Coaching at Flagler
Greg Guilliams begins his second year at the helm of the Flagler baseball program. In his 35-year career, Guilliams has compiled a 1,208-600-2 record, which calculates to a .668 winning percentage. His win total ranks second among active coaches in NCAA Division II, seventh all-time, and his winning percentage is in the top 15 among active coaches. Guilliams spent 17 years at Valdosta State University and prior to that had a 16-year run at Embry-Riddle Aeronautical University in Daytona Beach, Florida. Throughout his career, three words have been the driving force of his teams and his philosophy – energy, discipline, and resolve.
He guided the Saints to a 30-20 overall record and a 13-14 mark in the Peach Belt Conference in his first season. Guilliams led the Saints to a PBC Tournament appearance and had three players earn first team all-conference honors and another to D2CCA All-Southeast Region accolades. Four players earned academic all-conference recognition. The Saints led the PBC in earned run average (3.74) and stolen bases (128).
Prior to Flagler
He started at Valdosta State in 2008. He guided the Blazers to two of its four Gulf South Conference titles (2010 and 2013) as well as a GSC East Division title in his first season. The Blazers made back-to-back NCAA Tournament appearances in 2022 and 2023 as well as 2009 and 2010.
A Valdosta State player earned All-America honors nine times under Guilliams. The 2009 and 2010 NCAA Division II South Region and 2009, 2010, and 2012 GSC Player of the Year all wore the red and black. Forty-eight players have earned all-conference honors in the last decade and multiple players were selected in Major League Baseball’s First-Year Player Draft. Guilliams was selected as the GSC Coach of the Year in 2010.
Prior to Valdosta State, Guilliams built a fledgling Embry-Riddle program into a dominant force in the NAIA. In 16 years at the helm, he produced a 663-236-1 record, an average of 41 wins per season. He was the Florida Sun Conference/NAIA Region XIV Coach of the Year seven times and was the American Baseball Coaches Association’s NAIA Regional Coach of the Year six times. Guilliams coached the Eagles to 11 NAIA Tournament appearances, six NAIA World Series appearances, and took the team to the finals in 2005. Forty-four players received All-American accolades and he coached the 1996 NAIA Player of the Year, Frankie Thompson.
Guilliams played collegiately at Ohio Dominican University in Columbus, Ohio and garnered NAIA All-America honors three times. He was part of the inaugural class of the school’s athletics hall of fame in 1997.
After graduation, he played professionally in the Atlanta Braves organization and moved onto Eastern Kentucky University in Richmond where he served as a graduate assistant in 1987 and earned his master's degree.
