Dan Torralva Assistant Coach

Hello! My name's Dan Torralva and 2020's my first year coaching in the BC community. I started coaching swim lessons as well as a recreational swim team in 2013 and absolutely fell in love with it! By 2017 I was a USA certified coach. Well before that, I started swimming competitively at 7 years old and swam through high school. I consider myself lucky to be a part of this team and coach a sport I've enjoyed so much. I believe in kids swimming smart, working hard, and having fun! 

This past summer in 2020 I married my best friend Tricia, and together we have two (not so little anymore) swimmers, Saydee and Ellie. We've got two more future BC swimmers on the way. We look forward to many fun-filled seasons to come!
