Walter Hardy, who had been a coach, teacher and athletic administrator for Montgomery County Public Schools for more than 25 years, died early Saturday. The cause of death was still unknown to friends and colleagues reached Sunday morning, but those close to him called it "tragic" and "out of nowhere." Hardy, who was 50 years old, is survived by his wife, Mary, and their children, Olivia and Chase. He was hired in May to be Sherwood's athletic director and started in that role on July 1. Before taking the job at Sherwood, he was the athletic director at Kennedy for two years and, before that, Paint Branch's head boys basketball coach for 17 seasons. He was named All-Met Coach of the Year in 2000 after leading Paint Branch to Maryland's 3A state basketball title. Memorial arrangements for Hardy are still pending, Sherwood principal Bill Gregory said Sunday. Sherwood football coach Chris Grier said Sunday that "things are in the works" to honor Hardy in the near future. "He came in every single day in my office or out on the field, always happy, always joking around," Grier said. "He was just a joy to be around, honestly, just a breath of fresh air. I'm going to miss him, we were really looking forward to a number of years with him. It's a shame, and it hurts a lot." Gregory said that he got a call around 12:30 p.m. on Saturday saying that Hardy had died. "I don't think a lot of us have even had a chance to process this," said Paint Branch basketball coach Chris Bohlen, who took over for Hardy when he took the job at Kennedy. "A lot of us coaches were talking (Saturday), Walter was always running around, always going to a game. He was always full of energy and it wasn't like he was battling health issues. It was just so sudden that I think that made it worse."
