Nina Grino joined the Troubadour swim program for the 2023 season.

She is no stranger to the area swim community, having competed for DART Swimming Sacramento from 2010 until her graduation from Rio Americano High School in 2021. While pursuing her degree in mechanical engineering, she served the 2022 season as the head coach at Grant Union High, guiding many athletes from relatively novice levels of swim experience to competing in the finals of the Metro League Championships. Grino returned to her old DART stomping grounds in 2022, this time as a head coach for the Summerdarts program.
