Why Cornerstone

Time to discover, pretend, dawdle and play.

Self-esteem flows from success working at the business of living. Our teachers are there to explain, encourage, facilitate and comfort as children pursue what interests them.

  • Frequent, positive, warm interactions between adults and children
  • Planned activities appropriate to each child’s age and development
  • Specially trained staff who respond to individual children
  • Varied, age-appropriate toys and equipment
  • A healthy, safe environment — with a canopied play space for rainy days
  • Planned, nutritious meals and snacks
Our approach
What families get

Peace of mind, built in.

Real food, made here

Lunch and two snacks a day from our Class 4 commercial kitchen, reviewed by a dietician consultant. We strive to be peanut/nut free.

Daily communication

Daily notes and infant logs, conferences, a monthly newsletter and calendars — you always know how your child’s day went.

Safe, open environment

Keypad entry, positive ID at pickup, large open rooms with lots of windows, and staff trained annually in safety and first aid.

Learning that sticks

The Creative Curriculum paired with CT Early Learning & Development Standards, with regular developmental assessments.

Long-tenured educators

We take pride in staff longevity. Our team regularly exceeds the state’s required hours of continuing education.

Nothing to pack but love

Formula, baby food, crib linens, cot sheets and bibs are provided — so mornings are a little easier.

Owner-operated since 1996

Two educators. One shared mission.

Lisbeth Olsen Condo and Christian Mirowski — friends for more than 30 years — lead Cornerstone together, bringing decades of classroom experience and a deep commitment to children, families and staff.

Come visit us

Look for our white, single-story Cape Cod–style building just west of the Merritt Parkway between exits 29 & 30 — with ample parking, enormous fenced playgrounds, a canopied play space for snowy New England days, and solar panels on the roof.
