Our experienced staff knows how to nurture each unique child. All of our teachers are certified by state standards and trained in early childhood growth and development. Through participation in continuing education workshops and seminars, our teachers are always learning and bringing fresh ideas to their work.

All are trained in pediatric CPR and First Aid. In addition, they are experienced parents, bringing to their jobs extra sensitivity to the joys and occasional frustrations of the preschooler.

Special Staff

In addition to our regular classroom Teachers, NNS has a “float” teacher.  This person circulates among the classrooms helping with special projects, toileting needs, clean-up, snacks, dressing for outdoors and generally maintaining our adult/child ratios at all times.

Music is presented to our children once per week using the talents of teachers specializing in those areas.
