Every coach is USA Swimming certified.  That is the lowest, base level of certification.  Being ASCA Certified means that our club commits to annual professional development training, just like any other profession.  In addition, ASCA Certification (five levels) means that our coaches commit to a Professional Code of Ethics that has been in place much longer than the USA Swimming Code.  Each Level that you see reflected on our website  reflects both academic training specific to swimming and the in-pool success of that coach’s swimmers and the coaches’ level of experience.   Our club requires all of our coaches to commit to that Code of Ethics and to annual professional development, and our club supports them in doing so.
