Mia Miller

White Group Coach


I began competitively swimming when I was 6 and continued on with my swimming career through college, where I swam for Ball State University. I soon began coaching after that and fell in love. I have experience coaching every age group, from Toddlers to High School State Finalists and Olympic Trial Qualifiers. My favorite part of coaching is going through the journey with each and every swimmer—the successes, failures, tears, and laughter—it is what makes us family and builds us up as individuals and as a team.


Favorite phrase at practice: I’m not telling you to do it, I’m asking you to try.

Lisa Kim

Developmental A Coach


My favorite moment is when  a swimmer accomplishes something they have worked hard on and you can just see when it “clicks” or their goal is achieved. That smile on the swimmers face is priceless. I believe the most important thing in swimming is to have fun! 

"Practice how you want to see yourself competing."

Assistant Developmental B Coach


As a recent IU grad, I'm excited to be coaching for GSI.  I was a swimmer from Elementary to High School.  It's the best stress reliever I've found.
