SAFETY. At ISR, safety will always come before convenience. While it is a fair amount of paperwork, any program that involves the safety and well being of infants and young children needs to be conscientious and very thorough. The ISR medical team, consisting of an on-staff team of registered nurses, review the information from the registration form and provide feedback to your child’s Instructor so that he/she can provide the safest possible lessons for your child.
