Coaching Staff

With more than 250 years of combined experience, our coaching staff at COSA Swimming is truly best in class. Our coaches have worked with swimmers to achieve Olympic Trials cuts, become NCAA super stars, break age-group records, etc., and our coaches have their own accolades too, including numerous "Coach of the Year" recipients.
