My curriculum is not swimming, it's the swimmer. Ultimately, you swim to learn about yourself--nothing matters more than knowing who you are.
Patricia Sullivan Orange Group Lead Coach

Patty Sulivan has over 25 years of coaching experience at both the USS and high school level.  She swam collegiately at Santa Rosa Junior College, and earned All American honors for two seasons before also swimming at Chico State.  Patty's goals are to focus on giving the Orange Group the basics of each stroke, and building each swimmers confidence.  With these tools she hopes they will all carry with them a love of swimming well into adulthood.
