Hands-on, involved & passionate in the care of your children

Founded in June 2004 by owners Ashleigh and Ryan Zimmerman, Aa to Zz is a family-run business led by people who are hands-on, involved and passionate. The first child care center in Harrisburg opened its doors with just two children enrolled - one being the Zimmerman’s oldest son.
The center expanded in the next few years to five centers and continued to grow. “Our initial success was thanks greatly in part to the endless amount of energy we poured into our first center,” says owner and co-founder, Ashleigh Zimmerman.

Making the World a Better Place, One Child at a Time
As a busy caregiver, you depend on your child care center to nurture your child in a safe, fun and enriching environment. At Aa to Zz Child Care and Learning Center, our mission is to help your child thrive through loving care and developmentally appropriate activities that stimulate cognitive, social and emotional growth. Our Harrisburg and York area child care centers offer reliable full-time, part-time, drop-in, summer camp and before-and-after-school care for families in the central Pennsylvania region. When you choose Aa to Zz Child Care and Learning Center, together we’ll make the world a better place, one child at a time.
Aa to Zz Child Care and Learning Center offers the loving, caring and nurturing experience your family deserves. We believe keeping children safe in a fun and rewarding environment leads to natural opportunities to learn — whether cognitively, physically or socially. Your child will flourish in our hands-on, play-based environment, where outdoor play and building, climbing, exploring and discovering are on the agenda every day. We believe so strongly in our screen-free, nature-based curriculum that we ignored classroom-ready programs and developed our own instead!

Aa to Zz operates eight child centers across Dauphin, Lebanon, & York Counties. Aa to Zz’s facilities are unlike any other in the region. Whether you’re considering our child care center in Hummelstown or our Palmyra preschool program, you’ll find classrooms stocked with toys made from natural materials such as wood, felt and silk.
We have three day care centers in Harrisburg. You can find our Harrisburg child care and preschool programs in Hanover Township, Swatara Township & off of Route 39.
You won’t find televisions, VCRs or DVD players because research clearly demonstrates that screen time does not benefit children. Your child will spend time outdoors every day, regardless of the weather, getting their hands dirty. With outstanding care, large outdoor playgrounds and safe and secure facilities, it’s no wonder Aa to Zz is consistently named one of the top preschool programs and child care centers in the state by the Central Penn Business Journal.
