiting experience from the different programs he's been with.”

Presley comes to Rider from the New Jersey Institute of Technology, where he helped NJIT compile a program-record 21 wins and advance to the semifinals of the College Insider.com Tournament.

Prior to NJIT, Presley has worked at Marshall, Saint Bonaventure, UMBC, East Carolina, Towson and Drexel.

“Dino and I worked together some years back at UMBC and I thought he did a great job,” Baggett said.

Presley has made a name for himself as a notable recruiter and player-developer.

Presley is a graduate of Kutztown University.

Guild comes to Rider from Saint Peter’s University, where he spent seven seasons as the men’s basketball recruiting coordinator.

Geoff Arnold Assistant Coach

Rider Men’s Basketball Head Coach Kevin Baggett announced the hiring of his former Saint Joseph’s teammate, Geoff Arnold, as an assistant coach prior to the 2019-20 season. Arnold brings decades of experience, most recently at his alma mater. In addition to two stints with the Hawks, Arnold has gained college experience at Drexel and Massachusetts.

In his most recent stint, Arnold spent 11 years on Phil Martelli’s staff at Saint Joseph’s. A former Hawk standout, he also served as an assistant at Saint Joseph’s for four years from 1993 to 1996, giving him a total of 15 years on the Hawks’ bench. That stint included one year with Martelli, who was in his first season (1995-96) as head coach, where the Hawks went 26-6 and reached the NIT Championship game. Arnold was also a volunteer assistant coach on Jim Boyle’s staff in 1988-89.

A 1986 SJU graduate, Arnold was part of three of the Hawks’ four Atlantic 10 Championships, as a player in 1986 and as an assistant coach in 2014 and 2016.

Prior to making his return to Saint Joseph’s, Arnold was the associate head coach at Drexel University for seven years. While there, he was instrumental in the Dragons’ recruiting efforts that helped them reach the postseason four times in seven seasons, including a 23-9 record in 2006-07.

Arnold left Saint Joseph’s in 1997 to join former Hawk teammate Bruiser Flint at the University of Massachusetts, serving on Flint’s staff for five years. He then returned to Philadelphia in 2001 when Flint was named head coach at Drexel.

Arnold, who was a senior tri-captain for the 1985-86 Saint Joseph’s team that won the Atlantic 10 Championship, recorded 26 wins and earned a bid to the NCAA Tournament. During his senior season, which was Martelli’s first as an assistant coach at SJU, the guard averaged 8.9 points and led the team with 134 assists. He was inducted into the Saint Joseph’s Basketball Hall of Fame in 1992.

Originally from Sharon Hill, Pa. and Darby Township High School, Arnold is the uncle of former Saint Joseph’s star Langston Galloway, who is currently with the NBA’s Detroit Pistons. In 2018, Arnold was inducted into the Pennsylvania Sports Hall of Fame – Delaware County Chapter.

Arnold and his wife, Dr. Stephanie Tryce, reside in Philadelphia. They have a daughter, Gabrielle.

Roy Blumenthal Director of Player Development

Roy Blumenthal was named Director of Player Development prior to the 2019-20 season. Blumenthal came to Rider following his 14th season as the top assistant coach for the West Chester University’s Men’s Basketball program, his 25th overall. Coach Blumenthal had also been the Head Coach of GSA’s Goodwill Select Teams. His strong and extensive coaching expertise and experience is notable and his dedication to generating high caliber international competition for athletes and coaches is unmatched. Furthermore, he possesses great energy, enthusiasm, and motivation, which he utilizes to mentor youth and colleagues admirably.

Such passion and commitment led to Coach Blumenthal’s receiving West Chester University’s Men’s Hall of Fame Milt Blitz Award in 2007 for his outstanding contribution to the game of basketball as a University alumnus. Blumenthal earned his Bachelor of Science degree in Sports Management in 1983 from West Chester University.

Kim Waiters - Assistant Coach

Kim Waiters joined Kevin Baggett’s staff in July 2021. Waiters joined the Broncs following six seasons at NJIT.

In six seasons as an assistant coach at NJIT, Waiters helped lead the Highlanders to 83 victories, six All-Conference selections and three Conference All-Rookie Team honorees.

Waiters helped make NJIT history in the 2018-19 season with a 22-13 record, 11 road wins and 13 non-conference wins – all program records. NJIT’s ASUN Championship Quarterfinals win at Florida Gulf Coast marked the program’s first-ever ASUN tournament victory. The team earned its third CIT berth and advanced as far as the CIT quarterfinals following a first round win as second round bye as one of the top three seeds in the tournament. The 2018-19 season was the winningest in program history.

For the first time in program history, NJIT received its first AP Top-25 Poll vote on Dec. 10, 2018. The Highlanders received one vote for three consecutive weeks (Dec. 10-24).

The 2018-19 team earned multiple accolades for their performances on and off the court, including Abdul Lewis (Preseason All-ASUN, First Team All-ASUN), Zach Cooks (Second Team All-ASUN), Shyquan Gibbs (ASUN All-Academic Team, CoSIDA Academic All-District), Diandre Wilson (ASUN All-Tournament Team) and Reilly Walsh (Preseason Fan-Voted ASUN Defensive Player of the Year).

Individually, Lewis broke Tim Coleman’s all-time rebounds record (773), eclipsed 1,000 career points (1,015, NJIT & 232 South Alabama), reached 1,000 career rebounds (773, NJIT & 227, South Alabama), broke his own single-game rebounds record versus Jacksonville with 21 boards and set NJIT’s double-double record with 22 in his three seasons for the Highlanders. Cooks also added his name to the record books by tying Damon Lynn’s single-game scoring record (34 points) against Quinnipiac in the CIT First Round and averaged 17.6 ppg, third most in NJIT history.

Waiters also coached Damon Lynn for two seasons, who became the program's all-time leading scorer on Nov. 11, 2016, and finished his career with 2,153 points. He currently ranks fifth in Division-I history with 434 career three-pointers.

He also coached Tim Coleman for two seasons with NJIT as he finished as the program's all-time leading rebounder (762) and fourth all-time scorer (1,462). He departed the NCAA ranks as the only active Division-I player with at least 1,400 points, 750 rebounds, 225 assists (244), 150 steals (154) and 135 blocks (135).

In Waiters’ first year as an assistant in the 2015-16 season the Highlanders finished 20-15, earning its second consecutive CollegeInsider.com Postseason Tournament (CIT) berth, advancing as far as the semifinals. In addition, NJIT scored their first-ever win over a BIG EAST Conference opponent when they topped St. John’s in December 2015.

Waiters got involved with coaching when he was an undergraduate at Robert Morris in Pennsylvania.

At Robert Morris, Waiters worked as a student assistant and, after graduating in 2011 with a bachelor's of Business Management, Waiters became the Director of Skills Camps at the Pocono Invitational, a prestigious overnight camp that began operation in 1963.

From the Pocono Invitational, Waiters headed to The Hoop Group, the largest basketball instruction organization in the world. Waiters directed 10 Premier Grassroots AAU team tournaments and 16 high school events featuring premier teams from Pennsylvania, New Jersey, New York and Maryland.
