Sallie Bartkowiak Assistant Coach


Hello!  My name is Coach Sallie. 

I have been a USA Swimming certified Coach since 2015, and nothing gets me more excited than seeing swimmers improve and reach their goals and fall in love with the sport I am so passionate about!


As an Assistant Coach with Sailfish Swim Club since 2019, my main coaching focus is our younger age group swimmers  5-12.   The focus at these ages is developing core strength, a good aerobic base, proper kicking and of course good technique habits in all 4 strokes.  Training is only one part of being a successful swimmer; our Sailfish athletes must also be good teammates and commit to a Safe Sport environment.


I  grew up in Plymouth, MI where I learned to swim at the age of 5 and continued  swimming competitively until my freshman year at MSU.  An illness derailed my swimming career for decades, and I did not return to the sport until 2015, joining Michigan Masters Swimming and becoming a Level 1 & 2 Masters certified Coach.
