Warrenfeltz steps down after posting a 46-40 record in four seasons, including a 9-16 record last season with a North team comprised largely of underclassmen.
"I'm real proud of the position that the program is in," Warrenfeltz said. "If it were a situation of quitting after a bad season, I would have done it at the end of the season. We were playing a lot of young kids. I really feel like the program will be in good shape for the next couple of years."
Warrenfeltz's best season was 1994 when he led the Hubs to a 17-6 record and an appearance in the Class 2A state semifinals. He was named the Herald-Mail's co-coach of the year.
"When you first take a job, you figure you're going to be there for 30 years and you make all these goals," Warrenfeltz said. "I waited and waited to make this decision and I tried to talk myself back into it, but every time I tried, I kept seeing my kids."
No one has been appointed to replace Warrenfeltz, but he said he doesn't think it will take too long.
"Year in and year out, North Hagerstown has been a strong job," he said. "We have always been there and been competitive."
And the time may come when Warrenfeltz will want to be competitive again.
"Ten years from now, I can get back into coaching if I figure I need it again" he said. "But I can't make my kids 6 and 10 again."
