Randy Clark, who led Porter-Gaud to three SCISA state basketball championships and coached for nearly three decades, died Monday after a brief illness. He was 63.

Clark was the dean of area basketball coaches when he resigned as Porter-Gaud coach in May 2006.

Clark was a head coach for 28 years, including 26 at Porter-Gaud. He built the Cyclones into a perennial state power and posted a 435-210 record at the West Ashley school. He led the Porter-Gaud boys team to three straight SCISA championships (2003-05) and two state runner-up finishes. Clark, who spent two years at Bishop England, owned a 453-232 career record.

Clark continued to serve as the middle school principal at Porter-Gaud.

“I don’t think I’ve met a finer person,” Porter-Gaud athletic director Ed Steers said. “He had a big heart and reached out to everyone. He’s brought many happy moments to many peoples’ lives.”

Clark got his first head coaching job at Bishop England and spent two seasons at the school. Bishop England athletic director Paul Runey was stunned when he heard the news of Clark’s death.

“He and I were good friends over the years,” Runey said. “I had the opportunity to coach with him and socialize with him. He was just a good guy.”

Clark was hired at Porter-Gaud in 1976 by the school’s first headmaster, Berkeley Grimball, after his brief stint at Bishop England.

His 26 seasons as coach at Porter-Gaud were briefly interrupted by a few seasons as an assistant coach at the College of Charleston, where he worked under his former coach, John Kresse.

He also coached Kresse’s sons, John and Ryan, and they were on the teams that won state championships.

“Randy Clark will be very much missed by the College of Charleston, the Charleston community and myself,” Kresse said. “Randy Clark played basketball at the College of Charleston and was a faithful assistant for me during the NAIA days.”

Clark was honored as region coach of the year six times and SCISA state coach of the year five times. He was inducted into the Porter-Gaud/Porter Military Academy Athletic Hall of Fame in 2010.

Clark served as Porter-Gaud’s middle school principal for 21 years and for five years also served as athletic director.
