Katie's Favorite Events: 200 IM and 100 Free.

Katie's favorite thing about coaching is celebrating successes with swimmers! "I love to see swimmers beam with pride in their accomplishments, especially when their experience on the team has helped them understand and appreciate all the variables involved in their success. I love it when kids start to see the connection between listening, learning, working and succeeding. To me, this is the primary goal of any youth program, and I love being part of this process!" Katie's goal for this year is to add a lip sync/dance contest to the end of the season banquet so the Intro group can show the other groups HOW IT IS DONE!

Katie's favorite Riptide experience is playing "pool Tenzi" with her Intro group over Christmas break each year.
