Instructors
Who Are We?
We are NOT people who need to make a living off separating you from your hard earned money.
We are volunteer instructors and retired competitors giving back to our sport and our community. Any proceeds received from dues paid to the Parks and Rec. Department are reinvested in our club and our students.
Our dues are purposefully low and sholarships are available.
