Bronsen Trunzo had an incredible swim season. As a five-year-old competing against six-year-olds, Trunzo went undefeated in dual-meets. He also won the high point at Bottom's Up Invitational and at Meadow Mini Meet Invitational, where he broke a 20-year-old meet record in the 25 back.
Following his top finish at OMPA, he competed at the Contra Costa County Championships where he placed third in back and third in breast.
