Monterio admits she had a case of nerves at the state meet last year, and said that experience should help her this year.
"Last year, I was so nervous that I didn't really swim that well," Monterio said. "This year, I know what it's going to be like and I've swam at UK a lot since then, so it won't be as much pressure (if she gets to the state meet)."
Monterio hasn't shown much aversion to pressure. Despite being only in middle school, she has already broken three Boyle school records: the 200 individual medley, the 100 butterfly and the 100 backstroke.
One of those records used to belong to Estes.
"I expect her to break the school records she already has, and to continue to do that," Estes said. "For her to have done what she's already done at such a young age is wonderful for her, and I expect her to only get better."
"I didn't think I'd break three within my first two years," Monterio said.
Monterio is definitely confident, and her swimming shows that. Her ability to focus on the task at hand helps her, according to Estes.
"She's very goal-oriented and she knows what she has to do to accomplish them," the Boyle coach said.
Monterio's future goals might seem strange to some. Rather than finding one or two events she excels at and sticking with them, Monterio said she has every intention of being successful in all of them.
"I want to, at least, win the region every year and make it to state," Monterio said. "Maybe I'll do different events every year just to do something different and still make it to state."
Her early success has led to support from some teammates and scorn from others. But Monterio said she appreciates those that appreciate her.
"Some of them are really supportive and really helpful," Monterio said. "Bruna (Lozano) is always congratulating me and stuff, but then others are just like 'Well, she gets really lucky,' and stuff like that. But most of them are really appreciative and excited."
