Favorite coaching quote: “Good or bad, Practice makes permanent”

Calvin started his swimming career as a member of the MACR Sharks before moving on to club swimming and then eventually to college swimming.  As a member of the University of Minnesota team, Calvin excelled in backstroke events.  He also holds the 200 IM record for Linn Mar High School making Calvin a great all-rounder.  Calvin has been on the coaching staff of LMST for 1.5 years and is excited to be coaching with MACR.  Calvin hopes that swimmers will learn that swimming is about more than just technique and racing, that it’s about finding new ways to improve both in and out of the pool, mentally and physically.  Fun Fact about Calvin – he is completely deaf in his right ear.  Make sure you approach from the right (unless you want to sneak up on him!)
