Dennis Moore is leaving his position as track consultant at Santa Anita on Dec. 31, he said on Friday.
Moore said that the decision has been planned for months.
“I gave them my notice in September,” he said. “I just turned 69, and when you get to that that age you start winding down.
“It was a hard decision. They’ve been good to me and I’ve enjoyed it. I’m proud of what we accomplished over there.”
Moore said he will be replaced by Andy LaRocco.
