Enrichment Programs

In addition to our school programs, we offer many different enrichment programs for your child. Enrichment programs include a school-wide music class with Music ‘N Me, the Morris County Library Monthly Book Loan Program, and various “in house” special events and visitors.

MLCDS also hosts several outside programs that families can add to their child’s schedule for additional enrichment opportunities. They are:

  • Technology Toolbox – www.TechnologytoolboxNJ.com
  • Music & Me – on Facebook – Miss Paula’s Music & Me
  • 123 Tumblebus – www.123tumblebus.com

“Our son started at Mountain Lakes Country Day School when he was five months old. When he was six months old, I experienced a major health crisis. When he was 17 months old, he was diagnosed with Sensory Processing Disorder (SPD). Through it all, the MLCDS staff have been incredibly supportive of our family as a whole. My son has stayed at MLCDS through Kindergarten, instead of going to our township school, because we have felt that strongly about the excellent care and education he is getting at MLCDS. I would highly recommend any parent seriously think about sending their child there, even children with mild special needs, because the staff is that good with the kids. My son would not be as successful academically and socially as he is today if not for the care he’s received at MLCDS.”
