Miller, 37, resigned as the Lightning's athletic director in July after a six-year run. He's not going anywhere — he said he resigned so he could spend more time concentrating on teaching math and coaching cross country and track and field at the school.
But in the time the Irvine resident was athletic director at the school on the hill in Newport Coast, he turned CIF from unknown to a reality.
Year after year, for almost every sport.
Boys' and girls' volleyball coach Dan Thomassen arrived at Sage Hill in 2003. Two years later, his girls' volleyball team won the CIF Southern Section Division IV-A title, one of two CIF titles Sage Hill won during Miller's tenure. The other was won by girls' tennis, a Division V crown, just two days later.
"He really cares about everything," said Thomassen, who teaches science at the school. "He has been as important to the success as any of the individual coaches, if not more so. He had things very well in order. He's a math guy, so he makes sure things add up. But, the main thing is he cares."
Miller wasn't at Thomassen's CIF title match in 2005. But he said he had a good reason — he was coaching at the CIF cross country finals instead.
"I was somewhat surprised that we had success as quickly as we did," Miller said. "Pretty remarkable. I think that had a lot to do with the coaches that we had and the kids that we had, just working really hard. Tennis had three years where it made the [CIF] semifinals before getting to the championship. [The players] saw what it took, I guess, to get to that championship level."
